Other AbstractThe mu lt ichannelm icrow ave radiometer (RAD) on2aboard SZ24 spacecraf t w as the f irst space-borne m icrow ave radiometer in Ch ina w h ich launched at the end of 2002.In o rder to calib rate quan tat ively it sperfo rmances and respon ses to the given target s m icrow ave radiat ion, and validate the accu ry of it s p roducts,we carried on an in situ test w h ich w as conducted on L iuhua 1121 oil platfo rm f rom Dec 27,2002 to J an 9,2003.We employed a multiband microw ave radiometer (MMR ) operat ing at 6. 6, 13.9,19.35,22.235,and 37.0GHz, in to tal pow er mode. By ro tat ing the ho rn an tenna, w e ob tained b igh tness temperatu res in vert ical polarization, ho rizon tal po larizat ion, po sit ive 45 degree linear po larizt ion and negat ive 45 degree linear po larizat ion.This paperwe first gave a general review of the experiment, then expanded the resu lt smeasued by the seno rs, and anylysed in detail atmo sphere effect s on the in situ measu rements for ex rapo lating the su rface brigh tness temperatu re to the level at RAD an tenna. Becau se the su rface measu rements were all co llected at a certain point,while radiat ion RAD received were from all direct ion w eigh ted by it s an tenna pattern s,we developed an algo rithm of relat ing bo resigh t b righ tness temperatu re at the su rface to the w eigh ted an tenna temperatu re at RAD an tenna ou tpu t. Finally,we illu st rated the MMR resu lts corrected af ter app lied the algo rithm and compared w ith co2located RAD measu remen t s.
