Multidecadal Sea Level Variability in the Baltic Sea and Its Impact on Acceleration Estimations
Multidecadal sea level variation in the Baltic Sea is investigated from 1900 to 2020 deploying satellite and in situ datasets. As a part of this investigation, nearly 30 years of satellite altimetry data are used to compare with tide gauge data in terms of linear trend. This, in turn, leads to valid...
