Tropical glacier Huayna Potosi located in Cordillera Real in Bolivia was the main object in this paper. This study obtained two main parameters related to atmospheric conditions, i.e. diffuse fraction and atmospheric transmissivity, to evaluate the solar radiation distribution for the study of tropical glacier melts. The parameters were calculated by physically-based solar radiation formulas and then refined with observed data at ground level. These deduced parameters were conversely applied as input to GIS solar radiation model to obtain monthly spatial distributions of solar radiation considering atmospheric conditions and topographic from June 2011 to May 2012. Spatial distribution of glacier melt was finally simulated by applying glacier melt model considering air temperature and solar radiation.
