Opis
The data set contains the results of numerical modelling of sea level fluctuations in the Baltic Sea in the Baltic Sea since 1998. A long-term reanalysis was performed using a three-dimensional hydrodynamic model PM3D (Kowalewski and Kowalewska-Kalkowska, 2017), a new version of the M3D model (Kowalewski, 1997).
The model is based on the Princeton Ocean Model (POM) developed at Princeton University (Blumberg and Mellor, 1987). Like POM, the M3D/PM3D model uses the Mellor-Yamada turbulence scheme and sigma vertical coordinates. The simulation was carried out in a rectangular grid of 3' (latitude) and 6' (longitude) resolution. The spatial resolution was 3 nautical miles, i.e. about 5.5 km. An open boundary was located between the Skagerrak and the Kattegat along the parallel connecting Skagen and Göteborg, where the water exchange with the North Sea takes place. A radiation condition based on Somerfield’s concept for velocities vertically averaged and normal to the boarder plane was applied. Weather forcing since 1998 was carried out using the results of operational numerical forecasts conducted by ICM University of Warsaw using the Unified Model (UM) developed by Met Office. The PM3D model uses the assimilation of sea surface temperature from the satellite (SST) and measurements of salinity and water temperature from ships at standard depths as part of ICES monitoring.
The sea level spatial distributions were recorded in the model's computational grid in unproiected form (LatLong, WGS 84, EPSG: 4326) with an hourly time interval. Sea level values are expressed in metres relative to the mean level of the Baltic Sea in the PM3D model. The validation of the sea level modeling results for the period 2010-2015 showed (Kowalewski and Kowalewska-Kalkowska, 2017) a root mean square error (RMSE) of 8 to 13 cm for various stations in the Baltic Sea.
