《Estimating the Correlated Observation-Error Characteristics of the Chinese FengYun Microwave Temperature Sounder and Microwave Humidity Sounder》
*V is vertical polarization,and H is horizontal polarization.
The radiance data from the MWTS and MWHS onboard FY-3A/B were used in this study.The MWTS and MWHS instruments were placed on FY-3A with an equatorial local crossing time of 1015(descending),and on FY-3B with an equatorial local crossing time of 1340(ascending).Figure 1 displays the weighting functions of the channels of the two sensors.These instruments can obtain the vertical atmospheric temperature and humidity in different layers.The MWTS channels are similar to those of the MSU channels and channels 3,5,7 and 9 of the AMSU-A.Table 1 lists the channel characteristics of the MTWS,including the frequency,main absorber,and peak weighting function height.Channel 1 is the window channel used to obtain the surface temperature and emissivity.The other channels are used to detect atmospheric temperature in the troposphere and lower stratosphere.The MWHS and MHS have five similar channels,with the MWHS also including a dual-polarization channel at 150 GHz(channels 1 and 2),while channels 1and 2 of the MHS are at 89 and 150 GHz.Channels 3–5of the MWHS can provide information on mid-to uppertropospheric humidity.The MWTS has 15 fields of view(FOVs)per scan line,a swath width of 2250 km,and a spatial resolution of 50 km at the nadir view.The MWHS has98 FOVs,each with a swath width of 2700 km,and a spatial resolution of 15 km at the nadir view.The channel characteristics of the MWHS are shown in Table 2.The satellite data used in this paper were derived from the China Meteorological Data Service Center(CMDC,http://data.cma.cn).
