RESUMO:

The Zenithal Tropospheric Delay (ZTD) stands out as one of most important factors that influence artificial satellite positioning of GNSS  (Global Navigation Satellite System), It is basically the sum of two components: the hydrostatic effect (ZHD – Zenithal Hydrostatic Delay) which is predominantly influenced by nitrogen and oxigen present in the atmosphere, and the wet component (ZWD – Zenithal Wet Delay),  strongly influenced by water vapor in the troposphere. Both components can be calculated from GNNS gauge station observations.   Moreover the ZWD component is nearly related with the IWV (Integrated Water Vapor) in the atmosphere, a parameter that is directly related to the tropospheric precipitable water vapor. This study aims to develop a software that enables generate a database of IWV obtained from radiofrequency signals of any GNSS gauge station, and relate them with oceanic surface variables. Among others, this  software is able to generate time series and maps of spatial distribution of the variables, beside statistical treatments of results such as imputations and correlations techniques.   Tests with good results were carried out using data from GNSS-RNNA and the Meteorological Natal-A304 gauge stations, both in Natal (RN), Brazil, localized on the campus of UFRN.
