Combining the global distributions of black carbon(BC) mass concentration given by GADS(Global Aerosol Data Set),The direct radiative forcing due to BC have been calculated with an improved radiative transfer model under clear sky in both winter and summer.

Using the dust distribution data in spring 2001 the radiative heating(cooling) rates over deserts of China and the North Pacific Ocean are calculated and the impacts of low,middle and high clouds on the heating rate are discussed with a radiative transfer model.

In order to study the optical attenuation properties of the sea ice and find out their major influencing factors in the Liaodong Bay, we established a radiative transfer model from the historical investigation data and in-situ measurements.

SBDART is a popular model to compute plane-parallel radiative transfer in recent years.

To achieve this target,the radiant effect modules of water content are being developed in both RTTOV and CRTM,which are two popular rapid radiant transfer models developed by EUMETSAT Satellite Application Facility on Numerical Weather Prediction(NWP SAF) and USA Joint Center for Satellite Data Assimilation(JCSDA),respectively.
