A new map product for calculating the critical loads for eutrophication and acidification of terrestrial ecosystems and for modelling air quality was created in this project. The spatial extent of the map covers a large number of countries in Europe, the Caucasus and Central Asia. The results of this project are map products representing the land cover in 217 EUNIS classes and 13 RCG classes. In addition to the individual, national application of the data set, a broader use of the data is planned within the framework of the Convention on Long-Range Transboundary Air Pollution.
