A physical retrieval method of total precipitable water (TPW) by GMS-5 satellite infrared-split window channels and MODTRAN radiative transfer model was developed.

The NCEP and MODIS data of 8 days in 4 months (January,April,July and October) of different seasons are used in this paper to estimate the atmospheric precipitable water over China.

Using the NCEP/NCAR monthly reanalyzed data ,the vapor resource over Zhejiang province is studied,of which include the interannual change of Precipitable water,vertical distribution characters of Precipitable water,the time and space distribution of water vapour flux,the water vapor convergence and the water vapor passage , the interannual change of net water vapor flux.

5°) from 1948 to 2007,this paper analyzed the long-term mean characteristics and the seasonal,annual and decadal variations of precipitable water in Sichuan in recent 60 years.

Using NCAR/NCEP reanalysis data on wind fields,specific humidity fields and surface pressure fields from 1954 to 2004,month by month atmosphere precipitable water was calculated in the Northwest China,then its intra-annual inhomogeneity was analyzed in terms of the concentration degree and concentration period.

The atmosphere precipitable water and vapor flux in Northwest China is abundant in the region of East Asian monsoon,followed by the region of westerly belt,and then the region of plateau.

Atmospheric Precipitable Water Amount Retrieval and Its Preliminary Study UsingGround-based GPS Data;

Using the daily NCEP/NCAR reanalysis data from 1961 to 2000,the features and variation trends of seasonal atmospheric precipitable water(APW) over Xinjiang region are analyzed.
