Abstract: The split window statistical method for retrieval of atmospheric precipitable water is developed by GMS-5 infrared brightness temperatures measurements. The preliminary test shows that the RMS error of the method is The precision is superior to that of GOES split window retrieval method. And it not only comes up to but also is superior to that of AVHRR split window estimations. The comparison of the monthly mean precipitable water distribution shows that the retrieval U field is in good agreement with that of the conventional radiosonde observation.
