      The purpose of this study is to analysis monthly OLR of the Iranian surface. For this purpose, the ground OLR data was extracted and analyzed from the ncep/ncar database during the statistical period of 1354-1398. In order to extract the have been used in the Gards software and GIS. Findings showed that by examining the spatial index of Gi statistic, the hot spots of Iran's OLR are 99% and 95% in August, July, June, September and October. Hot spots correspond to areas of the tropics and to latitudes below 30 degrees north; Also, the maximum cold spots are at the level of 99%, 95% in February, December, January, March, April, and the maximum cold spots OLR from the northeast to the northwest.
