Fig. 2: Long-term trends of the historical (1980–2015) and predicted (2030–2100) precipitation scavenging index (PSI) in China.
From: Precipitation trend increases the contribution of dry reduced nitrogen deposition

Predicted PSI was calculated by using the meteorological parameters from the two global future climate change scenarios RCP 4.5 and RCP 8.5. Error bars indicate 1/3 standard deviation (s.d.).
