Abstract:Using interpolation and Z files, we study the precipitable water vapor (PWV) value, calculated by ground-based GPS with missing meteorological data. We compare the effects of different ways to select the appropriate method of PWV retrieval by ground-based GPS with missing meteorological data. The results show that interpolation of meteorological data in long periods using spline is appropriate; interpolation of meteorological data in short periods using singular spectrum analysis is appropriate. Using Z files is a good way to calculate PWV when the missing data accounts for a larger proportion of the original data.
