Description :
Based on DEMs of 25m resolution, a reversed model is constructed, with which temperature is simulated to the corresponding slope unit from the solar radiation. Taking Yaoxian county as a test area, and mean monthly temperature data as basic information sources, which are collected from 15 weather stations from the year of 1970 to 2000, a simulation for the solar radiation cel by cell is completed. By simulating solar radiation at each slope and flat cell unit, the terrain revised temperature model could be realized. The accuracy of simulated temperature in mountainous area is higher than it is in flat area.
