The computation results of coupled hydrological and hydrodynamic modelling application for the Nemunas River watershed – Curonian Lagoon – South-Eastern Baltic Sea continuum

The datasets provided here were used to analyse the cumulative impacts of climate change in a Nemunas River watershed – Curonian Lagoon – South‑Eastern Baltic Sea continuum by applying a state-of-the-art coupled modelling system, which consists of hydrological and hydrodynamic models.

Meteorological data used for running the models were acquired from CORDEX (Coordinated Regional Downscaling Experiment) scenarios for Europe from the Rossby Centre high-resolution regional atmospheric climate model (RCA4), which consisted of four sets of simulations (downscaling) driven by four global climate models:

Climate change scenarios and periods:

Historical/reference (1970-2005);

RCP4.5 (2005-2100);

RCP8.5 (2005-2100).

The datasets consist of time series for the parameters of:

Ice thickness - average ice thickness in the Curonian Lagoon;

Meteorological data - bias-corrected temperature and precipitation data for the marine and terrestrial areas;

Nemunas River discharge - simulated average daily values for the discharge and water temperature;

Salinity - selected points in the south-eastern Baltic Sea and one point next to Juodkrantė (in the Curonian Lagoon);

Water fluxes - through four predefined cross-sections in the Curonian Lagoon;

Water level - in 10 preselected points in the Curonian Lagoon and South-eastern Baltic Sea;

Water residence time - in the total Curonian Lagoon area, as well as its northern and southern parts;

Water temperature - in 10 preselected points in the Curonian Lagoon and South-eastern Baltic Sea.

Some of the datasets (zip files) have additional information (coordinates, data column explanations, units, etc.) in READ_ME.txt files.
