Short summary
Ground-based observations of precipitation chemistry over China, Korea, and Japan from 2001 to 2015 were compiled, and the ratio of nitrate to non-sea-salt sulfate concentration in precipitation was analyzed to identify the long-term record of acidifying species. The variations in the ratio in East Asia corresponded to the NOx / SO2 emission ratio and the NO2 / SO2 column ratio in China. The results indicated that the acidity of precipitation shifted from sulfur to nitrogen.
