The document summarizes a study modeling daily net shortwave radiation (NSSR) over rugged surfaces using MODIS atmospheric products. It presents the background of the study, data and methodology used, results and discussion. The results show good agreement between modeled and observed NSSR values for different locations with R^2 values from 0.71 to 0.93. However, there are errors from spatial resolution gaps and coarse MODIS data. The conclusion is that terrain attenuates NSSR under clear sky while clouds play a greater role under cloudy sky, and MODIS can be used to moderately map NSSR over rugged surfaces.
