The paper uses TRMM/TMI data to quantitatively analyze the relationship between precipitation(P) and water vapor path(W),Latent Heat(LH) of tropic cyclones over the Northwest Pacific Ocean.

Study on the atmospheric water vapor from MODIS image;

Based on the solar radiation observations from CE-318 sun-photometer s 936 nm channel and the relation of water vapor amount and transmissivity,the instantaneous technique is used to retrieve the atmospheric column water vapor amount on the west coast of the Bohai sea gulf.

Characteristics of average water vapor content in the atmosphere in Yangtze-Huaihe region and its variation;

MODIS-based reversion of atmospheric water vapor content over Jinta Oasis;

The results show that the atmospheric water vapor content continuously decreased from the early 1960s to the middle of 1980s, then a little increase occurred after the middle of 1980s, however after the middle of 1990s, the atmospheric water vapor content again decreased and was close to the lowest level in the history at the early 21~(th) century.

This paper introduces the theory of remote sensing precipitable water vapor by using global position system ,the precipitable water vapor be calculated by GPS date and meteorologic date in Harbin area, the datashow:the results of precipitable water vapor by GPS compare to the results of precipitable water vapor by radio sound can attain the precision of mm.
