Description:
Global Positioning System (GPS) has
demonstrated its ability to monitor the atmospheric water vapor content with an accuracy comparable to other techniques and
means of measurements (e.g. radio soundings, microwave radiometers), even with good time resolution and under all meteorological conditions. The nowadays extensive use of
permanent GPS stations, operating for geodetic purposes, offers a tool for a dense and reliable remote sensing of atmospheric
water vapor. Here the tropospheric delay observed on some continuous GPS (CGPS) stations of the Italian GPS network
(RING) is analyzed and its time evolution is discussed. We focus mainly on the study of the wet component of the atmospheric
delay of the GPS signals and the computation of the precipitable water by using co-located GPS and meteorological stations. The
results are described and discussed in comparison with different meteorological observations collected during extreme weather
conditions impacting the Campania region.
