RIVM has published the 2021 large-scale concentration and deposition maps

The National Institute for Public Health and the Environment (of the Netherlands) has published the 2021 large-scale concentration and deposition maps

Concentration maps show airborne pollutants such as #nitrogen dioxide, #ammonia and #fine dust. It is good to know that these concentrations are slowly but more or less continuously decreasing.
