The principle and method of remote sensing precipitable water (PW) by the Global Positioning System (GPS) are introduced. A series of tropospheric delay have been obtained from the dual frequency rece
The geopotential variation caused by solid Earth, ocean and atmospheric tides can be estimated from artificial satellite orbit perturbations. It is shown that the total tidal variation in geopotential
Through GPS carrier phases observation in southwestern China during 1991-1997,the velocity field within eastern Qinghai-Xizang (Tibet) and its neighbour regions has been es-tablished. The velocity of
Remote sensing (RS) of land surface temperature (LST) is a very challenging problem at the present development stage of RS science. Tremendous efforts have been devoted to atmosphere correction and te
