|#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."

|#154||Radiation||AGATE Dataset||Simulate and estimate what combination of photovoltaic panels, solar inverter and battery capacity||Sept. 2018|
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."

|#142||Radiation||HC30DNI et HC30Incl||Modélisation du rayonnement solaire par ciel clair et modélisation d'un four artisanal||June 2018|
User: Martin Varnier, étudiant 2ème année CPGE PCSI au Lycée Gay Lussac de Limoges, France
" Le sujet que j'ai retenu pour mon TIPE est la modélisation sur Excel, du rayonnement solaire par ciel clair et la modélisation d'un four artisanal piloté en suivi azimutal par une carte Arduino selon les coordonnées sphériques du Soleil. Le 1er modèle est validé grâce aux données "Ciel clair" disponibles sur le site SoDa. Le 2ème doit l'être par des relevés expérimentaux de la montée en température du four. Mais la fin du mois de mai et début juin ont été particulièrement pluvieux, et l'irradiation reçue par le four ne correspond pas à celle d'un ciel clair. Il me faut donc travailler avec l'irradiation réelle, et c'est tout l'intérêt de la base de données de SoDa. Je suis très satisfait de la mise à disposition de cet outil au public."

|#132||Radiation||Agate data volum||Energy technology and energy management issues||March. 2018|
User: Fabian Jetter, Research Centre of Energy Economics (FfE e.V), Germany
"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 ☺."

"My name is Michel Guenther, I'm working on my master thesis in Luxembourg. The goal of the master thesis is to investigate if solar (supported) district heating is economically interesting in Luxembourg. Furthermore I'm going to analyze some energy storage options for the mentioned purpose (daily or seasonal storage). In a first step the obtained solar radiation data will be used to compare the energy output of some solar collector types with the actual heat load of the network. In the second step the data is used as input data for a Matlab simulink simulation of the complete system. I am very pleased with the data and the endless possibilities regarding time step and time period. Also the fact that the CAMS Radiation Service can be used for free is an important benefit and should be highlighted. On top of that comes a really good and fast service and customer support."

User: Calire Brousse, Ecole Supérieure d'Ingénieurs Léonard de Vinci, France.
"Les données fournis par SoDa nous furent d'un grand recours ! Nous sommes 5 étudiants et nous avons travaillé un an durant sur un projet: Solar-Home. C'est un logiciel de conseil énergétique qui permet à l'utilisateur de visualiser son potentiel de production d'énergie grâce au solaire, et d'obtenir une cartographie de l'ensoleillement de son toit au cours de l'année. Il nous fallait pour réaliser le logiciel des données météorologiques du lieu où se trouve le toit du batiment étudié. Ces données, très difficiles à trouver (surtout avec la quantité et la précision dont nous avions besoins) nous ont été fournis par SoDa. Notre logiciel peut donc désormais faire des calculs précis en utilisant un riche historique de l'ensoleillement sur les zones étudiées. Les bases de données de SoDa et de Transvalor sont très complètes et facilement utilisables! Cela a été pour nous un véritable coup de pouce, de plus l'équipe de SoDa nous a conseillés et aidés dans la construction de ce projet grâce à des explications et des précisions tout au long du projet."

Finally SoDa-website provided me all what I needed, the data was clear and easy to process. Also I contacted with the support and it was very quick and helpfull. I'm very satisfied to obtain the monthly Helioclim-3 data for the cities that I wanted, which allow me to make a comparative study for solar radiation in these cities".

User: Giovanni Carbone, engineering student at Sapienza, University of Roma.
"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".

"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."

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.

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.

"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).

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".

He is studying the climate change impacts on a drinking water reservoir system. He wrote "HelioClim data delivered by the SoDa Service were found to be close to our own measurements. 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".

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.

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".

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).

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.

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".

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.

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.
