Fig. 1: Temporal trends in NHx deposition and precursor emissions over China from 1980 to 2015.
From: Precipitation trend increases the contribution of dry reduced nitrogen deposition
a Deposition flux (kg N ha−1 yr−1) and the ratio of dry to wet NHx deposition (\({R}_{{\rm{NH}}x({\rm{dry/wet}})}\)). b Anthropogenic emissions of SO2, NOx, and NH3 (Tg yr−1) (data obtained from Yu et al.16); circles represent the average modeled dry deposition, measured wet deposition, total deposition (dry + wet), and emissions for a given time period; the dashed lines are a linear fit to the points; gray bars are \({R}_{{\rm{NH}}x({\rm{dry/wet}})}\) and are plotted on the right-hand axis; error bars indicate standard deviation (s.d.).
