CM SAF Solar Radiation


The solar radiation data made available here have been calculated from the operational solar radiation data set provided by the Climate Monitoring Satellite Application Facility (CM SAF). The data available here are only long-term averages, calculated from hourly global and diffuse irradiance values over the period 2007-2016.



The data sets in this section all have these properties:

  •  Format: ESRI ascii grid
  •  Map projection: geographic (latitude/longitude), ellipsoid WGS84
  •  Grid cell size: 1'30'' (0.025°)
  •  North: 65°01'30'' N
  •  South: 35° S
  •  West: 65° W
  •  East: 65°01'30'' E
  •  Rows: 4001 cells
  •  Columns: 5201 cells
  •  Missing value: -9999

Solar radiation data sets all consist of the average irradiance over the time period in question, taking into account both day and night-time, measured in W/m2. Optimum angle data sets are measured in degrees from horizontal for a plane facing the equator (south-facing in the northern hemisphere and vice-versa).
