Modelled nutrient emissions, loads, and concentrations in river basins of the German North Sea and Baltic Sea around 1880

The MoRE model was applied to the years around 1880 to quantify the historical emissions, loads, and concentrations of nitrogen and phosphorus for river basins discharging into the German North Sea and Baltic Sea. The historical water balance was derived with the model LARSIM-ME and integrated into MoRE. The model results complement the historical model results underlying the existing German nitrogen targets at the limnic-marine border and the good ecological status of coastal and marine waters.

The dataset file contains the geometry of the 3048 modelling units within the basins of the North Sea and Baltic Sea (excluding the Szczecin Lagoon and the upper Danube river basin) and a long, tab-delimited data table with model output and selected input data (47 variables)
