Vertical displacement time series from GNSS stations in the Po river basin area

ASCII files reporting the daily GNSS vertical ground displacement time series, in the Eurasia-fixed reference frame, of continuous stations located in the Po river basin. The time series are obtained by analyzing the raw GPS observations using the GAMIT/GLOBK (version 10.71) software, following the standard procedures of the repro2 IGS reprocessing scheme (http://acc.igs.org/reprocess2.html). This is part of a large processing effort, including>4000 stations in the Euro- Mediterranean and African regions (Serpelloni et al., 2022), where sub-networks, made up of <50 stations dynamically and optimally selected based on daily data availability, are processed independently with GAMIT and later tied together using common sub-net tie sites and IGb14 core stations using the GLOBK software. This time series are used to study the effect of the 2021-2022 drought occurred in Northern Italy. The four columns of the files represent the epoch (in decimal years), the displacement in the Up component (in mm), longitude of the station (°) and latitude of the station (°).
