The Fengyun(FY)-3Csatellites was successfully launched on 23 December 2013and carries the Microwave humidity and temperature sounder on board which started its measurements since December 30.MWHTS observe the vertical distribution of atmospheric temperature and moisture.MWHTS is a cross-track scanning instrument which observing in 15 channels at frequencies ranging from 89 to 191GHz.Eight temperature sounding channels have center frequency at 118.75 GHz oxygen absorption line,five humidity sounding channels have center frequency at 183.31 GHz water vapor absorption line and two window channels centered at89 and 150 GHz.118 GHz channel is first used to detect atmosphere on current operational satellite.118 GHz and 183 GHz channels can obtain fine vertical distribution structure of atmosphere humidity and temperatures.These data will be used in data assimilation and climate research.Before MWHTS observationsquantitative application,the on-orbit test was carried out.The MWHTS post-launch instrument performance was conducted with on-orbit data during a period of three months.The main parameters monitored include the radiometric counts from the cold space and warm target,the warm target temperature and instrument temperature.These calibration data through quality control were converted to brightness temperature use non-linear correction and correction of antenna spill-over effects.There are three methods to validate MWHTS measurements:1.Use the atmospheric humidity and temperature profiles and surface temperatures which were observed by site calibration test in the radiance transfer model Mono RTM(Monochromatic Radiative Transfer Model)to simulating the MWHTS radiation.The difference between simulations and measurements are assessed.2.When the same kind sensors observe the same target at the same time,the observed brightness temperature difference should be the small and constant bias.The ATMS on a SNPP satellite was used to be reference sensor.The MWHTS calibration results are cross compared with ATMS by the SNO.The time gap for matched data is less than 20 minutes and the ground distance is less than 3km.The scan angle difference is less than 5degree around nadir.Spatial subsets are extracted for 3×3 MWHTS pixels for homogeneity checking,the brightness temperature standard deviation is less than the threshold of 1.0Kare qualified.3.The CRTM(Community Radiative Transfer Model)was used to simulate the brightness temperature at MWHTS channels.The input data for CRTM come from the National Centers for Environmental Prediction(NCEP)Global Data Assimilation System(GDAS).The difference between observations and simulations which to be referred as OB were analyzed.The statistic characteristics of O-B were also affected by the change of channel frequency,accuracy of radiative transfer model simulation and input profiles.The inter-satellite validation is useless for the first used channels(such as 118.75 GHz channels).The O-B characteristics were partly demonstrating the calibration accuracy of sensor.The results of post launch site calibration show that brightness temperature bias for every channel except 14 is less than 1.3 K.The brightness temperature observed by MWHTS and ATMS were compared to demonstrate the mean bias for channel 14 is the biggest than other channels and the standard deviations for five humidity sounding channels is less than 1 K.Furthermore,the differences between MWHTS observations and the forward radiativetransfer model simulations,referred to as"O-B",suggest that the standard deviations of"O-B"difference for channel 2to 6 which is near the center of 118.75 GHz oxygen absorption line is less than0.5Kand that for other channels is similar to that for corresponding ATMS channels.The scandependent biases for MWHTS indicate the temperature dependence of scan biases is noticed of channel 1,7to 13 and 15.
