Abstract：The temperature and humidity of Airda-HTG4 ground-based multi-channel microwave radiometer are compared and evaluated by using Xuzhou sounding data.The results show that there is a good correlation between the microwave radiometer data and the sounding data.The correlation coefficient of temperature and humidity is above 0.8,and the correlation coefficient of temperature is 0.992.Through one case analysis,it also shows that the model equipment can well invert the temperature profile of 0~10 km height and the humidity profile of 0~5 km height.This paper can provide reference for the data application of the same type of ground-based multi-channel microwave radiometer.
