Abstract: Based on measured albedo data of dry snow cover in field, the numerical range of spectral albedo in band 0.38-3.2,0.38-0,7 and 0,7-3,2 is given.How the factors of sun elevation, cloud and dirtiness influence on spectral albedo is discussed in this paper , and it will provide a part of basis for effective using satellite data to obtain albedo of snow cover in the ground.
