Notes on data, analysis and

Estimates of radiation are based on the NASA Langley solar radiation data, which were derived from NOAA (National

compilation:

Oceanic & Atmospheric Administration) satellite observations recorded between March 1985 and December 1988. See

also Eberhard, AA. 1990. A solar radiation data handbook for southern Africa. Cape Town: Elan Press. The polygons

making up the shapefile were created from hand drawn contours on a hard copy map. This manual interpolation

approach was done by Peter Hutchinson using the point data from all available stations. Because the number of stations was small an

automatic interpolation produced nonsense results.
