Estimating surface radiation budget over China in summer from GMS satellite data

The surface radiation budget is an important essential radiation parameter. In this paper, the basic relation between the measurements from the visible/infrared channel in satellite and the surface radiation budgets has been derived. According to this relation, some useful models of estimating the surface radiation budget are obtained by the observational data from the visible/infrared channel in GMS satellite and the observational data from surface radiation budget stations. With the most excellent one of these models, the distribution of radiation budget across China is obtained by the interpolation method. Compared to the actual observational data, this distribution has a better consistency with the actual results, which shows that this model is very effective in estimating the radiation budgets in China.
