A study of the emission over cirrus clouds on Tibetan Plateau

A method of estimating the outgoing longwave flux on. cirrus clouds is described. First geomeTRy mark model is set, and the scattered of cirrus clouds water content in vertical direction is assumed. Second the models are approximately simplified model gets the outgoing longwave flux on cirrus clouds.Both the results and satellite sounding data approximately reach the same results. The relations between the thickness of cloud and the outgoing longwave flux and the height form ground to the base of cloud and the outgoing longwave flux are respective.
