Reprocessed IWV data from ground-based GNSS network during EUREC4A campaign

<p>Integrated Water Vapour (IWV) data were retrieved from the measurements of nearly fifty permanent GNSS stations in the Carribean region and two special station that were installed at the Barbados Could Observatory (BCO) facilities at the end of 2019. The measurements were processed offline with Gipsy-Oasis II v6.4 software in Precise Point Positioning (PPP) mode. The ZTD estimates were screened for outliers and converted using ERA5 surface pressure and weighted mean temperature derived from the 1-hourly pressure-level data interpolated to the 5 min temporal resolution of the ZTD data. The final IWV data are provided with a 5 min sampling for the period from 1 January to 29 February 2020. </p>
