Main content:

A bitmapped map. The map contains mean total solar radiation for December.

Classifier precision:

Total solar radiation expressed in kcal/cm╤ with precision within 0.5 kcal.

Map compilation procedure:

The map was compiled using data found in the Atlas of the Terrestrial Globe's Thermal Balance (1963) and data on total solar radiation in the nodes of the regular grid with a latitudinal and longitudinal spacing of 2.5 degrees found in the Surface Solar Irradiance database, NASA GISS, USA (1997). The database contains verified data on total solar radiation for the period from 1984 to 1991. The data have been obtained via the Internet from an FTP server: ftp:/data/inter_disc/radiation_clouds/solrad_sw/yyyy/.
