Ground-based GPS networks for remote sensing of the atmospheric water vapour content: a review

Övrigt konferensbidrag, 2013

The variability in the atmospheric water vapour content is an important parameter both for operational weather forecasting and climate research. In this presentation I will first describe the interplay between the atmosphere and the accuracy of the estimated positions and vectors that can be obtained in space geodesy. Thereafter, I will focus on how the efforts to model the atmospheric influence on space geodetic measurements led to the application of measuring the water vapour content of the atmosphere. Two major applications have been seen so far: close to real time analyses for use of data in weather forecasting, and (2) the long term application of climate monitoring.
