A simple method that estimates spatial albedo distribution on glacier using satellite images was developed. Glacier for this study is Condoriri glacier in Bolivia. An albedoradiance relation is derived from a power function. Both observed albedo 0.08 on end moraine and maximum albedo on fresh glacier were used to decide constant numbers for all images on the assumption that they do not vary with time. As a result, 0.65 was decided as maximum albedo after optimization for a correction function of albedo. We evaluated the accuracy of calculated albedo using albedos 0.18 on bare ground. RMSE (Root Mean Square Error) indicates 0.091 on bare ground. Calculated albedos on all ground coverage by this computation method were in agreement with data from other estimation.
