The aim of this study is to explore the role of land surface temperature on distribution of snow-covered days in Iran. Firstly, the land surface temperature data were obtained from NASA for 2003 to 2014 in the spatial resolution of 1×1 km. MODIS Terra and MODIS Aqua data were also downloaded from 2003 to 2014 in the spatial resolution of 500 * 500. After preparation of the data in MATLAB software, Digital Elevation Model of the country was applied to calculate the annual LST for each of the elevations grouped by 1 meter. The findings of this study revealed that in the extents of the country which annul LST is below 30 º C the environmental condition is suitable for the accumulation of snow cover. And it was also found that the LST is 30 º C for the elevations above 1700 m. findings also revealed that there is no snow-covered day for the extents that LST is 37 º C and the most number of snow-covered days can be seen in the regions that LST is 0 º C.
