摘要:
Precipitable Water Vapour (PWV), one of the parameters defining an instant state of troposphere, can be derived from the combination of GPS observations and ground meteorological measurements. The precision of the PWV values depends on many variables used in the computation. Their influence is discussed and analysed. The accuracy of the GPS based PWV values is estimated by comparison to the radiosonde based PWV values within the period 2004-2007. Due to different behaviour of the PWV with respect to time of the year, the analysis is performed in each season separately.
