| Abstract: | A new group of O2 absorption channels with frequency at 118.75 GHz was added in the new Microwave Humidity Sounder instrument onboard the Feng-Yun 3C satellite. And a comprehensive cloud detection scheme can be developed by combining the O2 absorption channels with frequencies ranging from 50 to 60 GHz in MWTS and the ones in MWHS. Since the high frequency and low frequency have the different performance on the scattering of cloud, meanwhile, based on the relationship of double O2 sounding channels under the clear sky condition, a new cloud detection scheme is developed. |
