Data from the Japanese geostationary meteorological satellite are used to map surface albedo in Tasmania, Australia. Satellite data are corrected for atmospheric depletion and the narrow spectral window of the satellite sensor. The effect of non‐Lambertian reflection is discussed. A composite albedo map is presented based on eight mostly cloudless images taken at 10.00 and 13.00 local time in a period spanning the end of January to the beginning of February, 1985. The map features a distinct east west gradient in the albedo, with lowest values measured in the rain‐forest environment of the western highlands. Highest values are observed among areas of cleared farmland in the eastern midlands.
