Improving the HelioClim Databases and Preparing Future
Mines ParisTech - Armines is working on the most recent database HC-3 to improve its quality (more information).
Mines ParisTech - Armines is also working on the consistency between the databases HC-1 and HC-3 in order to create consistent time-series of daily values of radiation from 1985 to today, having the quality of the HC-3 data.
A new method Heliosat-4 is in preparation to process Meteosat images; its exploitation will create the database HelioClim-4.
