HelioClim-3 solar radiation database services available in annual subscriptions
Weather services available in automatic access (API)
Automatic access to MERRA-2 meteorological data (1985 -> a month ago)
Purchase an annual subscription to automatically access MERRA-2 meteorological data, from 1980 up to about a month ago.
Automatic access to GFS meteorological data (2019 -> current day + 15)
Purchase an annual subscription to automatically access GFS forecasts 0.25° meteorological data, from 2019 up to current day + 15 days
Solar radiation time series and volume of data available on-demand
HelioClim-3 solar radiation database
Provision of one, a few, or of a large volume of HelioClim-3 version 5 time series
Please specify :
NB: For more than 5 time series, it is usually more economic to opt for an annual subscription.
Example of Backtracking: North-South horizontal one axis system, taking into account the following limitations:
Solar radiation under clear-sky conditions:
McClear fix-tilted service
Provision of one, a few, or of a large volume of McClear clear sky radiation values over a fix-tilted surface
Ask for time series in CSV format of McClear clear sky values containing all the radiation components over a fix-tilted and the horizontal plane. It can be used as an envelop for monitoring applications. Please specify :
NB: McClear radiation values over a horizontal plane and DNI are available for free via this Web interface within the framework of the CAMS project. A small fee is applied to computed the values over a fix-tilted plane. Prices on request.
Typical Meteorological Year on-demand
Provision of one, a few, or a large number of Typical Meteorological Years (pessimistic P90 or typical P50 scenario) at hourly time step
TMYs, are generated from the satellite-derived solar radiation database HelioClim-3 and from the MERRA-2 meteorological parameters. Please specify:
Problems with your in-situ measurements?
|Check and correct your data|
You are facing issues in the measurements with your instrument? You would like to check if your instrument is correctly calibrated? You are observing time shifts in your time series?
This service is the opportunity for you to get the best of your data =>
Do you have gaps in your data?
Our routines are capable of completing any time series of solar radiation values (satellite-derived or in-situ measurements), as well as the meteorological variables time series containing holes.
Calibration of long term HC3 time series using in-situ measurements
An expertise is provided to offer you a better knowledge on the quality of your in-situ measurements. A NDA is signed. An example of Quality Check report is included in the Calibration report (see below).
Please also try our SoDa online interface to check the quality of your measurements =>
This service delivers a complete report on the quality (QC, which stands for Quality Check) of the in-situ measurements, together with the calibration results of the long term HelioClim-3 (version 5) time series with the short term time series of in-situ measurements.
