Precipitation acidity data for the Northern Hemisphere, 2000-2021

This data integrates precipitation pH and acid deposition data from four Northern Hemisphere sedimentation networks. The data allow for the quantification of the rate of change of precipitation acidification in the Northern Hemisphere. At the same time, the data are collocated with global pollutant emissions, which makes it possible to quantify the contribution of pollutants from different emission sources to the reduction of precipitation acidification.
