The HelioClim Databases - Solar Radiation Values Derived from Meteosat Satellites
There are several databases in the HelioClim family of the Mines ParisTech - Armines. A summary is given below.
| Name | Status | Geographical Coverage | Spatial Resolution | Period | Temporal Resolution | Update | Parameters | Method |
|---|---|---|---|---|---|---|---|---|
| HelioClim-1 | Version 4 | Lat: -66; +66 Lon: -66; +66 |
Approx. 20 km | 1985 - 2005 | Daily | None, except new versions | Irradiance, irradiation, global on horizontal | Heliosat-2 |
| HelioClim-2 | Version 1.0.1 | Lat: -66; +66 Lon: -66; +66 |
5' of arc angle. Approx. 10 km at mid-latitude | 2004 onwards | Hourly | Every hour, real time | Irradiance, irradiation, global on horizontal | Heliosat-2 |
| HelioClim-3 | Version 1.0 | Lat: -66; +66 Lon: -66; +66 |
Approx. 5 km | 2004 onwards | Quarter hourly | Every 15 min, real time | Irradiance, irradiation, global on horizontal | Heliosat-2 |
| HelioClim-4 | In progress | Lat: -66; +66 Lon: -66; +66 |
Approx. 5 km | 2004 onwards | Quarter hourly | Two days delay | Irradiance, irradiation, global, direct and diffuse on horizontal, spectral distribution | Heliosat-4 |
Statistics on Access to the HelioClim Databases
 |
This graph exhibits the number of requests made to the HelioClim databases per year. Data for current year result from projection. HC1, HC2, HC3 means respectively HelioClim-1, -2 and -3. A request may deal with a single geographical point or an area, a single instant or a large time period. Prior to 2006, the amount of data for one request was limited to 1 year for daily values and 1 month for hourly values; this explains the fall in request number in 2006 compared to previous years. |
