An Extracting Process of the Retrieval Coefficients for Three Frequency Channel Microwave Radiometer

This paper focuses on the coefficients in the retrieval model of wet troposphere path delay. The kind of microwave radiometers with three frequency channels, such as TOPEX/Poseidon microwave radiometer (TMR) and Jason-1 microwave radiometer (JMR), is discussed. A process of extracting these retrieval coefficients from the data of bright temperature and relevant physical quantities is presented. The data of JMR are used to extract the retrieval coefficients and validate this extracting process. A good agreement is shown between the data retrieved with the retrieval coefficients and the data of JMR.
