| Abstract: | It is available to analyze on-orbit performance stability of MWRI by statistic histogram data of earth cold targets with stable brightness temperature. This paper analyzed on-orbit performance stability of MWRI by adopting the brightness temperature data onboard FY-3(02) satellite during February and July in 2011, showing that the MWRI onboard FY-3(02) meteorology satellite performs stable on-orbit, and the max fl uctuation of the coldest reference values of all the 10 channels are less than 1.8 K. |
