In this paper the effects of stratospheric volcanic aerosols on longwave radiation budgets at the top of the atmosphere and on the surface and the infrared cooling rates in the atmosphere were investigated through radiative transfer calculations for different atmospheres under clear and cloudy conditions.

Heat transfer coefficient of convection,long wave radiation and vaporizing at exterior surface are analyzed,and simplified algorithm for total heat transfer coefficient is provided.

Based on 45-month NOAA satellite data of radiation, including the absorbed sun radiation, the albedo and outgoing long wave radiation (OLR), as well as the formula for the radiation budget, the features are revealed for the zonally and monthly averaged (total and component) radiation budget in the earth-atmospheric system.

According to the analyze to the calculated results,this paper shows that the long wave radiation thermal exchange model has a great influence on the space heating and cooling load.
