THE ATMOSPHERIC PARAMETER RETRIEVALS OVER THE QINGHAI-XIZANG PLATEAU AND THE INFLUENCE OF CIRRUS CLOUD ON THE TEMPERATURE RETRIEVALS

Applying the simultaneous physical algorithm for retrieving temperature and moisture sounding, the atmospheric parameters are calculated over the Qinghai-Xizang Plateau. Comparisons are made of the atmospheric parameter retrievals with colocated RAOB data. The comparison results show that the temperatures can be retrieved with an accuracy of m can bias 2.50℃, RMS difference 30℃ and water vapors with an accuracy of mcan bias 20%,RMS difference 28%.Also, this paper reveals the influence of cirrus cloud on the temperature retrievals using the semi-transparent discrimination quantitative technique.
