#193 Atmosphere Linke Turbidity factor Development of new clear sky model May 2021
User: Cesar. D. Sánchez-Segura, PhD student, Centro de Investigaciones en Óptica, Mexico

"The project I am developing is about the forecasting of the global horizontal, diffuse horizontal and direct normal irradiance components in the short time using a cathadioptric vision system. Our proposed forecasting approach aims to use the DNI value under clear sky conditions as a reference assuming that no clouds block the sun. There are more than 70 clear sky models in the literature, however many of them use input variables that are difficult to obtain. In addition, several models are calibrated for specific locations and climates.  This is why we developed a new clear sky model but we need to know its performance and this is why we want to compare it against other models. This is why we contacted SoDa Service to request monthly linke turbidity coefficient data from various locations around the world to implement various clear sky models that use this variable. Finally, I thank SoDa Service for their kind and prompt attention in providing the requested data."

Nous négocions des contrats d'approvisionnement avec des producteurs, nous répondons à des appels d'offres publics de fourniture d'électricité, et nous optimisons l'ensemble de ces contrats de manière à équilibrer notre portefeuille. Au quotidien, Selfee doit prévoir la production de ses centrales pour chaque demi-heure le lendemain. Les centrales photovoltaïques étaient jusqu'à présent minoritaires dans notre portefeuille, mais cela va évoluer rapidement en 2021 et nous avons besoin d'améliorer la fiabilité de nos prévisions, ce que nous espérons obtenir avec le service AI Forecast de SoDa. Nous avons une appréciation particulièrement positive sur la prise de contact, les informations transmises et l'approche client que vous mettez en œuvre."

#191 Atmosphere Linke Turbidity factor Computation of clear sky DNI days May 2021
User: Jorge Insa Tello, RPOW, Dubai, UAE

"I work for RPOW Consulting, and I am currently working in DEWA Phase IV (700MW CSP + 250MW PV Hybrid Project) as Commissioning Manager and CSP Performance Specialist. I have been working for CSP Industry for the last 16 years in several companies related to CSP Industry (EPC Contractor side) such as Abengoa and Sener.
I need such Linke turbidity factors to calculate the clear sky DNI in DEWA location (close to Dubai), as a reference to compare with real DNI and provide some classification of days.
These clear sky days, calculated hourly during a whole year, will be compared with our TMY to see "how good the TMY was", and to calculate MAXIMUM "reasonably" expected could be the yearly production of the CSP Plant.
I'm happy to see SoDa is still working, I cannot find anywhere else how to get them. I used SoDa in my early ages almost everyday, I see that your service has been improved. Keep up the good work!"

In this framework we have identifies the CAMS data as a very important source of information. Related to th SoDa service, both SoDa page and CAMS data offers very helful information and in a very usabble way, the fact that R package is available to easy the data download and reading is also an important feature that must be remarked under our point of view."

#186 Radiation HCdayDNI Modelling biomass-solar parabolic trough collector system for industrial tea drying February 2021
User: Philip Akello, PhD student at the Institute of Energy & Environmental Technology, Kenya

"My name is Philip Akello, I work at Christian Aid as the Africa Policy Lead on Climate Change. I am also a PhD student at the Institute of Energy & Environmental Technology (IEET) at Jomo Kenyatta University of Agriculture & Technology (JKUAT) in Kenya. My Thesis is on modelling biomass-solar parabolic trough collector system for industrial tea drying, with the goal of ascertaining the availability of adequate solar radiation (DNI) for tea drying in the tea growing highlands of Kenya. The final analysis will present different hybrid configurations that tea companies can adopt to enhance their net zero ambitions while at the same time reducing on their production costs. Of course use of solar collectors will equally reduce on land space that would otherwise have been used to grow trees used for tea drying, as is the current practice. This research will provide the much-needed evidence for my Pan African Advocacy work on climate change mitigation at Christian Aid. I am therefore excited to get solar irradiance (DNI) data from SoDa Service to pioneer this type of research, since currently, there's no application of solar collector technology for industrial heating in the whole of Sub-Saharan Africa. The data will strictly be used for research purposes and will not be sold nor otherwise made available for any other third-party use."

#174 Radiation HC15Incl&meteo To assess the long-term average solar resource for our independent PV yield analyses March 2020
User: André Schumann, SolPEG, Germany

"Hello, this is André from SolPEG. We are a long-term customer of SoDa services and typically consult HelioClim3 monthly data as one of several data sources to assess the long-term average solar resource for our independent PV yield analyses. This time we worked with a sub-hourly HC3v5 time series for a site in Ireland where we had 1 year of precise ground measurements available. It has been possible to calibrate the satellite data to the ground measurements with good results on monthly level. In total we worked with two time series from different providers. It turned out that the HC3v5 data set was especially useful for the months November to January but also showed good correlation for the rest of the year. The support by the SoDa team had been friendly, prompt and professional as always."

Ces deux domaines nécessitent d'être en mesure de modéliser la production d'un actif, notamment photovoltaïque, en convertissant des données météorologiques en puissance injectée sur le réseau.

BCM Energy est une PME française maîtrisant l'intégralité de la chaîne de valeur de l'électricité verte, de l'agrégation de production renouvelable à la fourniture d'une énergie 100 % verte via la marque Planète OUI. Le fournisseur propose à ses clients une solution complète d'autoconsommation photovoltaïque, basée sur un simulateur qui permet de dimensionner de façon optimale son installation. Ce simulateur nécessite la modélisation de profils de production photovoltaïques, eux-mêmes générés via les données d'irradiance AGATE mises à disposition par le webservice. Les données du CAMS Radiation Service sont elles aussi utilisées pour la modélisation de profils de production photovoltaïque historiques – employés dans des études de risques. Finalement, les données d'irradiance par temps clair du modèle CAMS McClear sont employées pour affiner certaines étapes de la modélisation de production PV.

BCM Energy est très satisfaite de l'utilisation des données SoDa. Plusieurs études et validation menées en interne ont démontré leur qualité en termes de précision et d'homogénéité. Les webservice sont de même accessibles en continu, ce qui permet de les intégrer avec fiabilité dans différents processus de l'entreprise. Pour tout type de données d'irradiance, il est ainsi fortement conseillé de se tourner vers SoDa!"

#157 Radiation AGATE dataset Agroforestry applications Dec. 2018

User: Maurizio Pieri, researcher at the Institute of Biometeorology of the National Research Council (IBIMET-CNR), Italy
" I work at the LaMMA Consortium (http://www.lamma.rete.toscana.it/en), a public consortium between CNR and the Tuscany Region. IBIMET works to define strategies, develop technologies and explore practical solutions to solve various environmental problems mostly of an agronomic nature due both to the use of the soil by man and to the effects of climate change. The LaMMA participates in Italian and international research projects and offers meteorological and climatological monitoring services at regional and national level. Over the past few years, the LaMMA has developed a methodology for estimating the daily solar global radiation based on satellite data (MSG). These data are used as input in some bio-geochemical models (BIOME-BGC) for agroforestry applications. AGATE data could be used to compare and validate our estimates and, if the spatial resolution of the data allows it, use them directly as input in our models. We use SoDa service data for several years. In particular, the CAMS products are certainly among the most reliable and constitute an international reference for research and operational applications concerning solar radiation."

User: Oihan Goenaga, Industrial engineer currently working in e-mobility
" I wish to implement an off-grid self-sufficient solar system at my parents' home. For this I have developed a Matlab code that simulates the radiation and power outcome of the system with different panel layout, inverter and battery capacity. The problem is that I lack of the data to make it accurate. If it works I would like to develop more projects like this. My daily work is not related to photovoltaic systems, I work developing high voltage electric vehicles. Nowadays I am working on an electric minibus for the city of Barcelona. The data will be used to simulate and estimate what combination of photovoltaic panels, solar inverter and battery capacity would fit best to each use case. I would be really grateful if this little project worked with your help and hopefully become something greater in the future."

I don't intend on using the data at the company where I'm currently employed. Like I said, my intention is to use the data inside a local competition to devise a "proof of concept" for an online platform that could help people analyze the solar potential of the region they live in (Urban Life Hackathon powered by ESA - the European Space Agency). I developed a similar project last year at the NASA Space Apps competition, which won first place at the local level and went into the finals. Here's a link of the 30s video submission we made to the NASA jury: ICARUS. This time I want to continue to develop this idea using real data, which you can provide.

"I'm working at the Research Centre of Energy Economics (FfE e.V). The FfE is an independent research institute that focuses on energy technology and energy management issues (https://www.ffe.de/en/). As a research assistant with a geographical background I'm partly responsible for our data management system (based on Postgresql) with all of its data, spatial analysis with GIS (especially PostGIS) and the regionalization of information which is relevant for our energy system. For example we regionalize the future installed capacity of renewable energy plants for the German 'net development plan' or perform power grid calculations. For calculating regional power profiles of photovoltaic plants for different weather years I would need time series of the irradiation in a highly spatial (a 0.2° grid step is perfect) as well as temporal resolution (a time step of one minute would be devine). At the moment we use the cosmo-eu modell with a temporal resolution of one hour. With the use of the AGATE-data we expect a significant improvement of our model. Up to now I'm highly satisfied with the SoDa Service ☺."

"In order to create synthetic GHI data series for a specific site, I used a helioclim-3 10 years series. I particularly needed clear-sky and real radiation values with a resolution of 15 minutes. Through the historical series, it was possible to create a simulator that, using Markov chains, is capable of generating a large number of data series with indefinite extension and  statistical characteristic similar to the original. The synthetic data was later used to simulate the power output of a photovoltaic plant and evaluate (technically and economically) the effects of different storage system technologies. I want to thank SoDa for the support. The series was indispensable to my work for the master thesis".

User: José Manuel Fernández Guisuraga, student at the University of Leon, in Spain.
"In conjunction to other inputs such as cloud coverage, relative humidity, particulate matter, wind speed and pressure, I needed daily radiation values in order to study the factors influencing nucleation of raindrops in a urban and a rural area. I chose two sites in Portugal since all the parameters except solar radiation are available. I thank Transvalor and SoDa which sent me these two time series needed to complete this study as part of my end-of-degree project. I am very satisfied with the service provided by SoDa; the requested data has a great overall quality and it fitted perfectly with my study".

#60 Radiation HC3v4day Modelling of spruce bark beetle population dynamics in the Tatra Mts. (Carpathians), using satellite derived solar radiation data Oct. 2014

User: Pavel Mezei, Institute of Forest Ecology of the Slovak Academy of Sciences.
"Spruce bark beetle can cause widespread damages during its outbreaks in spruce forests. Norway spruce is the most common tree species in Central Europe, especially in Slovakia, Czech republic, Austria and Germany.
The yearly development of spruce bark beetle depends on temperature and solar radiation. There is an existing model on the phenology (number of generations per year) of Spruce bark beetle, called PHENIPS, and one of the basic input, among with maximum air temperature and mean air temperature, is the daily solar radiation in Wh/m2.
We were very satisfied to receive the daily HelioClim-3v4 irradiation values for 5 sites in the Tatra Mts, which contributes to our modelling aiming at showing a potential statistical relationship between spruce
bark beetle population dynamics and spruce tree mortality

#59 Radiation HC3v4hourIncl Assessment of PV power source reliability, off-grid, wireless systems Mar. 2014

User: Gustaw Mazurek, assistant professor at the Warsaw University of Technology.
Helioclim-3 database offers on-demand solar radiation data in horizontal, inclined, and normal plane and in fine spatial and temporal resolution. Access to the data is granted via simple but powerful web interface.
Results of our research show that Helioclim-3 database delivers estimations of solar irradiation on a tilted plane (GTI) with noticeably better accuracy than other databases available in the web. Moreover, thanks to fine temporal resolution and timeliness of this database, it is possible to evaluate the performance and reliability of any solar system with higher precision and confidence level.

User: Fabian Fogelberg, Master's Thesis Intern at Viktoria Swedish ICT, Chalmers University of Technology, Gothenburg, Sweden.
"In my master's thesis, I looked at the energy balance and possible station design of a solar powered bike sharing system with electric bikes. As the solar panels would be placed in an urban setting where buildings will shade the panels, it is not clear how the panels should be oriented for maximum energy yield. With the detailed datasets from SoDa however, it was possible for me to both calculate the optimum orientation as well as model the pool system in high temporal resolution."

The main goal of this collaboration is to be able to trust the estimations done by SoDa as reliable measures in case of exceptional situations that may occur in facilities located all over the world, such as damages to certain elements of their very own weather stations.

#53 Radiation hc3v4hourIncl solar potential of Denmark Nov. 2013

User: Patrick Narbel, PhD Research Scholar, Norwegian School of Economics, Bergen, Norway.
After forecasting the electricity production profile of two hypothetical wind farms in Denmark, I tried to do the same with a hypothetical solar power plant. Using this information, I want to show that solar power can be valuable in Denmark, even though solar radiation levels are not that "exciting" in that country (the value of solar power comes from the fact that there is already a lot of wind and adding more wind turbines just adds power when there is no need for it, whereas solar can contribute during times with little wind). I want to use this result to show that existing policy instruments need to be adjusted in order to reflect this "value". SODA provided me with the data on solar radiations, which made the whole comparison between electricity production from wind and sun comparable.

#50 Atmosphere Linke turbidity factor Thermic model for cockpit Jul. 2013

User: Joseph Guindi, Ingénieur Thermicien, Altran GmbH, Hambourg
"Mon projet consiste en la création d'un modèle thermique d'une cabine de pilotage afin de calculer les charges thermiques (chauffage et refroidissement) et le confort des pilotes. Un des composants les plus importants de l'équilibre thermique de la cabine de pilotage est tout particulièrement la radiation solaire. Toutefois, je trouvais que la méthode employée méritait d'être optimisée, alors j'ai entrepris de réviser sa méthode de calcul afin de pouvoir la déterminer peu importe la localisation d'un avion, au sol ou en vol, et de tenir en compte autant de variables possibles. Étant donné que la turbidité est un facteur régional qui ne fluctue pas de manière journalière, et qu'elle a un effet substantiel sur la radiation solaire et donc le confort thermique, il était rendu nécessaire et utile de la modéliser. Il était aussi essentiel de limiter le nombre de variables environnementales à rentrer dans l'outil afin de ne pas le rendre trop lourd. La base de donnée à l'échelle planétaire mise à ma disposition via le service SoDa permettra éventuellement à l'ingénieur de placer son avion où et quand il voudra, et de calculer automatiquement et correctement la radiation solaire transmise à la cabine de pilotage (ou ailleurs dans l'avion, à l'avenir).

He writes: "We use the data in dynamic thermal modeling of buildings and durability modeling of facades. It is quite challenging to find hourly solar data. While other meteorological elements are collected, solar data is often missing. It may take many email exchanges with Meteorological Institutes to just discover that data does not exist for a particular time window in one particular station. SoDa offers wide areal coverage and data presented in a very accessible format. A potential user can quickly understand what data there is, and how it will look like when downloaded. This is very important advantage for non-meteorologist users, who come from the side of the applications".

#39 Radiation HChourIncl averaged over each week Sizing  of solar system in South Africa (not possible to export energy in this country) Oct. 2012

User: Mr Johan Buys, solar project developer, Paarl, South Africa
"We had previously used the free database to generate estimates, but the data was for one year only and in some days incomplete. In October 2012, we made contact with Transvalor to enquire how we can get bulk data for multiple periods. We were able to get the data very quickly. To normalize the data we excluded the invalid days, produced data by week number and hour instead of day and hour, and then used statistical method to exclude the outliers.
The importance of this exercise is striking when one compares the normalized data to the total as well as any one year Single years varied by nearly 10% in total annual output. This variance is obviously even more extreme at the week and hour level. The resulting output (from simple spreadsheet exercise) now gives us a more reliable / bankable model of the probable solar irradiation for every week of a year and by time of day. This is important for planning our electrical loads and matching to our solar system, as systems in our country are not allowed to export - getting the sizing right is therefore crucial to the financial outcome".

"I am studying the ageing of different wood materials when exposed outdoors, especially how their appearance changes with time and how those processes can be receated in the laboratory. Material samples are exposed on vertical walls facing south, east, north and west. The prevailing weather conditions, especially wind driven rain and solar radiation, vary significantly depending on the exposure direction. Hence, it is crucl to not only know solar radiation doses on horizontal surfaces, but also on inclined surfaces, in my case vertical walls.
SoDa services provide easy and especially user-friendly access to those data. I also compared data measured on horizontal surfaces at the site and found a bery good correlation to data provided by SoDa. Also, I especially appreciated the up-to-dateness of the data.

It was very good. The reliability of the SoDa Service is excellent and it is very easy to use. However, the availability of the HelioClim database and of other databases changed during time and made our access difficult at times. We appreciated very much HelioClim when it was free. It would have been a good help to achieve our task. It is excellent, reliable, and provides long series of consistent values. However, it is too expensive; we cannot afford to suscribe to HelioClim data, nor to get conventional meteorological data".

#18 Radiation HC Building, Thermal Regulation 2000/2005 Nov. 2006

User: Bruno Peuportier, MINES ParisTech
Technical rules apply to building engineering; some of them relate to climate, including solar radiation and its three components: global, direct and diffuse. In France, it was shown that previous solar radiation data were obsolete (thermal regulation RT2000) and a new set is necessary (RT2005). The SoDa Service was used in this purpose in combination with data purchased to Meteo-France. It was found that using the SoDa Service provides a double benefit to create these new standards. It complements the data of Meteo-France when and where those are absent and provides in one click the three components while Meteo-France data are global radiation only and are to be entered into a specific software to obtain the other components. A revised standard data set was integrated into the standard RT2005.

These maps are much more accurate than the previous ones that resulted from interpolation of point measurements. The Rudjer Boskovic Institute helps local municipalities of Croatia in taking decision to invest in renewable energy systems for producing electricity in isolated sites.

#16 Radiation HC Horticulture, daylighting, horticultural lamps - Greehouses May 2006

User: Sander Pot, an Application Specialist Horticulture at Philips Lighting Professional Lamps,
Natural sunlight is the cheapest source available but for horticulture it is not always available in sufficient quantities. Especially in regions between 40 and 80 degrees latitude the amount of daylight required for good plant growth is limited during the winter. Therefore, during this period, the use of artificial light has become very common in greenhouses to increase production and quality. Philips is a company specialized in technology with a very strong lighting division. Philips is the world wide leader in offering horticultural lamps for the use of supplemental light in greenhouses. Sander Pot wrote: "The use of supplemental light is depending on many variables and the availability of natural daylight (global radiation) is one of them. When global radiation is lacking for good plant growth or for maintaining quality as it is often the case during winter, we can calculate how much artificial growthlight should be supplemented based on the need of the specific crop. Accurate knowledge about the amount of natural radiation is in this case essential. In horticultural areas this knowledge is often available since growers are using solarimeters on the top of their greenhouses. However in many areas, where horticulture is less developed or for potentional new horticultural areas, this information is not available or at least hard to get. For obtaining this information the use of the SoDa Service has shown to be very useful".

#15 Radiation HChour in wget SPYCE, a residential PV monitoring solution May 2006

SPYCE uses SoDa to monitor your PV system
PV system performance SPYCE is an internet service that detects and identifies failures in PV systems by daily analysing their performance. Because the energy output of PV systems strongly depends on the irradiation, SPYCE needs hourly irradiance data for the locations of the PV systems. Sandra Stettler, scientist in the SPYCE team explains: "To determine the performance of a PV system, current and precise irradiance data is absolutely necessary. With the SoDa data we have reliable, ongoing irradiation data for every location in Europe. It allows SPYCE to check daily the performance of all PV systems and to give alert to the operators if necessary." The SPYCE service is a Joint Venture of the Swiss companies Enecolo AG (photovoltaic experts) and Meteotest (meteorological expertise).

User: Mrs. Dalle, the Group Deceuninck
The Group Deceuninck, approx. 3000 employees worldwide, specializes itself in compounding, the design, development, extrusion and finishing of PVC systems and profiles for the construction industry and in recycling. Mrs Dalle is the responsible for guarantees and certificates, wrote that among her duties, she has to determine the amount of global solar radiation energy per year in a specific place in the world in kiloLangley per year, to help in fixing the strategy where the different raw materials, lacquers and foils are to be sold depending on the limitations specified by the supplier (solar radiation, climates, temperatures, rain, relative humidity) and finally to set up a warranty certificate depending on the specific region, use of the product, climate and solar radiation. Due to an excellent collaboration with the team in charge of the SoDa Service, she can now perform most of these tasks in a single click. In addition to solar radiation, the SoDa Service provides temperatures, and, relative humidity. Furthermore, the SoDa Service produced a worldwide map of the radiation that provides at a glance an accurate knowledge of the climate zones. Exploiting the SoDa Service represents a true gain in efficiency and in accuracy.

#11 Radiation HC Rural electrification using solar energy in Africa Jan. 2006

User: the company Lahmeyer, Germany
The German company Lahmeyer International provides the whole range of technologies and services with regard to energy infrastructure development and infrastructure improvement. Mathieu Sarran writes "Our consulting activities in rural electrification by means of solar energy request accurate data on solar radiation. In Africa, such data are inexistent in under-developed regions. Accordingly, Lahmeyer International install itself measuring stations. This induces costs and presence of local teams for data collection and maintenance. The availability of radiation data assessed from satellite images by the école des mines de Paris that can be accesssed through the SoDa Service is a real advantage for our company. The first benefit is that they are available at any site: there are more data than Lahmeyer International can install stations. The second benefit is that archives are available instantaneously while our measuring stations should work two full years before delivering a consistent and reliable time-series. Advantages are evident: fast access to information, reliability of information, large geographical coverage, dramatic decrease of costs for study and planning. By exploiting these data, Lahmeyer International can realise projects quicker, in a manner more reliable, more complete and more competitively. These advantages benefit also to the customers of Lahmeyer International since the studies cost less and are realised quicker".

#9 UV UV and spectral distribution UV exposure, campaign of comparison UV dosimeter mesurements versus HelioClim1 Sept. 2005

Users: Researchers in the field of dermatology, for a campaign of comparison between UVA and UVB collected with a dosimeter and the UVA and UVB estimated from the HelioClim1 dataset - UV exposure
Individual sun exposure can be assessed using meteorological satellite measurements. A study was performed to compare measurements of UVA and UVB exposure of children recorded with personal dosimeters with assessment through a detailed questionnaire and satellite measurements. Methods: 25 families with one index child participated in the study. Participants filled a questionnaire detailing daily activities, geographical location and circumstances of sun exposure. Corresponding satellite measurements of local UVA and UVB irradiation were obtained from the SoDa Service, and namely the database HelioClim. Results: Out of 353 days of sun exposure, 437 episodes were recorded with a dosimeter. Median duration of each session was 2 hours, 62 % of exposures occurring between 11 AM and 3 PM. There was a good correlation between measurements from dosimeter and satellite (r=0.48 for UVA; r=0.40 for UVB, Spearman correlation p<0.0001). Dosimeter records tend to underestimate the total exposure measured from the dosimeter (difference per session: 40 Wh/m2 UVA, 1.5 Wh/m2 UVB). The correlation was better for exposure in the sun (r=0.5 and 0.43 for UVA and UVB respectively), on the beach (r=0.57 and 0.42), at the seashore (r=0.64 and 0.40). Multivariate analysis adjusting for weather, exposure duration, horizontal or vertical use of dosimeter, shade, environment and activity showed that satellite measurements were only significantly influenced by the weather. Dosimeter records were essentially influenced by the type of use (81 % in UVA and 73 % in UVB decrease of measure when dosimeter was worn on the belt), exposures in the shade (54 % decrease for both UVA and UVB), environment (60 % decrease for UVA and 34 % for UVB for exposure in the country side). When adjusting for all variables, there was a significant independent correlation between dosimeter and satellite measurements (p < 0.0001 for UVA and UVB). Conclusion: Satellite measurements give a good estimate of individual UVA and UVB exposure, independently of exposure conditions and could be used to estimate actual exposure.

User: Yvonne Dauwalder from BKW FMB Energy Ltd, a Swiss company supplying energy to one million people in around 400 communities in Switzerland.
In 2004 BKW supplied over 6'900 Gigawatt-hours of energy to private customers and distribution partners. BKW produces energy from hydro, nuclear, solar and wind power plants and is the principal partner in Switzerland's largest alternative energy production plants (Mont Soleil solar energy plant, Juvent wind power plant and the Stade de Suisse solar power plant). Yvonne Dauwalder used monthly sums of irradiation provided by SoDa as part of a monthly report about key factors influencing electricity sales to small and medium-sized businesses. Quoting Yvonne "thank you very much for the extensive SoDa Services, it is very convenient to use with detailed explanations and most amazingly, it is for free. It truly is one of a kind on the web!".

#7 Radiation HC1 JRC integrates HC1 values into PVGIS over Africa May 2005

Within the framework of "PV in the developing world", mapping solar energy
Irradiance data were obtained by the European Commission's Joint Research Center (JRC) – Institute for Sustainable Development from the SoDa service. JRC selected the SoDa service because it offers long time-series of irradiance values (from 1985 onwards) over a very large geographical coverage and it enables automatic access on Internet (approx. 200 000 requests for a year, that is 4 million requests made by JRC for 20 years). JRC was thus capable of creating unique maps and derived products to assess the value and benefits of solar energy systems to produce electricity in Africa, thus helping in combating poverty and developing human welfare. These maps are provided to African countries and European authorities to help decision-makers. The potential power output from PV systems is compared to the average daily electricity consumption per capita in the countries in question. The potentials of PV appear clearly; the potential production is much larger than the present consumption.

#5 UV UV and spectral distribution Health, pregnancy and vitamin D insufficiency Jan. 2005

UK researchers from the University of Southampton, Royal London Hospital and Princess Anne Hospital Study Group, have studied the insufficiency of vitamin D in women of childbearing age. There is increasing evidence that the risk of osteoporotic fracture in later life may be determined, in part, by environmental influences during intrauterine and early postnatal growth. By studying a cohort of children, from birth to age of nine and their mothers during pregnancy, and by using UV data delivered by the SoDa Service, these researchers have found that maternal vitamin D insuffiency is common during pregnancy and is associated with reduced skeletal growth of the offspring during childhood; this relationship is mediated in part through umbilical venous calcium concentration. Vitamin D supplementation of pregnant women, especially during winter months, may lead to long-lasting reductions in the risk of osteoporotic fracture among their offspring. More on this story at the MRC Environmental Epidemiology Unit web site.
