In order i o provide more realistic data of the surface albedo and the soil moisture content for our model, based on the current available albedo data, a comprehensive estimation has been done in the past years f vhich composites a set of data including the surface albedo and soil moist ure content for each season and year- aver age over a domain of 0°-180°E and 30°S-90°N with 2.5×2,5 deg. reso lu t io n.Then the c om par a ti ve study is made with the data from other source. Using the observed data over Plateau, by means of the statistical correlation analysis,an empiric al formula of surface albedo is found as a function of the solar zenith and the s oil moisture content near the sur -face. Fin ally, three sets of numerical tests are performed. The impact of surface albedo data on the surface diabatic heating is addressed.
