Under the heading of the OSPAR convention (Sect. 1.1), the IGC-EMO database of daily freshwater inflows and nutrient loads was compiled by van Leeuwen and Lenhart (2021), which covers the major rivers discharging into the Baltic Sea, North Sea and Northeast Atlantic (Sect. 1.2). In this database, the data are distributed in separate ASCII files according to the respective country and river. In order to allow an easier utilization within a regional Earth System or ocean modelling framework, we mapped the IGC-EMO data onto the flow grid of the European 1/12° domain of the Hydrological Discharge (HD) model (Sect. 1.3). This mapping was done for daily time series of discharge, total nitrogen (N), total phosphorus (P) and Silicate for the period 1940-2022 following the procedure described in Sect. 1.4.
