Opis
The dataset contains the results of numerical modeling of water temperature and salinity in the Baltic Sea since 1998. A long-term reanalysis was performed using the three-dimensional hydrodynamic model PM3D (Kowalewski and Kowalewska-Kalkowska, 2017), a new version of the M3D model (Kowalewski, 1997). A numerical dynamic-thermodynamic model of sea ice (Herman et al. 2011) was coupled to the analysis of ice conditions variability.
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 spatial distribution of water temperature and salinity was recorded twice a day, at a depth of 0 m, 5 m, 10 m, 15 m, 20 m, 30 m, 40 m, 50 m and 60 m in the model's computational grid in unproiected form (LatLong, WGS 84, EPSG: 4326). The validation of the modeling results for the period 1958-2007 showed a root mean square error (RMSE) of the water temperature from 0.9 to 1.4 °C, and in the case of salinity RMSE was from 0.16 to 0.5 psu for various stations in the Baltic Sea (Jędrasik i Kowalewski, 2019).
