The principle and methods on thermal/vacuum(T/V)testing of microwave humidity sounder (MWHS)on FY-3B satellite were described;correction algorithms on calibration errors were developed,and some main specifications of MWHS-3B,such as linearity,sensitivity and calibration precision,were obtained. The parameters derived from the T/V testing had been used in in-orbit data processing to produce brightness tem-perature products in FY-3B ground system.
