Absolute sea level changes at the tide gauge station in Władysławowo using different time series software packages
This paper presents geocentric sea level changes at the tide gauge station in Władysławowo, Poland. These changes have been calculated from the time series of GNSS and tide gauge observations. For the estimation of the geocentric sea level trend computer software packages Hector, GITSA, GGMatlab, and Statistica have been used. The results show that all the software packages give a similar value of absolute sea level changes in Władysławowo and it is estimated at a rate of around 3 mm/year.
