Abstract Combined with the GNSS/MET and microwave radiometer detection data of Hefei National Basic Station from 2020 to 2021,this paper calculates the specific information of atmospheric precipitation,and analyzes the change characteristics and differences of the two.The results show that the variation trends of GNSS/MET and microwave radiometer values are consistent and have a good correlation,which can better reflect the change of water vapor over Hefei area,but there are also obvious deviations.The root mean square error is the largest in summer and the smallest in winter,while the relative variance is the opposite.From the comparison,the microwave radiometer data are more representative in summer and autumn.
