The Applied Study on Retrievals of Precipitable Water from the GMS-5 "Split Window"

Abstract:

Based on the radiation transfer equation and a optimized retrieval method proposed by Dennis Chesters et al., this paper describes the general formula of retrieving precipitable water(PW) by the different absorption in the split channel. The feasibility of using radiosonde observations or ground based water vapor radiometer to calibrate the absorption coefficients is researched, and the field of PW is retrieved with the coefficients.
