Applying the Water Vapor Radiometer to Verify the Precipitable Water Vapor Measured by GPS
Terrestrial, Atmospheric and Oceanic Sciences, 2014 Taiwan is located at the land-sea interface in a subtropical region. Because the climate is warm and moist year round, there is a large and highly variable amount of water vapor in the atmosphere.

Estimation of Precipitable Water Vapor Using the GPS [PDF]
Journal of Astronomy and Space Sciences, 1999 The radio waves transmitted from GPS satellites is delayed by the troposphere as they propagate to Earth-based GPS receivers. The troposphere delay is usually divided into two parts, the dry delay due to the atmospheric gases and the wet delay due to the

Retrieval of the change of precipitable water vapor by GPS technique [PDF]
Geo-Spatial Information Science, 2007 The feasibility of GPS precipitable water vapor (PWV) is discussed based on the comparison of Radiosonde and GPS PWV where the correlation coefficient is 0.94 and the RMS is 4.0 mm. PWV change in the Chinese mainland in 2004 is graphed with the gridding method of splines in tension, according to the GPS data of the crust monitor observation network in ...
