Abstract HelioClim3v4-MC Monthly Diffuse Horizontal Irradiation for the month of Jan. 2005 in kWh/m2. Copyright 2013 MINES ParisTech / Transvalor

Diffuse irradiation received by a horizontal plane during the month of Jan. 2005 for the field-of-view of the Meteosat satellite. MINES ParisTech has developed the Heliosat-2 method that converts 15 min Meteosat images into irradiation maps and stores them into the HelioClim3 database. A monthly irradiation value is computed only if at least 25 daily irradiation values are available. The irradiation values of the missing days are computed by taking into account the mean value of the valid days and the length of each missing day. A day is valid if the HelioSat-2 method can be applied on at least one 15 min slot. Gaps in the day are filled by taking into account the available 15 min irradiation values and the length of the day.
The other irradiation components (direct, diffuse) received on an horizontal, tilted or normal plane are then computed and provided via the SoDa Service (www.soda-is.com and pro.soda-is.com) since 2003. Such data are used by academics for teaching and research in solar energy, environment, climate and others, and by companies for the sitting of solar plants (PV, CST), their sizing, and the monitoring of their production.
Since 2009, the French company Transvalor is in charge of the SoDa Service. Transvalor provides in addition a series of user-tailored services, such as these maps made with MINES ParisTech that combine HelioClim-3 data with an advanced model McClear that estimates the irradiation that should be received for a given site and given instant if the sky were clear, aka clear sky irradiation. Here MC stands for McClear. Transvalor and MINES ParisTech have set up the McClear Clear-Sky Irradiation service that delivers time series of clear sky global, direct, direct normal, and diffuse irradiation for any site in the world, any period of time starting in 2004 up to now, with a time step ranging from 1 min to 1 month. The McClear is an outcome of the MACC and MACC-II EU-funded projects.
