SOLAR IRRADIATION, ULTRAVIOLET, METEOROLOGICAL AND ATMOSPHERE AVERAGE AND REAL-TIME MAPS

Last update: April 2020

 

We provide average and real-time maps over the region of your choice:

  • HelioClim-3 solar radiation maps at real meteorological conditions (with clouds) over the Meteosat-11 satellite coverage
  • McClear solar radiation maps at clear-sky conditions (without clouds) over the world
  • Top of atmosphere (ToA) solar radiation maps over the world
  • HelioClim-3 Ultraviolet radiation and UV index maps at real meteorological conditions (with clouds) over the Meteosat-11 satellite coverage
  • Meterological maps over the world (from MERRA-2 and GFS Forecast services)
  • Atmosphere composition maps over the world: Aerosols Optical Depth, Water vapor, Ozone (O3)

HelioClim-3 Solar Radiation

We provide solar radiation average maps on-demand from HelioClim-3 version 5 database.

When you wish to order such a map, please specify the following elements:

  • Provided format: 16 bits GeoTIFF and 8 bits GeoTIFF (version compatible with Google Earth)
  • Solar radiation components:
  • Global Horizontal Irradiation (GHI)
  • Direct Horizontal Irradiation (BHI)
  • Diffuse Horizontal Irradiation (DHI)
  • Global Tilted Irradiation (GTI)
  • Direct Tilted Irradiation (BTI)
  • Diffuse Tilted Irradiation (DTI)
  • Global Normal Irradiation (GNI)
  • Direct Normal Irradiation (BNI)
  • Diffuse Normal Irradiation (DNI)
  • Specify: calibrated maps (or not) using ground station measurement(s)
  • Specify: taking into account (or not) the shadowing effect of the far horizon (SRTM) - NB: this option is relevant only for 1 km spatial resolution maps.
 

Average solar maps

We provide yearly, monthly, and daily averages maps.

Real-time solar maps

We provide an access in real time to HelioClim-3 version 5 irradiation maps of the area of your choice.

This service provides 15 min bitmap maps in TIFF format in real-time (h-15 min) during daylight time from 3:00 TU to 20:45 UT.

For more detail, please refer to the description of the Map service.

McClear clear-sky solar maps over the world

This service delivers worldwide solar maps at clear-sky conditions (without clouds) of :

  • Global, Direct and Diffuse irradiations on Horizontal surface
  • Direct Irradiation on normal plane.
 

Average clear-sky solar maps

The temporal coverage for the calculation of the averages maps is from January 2004 onwards.

 

Real-time clear-sky solar maps

This service delivers McClear irradiation maps at clear-sky conditions: 

  • in real-time (h-15 min)
  • for yesterday and for current day. 
 

Top of Atmosphere (ToA) solar maps over the world

This service can deliver ToA irradiation on horizontal plane at the top of atmosphere (Wh/m²). The spatial coverage is worldwide.

 

Average solar maps

The temporal coverage for the calculation of the averages maps of this service is from January 2004 onwards.

 

Real-time solar maps

This service can deliver ToA irradiation on horizontal plane at the top of atmosphere (Wh/m²) in real-time.

 

Ultraviolet radiation and UV index maps

UV components (Wh/m²) available are:

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

Actual method is Wald (2012). 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.

 

Average UV maps

The temporal coverage for the calculation of the averages maps of this service is from February 2004 up to yesterday.

 

Real-time UV maps

We provide an access to real-time UV maps on the area of your choice.

 

Meteorological maps over the world

We can create maps of these meteorological components:

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

Average Meteorological maps

We deliver meteorological average maps from MERRA-2 service (temporal coverage from January 1980 up to last month).

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