ESTIMATION OF SURFACE ALBEDO DISTRIBUTION IN LUTZOW-HOLM BAY AND ITS NEIGHBORHOOD WITH NOAA/AVHRR DATA
A method has been developed for estimating the filtered narrow band surface albedo with NOAA/AVHRR data, and has been applied to analysis of the surface albedo distribution in Lutzow-Holm Bay and its neighborhood, Antarctica, in 1990. As a result, 16 maps of the surface albedo distribution have been...
