Short summary
Within the EU COST Action ES1206 we have studied the horizontal variability of the atmosphere using signals from GPS satellites, distant quasars, and a microwave radiometer. We find a consistent picture: horizontal variability over timescales of months are mainly due to atmospheric pressure, whereas water vapour is the main cause of variations over times from minutes to hours. An understanding of these variations helps to improve the accuracy of GPS applications in both geodesy and meteorology.
