Abstract
Ground-based microwave radiometer is a new type of automatic atmospheric detection device with high precision and multi-channel. In order to investigate the reliability of detection data, this article compares and analyses the meteorological elements retrieved from microwave radiometer (MWR) and observational data from radiosonde. The results show that temperature profile and water vapour density profile from MWR have better positive correlation with those from radiosonde. The temperature retrieved from MWR is lower than that from radiosonde in non-precipitation condition, but higher in precipitation condition. The bias may be related to sampling methods, MWR retrieval methods, precipitation and so on.
