Solar Atlas

SOLAR, ULTRAVIOLET AND METEOROLOGICAL ATLASES

Last update: September 2020


An atlas is a set of digital maps available online used to exposed one or many types of data on a specific region.

We provide different type of atlases with the spatial and temporal coverage of your choice from February 2004 onwards.

We can deliver averages data but also yearly and monthly values.

SOLAR ATLASES

Solar atlases can include these features:

  • Global, diffuse, direct, reflected irradiation for actual weather conditions and clear-sky irradiation
  • At horizontal, fix-tilted and normal planes
  • Geographical coverage is Europe, Africa, Atlantic Ocean, Middle East
  • Spatial resolution is 3 km at Nadir, and approx. 4-5 km at 45° of latitude

ULTRAVIOLET ATLASES

Ultraviolet Atlases are built using Wald (2012) method. This method exploits HelioClim-1 Global Horizontal Irradiation values to estimate daily, monthly and yearly values of this radiation component from 1985 to 2005.

The same method is applied on HelioClim-3 GHI to estimate UV values with a time step that ranges from 1 min to 1 month from February 2004 onwards.

UV components available are:

  • UV-B (280-315 nm)
  • UV-A (315-400 nm)
  • UV TOTAL (280-400 nm)
  • UV ERYTHEMAL
  • UV INDEX

METEOROLOGICAL ATLASES

We can deliver meteorological atlases including these components from MERRA-2 database : 

Temperature (at 2 m), 

  • Relative Humidity (at 2 m), 
  • Pressure (at 2 m), 
  • Wind speed and direction (at 10 m), 
  • Rainfall, 
  • Snowfall,
  • Snow depth.

For more accurate data, we increase the spatial resolution with altitude parameters from SRTM.
