Other AbstractThe mu lt ichannelm icrow ave radiometer (RAD) on2aboard SZ24 spacecraf t w as the f irst spacebo rne m icrow ave radiometer in Ch ina w h ich launched at the end of 2002. In o rder to app ly the b righ tness temperatu res ob tained by RAD, W e developed an an tenna pat tern co rrect (A PC) algo rithm s fo r deriving b righ tness temperatu res f rom calib rated an tenna temperatu res fo r all RAD f requencies and incidence angles.A set of stat ist ical algo rithm s of ret rieving sea su rface temperatu res (SST ) , w ind speeds (W S) ,vo lume w ater vapo r con ten ts (WV ) above the global ocean w ere pu t fo rw ard. W e compared the ret rievals w ith geophysical p roduct s of TM I. Rm s of 2.13℃ fo r SST ,0.44m ös fo rW S,and 2.80mm fo rWV w ere ob tained f rom comparing respect ively.A t the end of the paper,we gave a summary of comparison s. A f ter delet ing the matched data w ith rain, i.e , vo lume liqu id con ten t s above 0.3mm ,we derived SST ,WS, and WV w ith rm s of 1. 40℃,0.35m ös and 2.71mm , respect ively, w h ich show ed that rain has great effect s on the ret rieving these parameters, especially on SST ret rievals. Genarally, B righ tness temparetu res by vicariou s ex ternal calib rat ion can be u sed fo r ret rieving SST , WS, andWV at certain accu racy.
