Fractional contributions of (a) c-NH3 (mainly from coal combustion (Cc), vehicle exhausts (Ve) and biomass burning (Bb)) and v-NH3 (mainly from fertilizer application (Fa) and wastes (Wa)) emission sources to atmospheric NHx deposition, (b) f-NOx (mainly from coal combustion (Cc) and vehicle exhausts (Ve)) and nf-NOx (mainly from biomass burning (Bb) and microbial N cycles (Mc)) emission sources to atmospheric NOy deposition at Mengshan in 2012, 2018 and 2022. Mean ± SD is shown.
