Correction to: Dissecting the contributions of organic nitrogen aerosols to global atmospheric nitrogen deposition and implications for ecosystems

In the article by Li et al., ‘Dissecting the contributions of organic nitrogen aerosols to global atmospheric nitrogen deposition and implications for ecosystems’, National Science Review 2023; 10: nwad244, https://doi.org/10.1093/nsr/nwad244, errors were identified concerning Fig. 4G, Table 1 and the corresponding values in the text. The specific corrections are as follows: Global atmospheric burden of ON: Our original calculation did not properly account for the vertical variation of air density, leading to an overestimation of the ON burden (Column 2 in Table 1). We correct by using the correct air density profile. Imine secondary organic nitrogen (SON) formation: In the original version, we calculated imine SON formation assuming constant reactant abundance. We update this calculation by using pseudo-first-order rate constants, where ammonium (NH₄⁺) is assumed constant, while glyoxal and methylglyoxal decrease over timesteps. Simulated annual mean atmospheric deposition fluxes of ONp from different sources. (A) anthropogenic PONp; (B) biomass burning PONp; (C) fine dust PONp; (D) fine marine PONp; (E) fine biogenic PONp; (F) ship-emitted PONp; (G) imine SONp; (H) organic nitrate SONp; (I) nitroaromatic SONp; (J) coarse dust PONp; (K) coarse marine PONp; (L) coarse biogenic PONp. Global budget of atmospheric ON and the ON : TN ratios in atmospheric deposition as simulated by the GEOS-Chem model. Global budget of atmospheric ON and the ON : TN ratios in atmospheric deposition as simulated by the GEOS-Chem model. The corrected Table 1 and corresponding text are presented below. Corrections involve the values of atmospheric burden (second column from left in Table 1, and those in the main text; both highlighted in bold). Table 1 summarizes the global budget of atmospheric ON as simulated by our model. The total atmospheric burden of ON was 0.4 Tg N (range in sensitivity experiments was 0.26 Tg N to 0.56 Tg N), including 0.2 Tg N of ONg and 0.2 Tg N of ONp. ONg species were mostly chemically produced in the atmosphere as acyl peroxy nitrates (e.g. peroxyacetyl nitrate) and non-acyl peroxy nitrates (e.g. methyl peroxy nitrate), and all ONg species had limited solubility [2]. As such, ONg were mainly removed from the atmosphere by thermal decomposition, photolysis or OH oxidation [26,60], with deposition accounting for a mere 1% to 2% of its global sink [61]. Globally, ONg only constituted 9% of the total atmospheric ON deposition. In contrast, ONp constituted only 50% of the global atmospheric ON burden but dominated the global atmospheric ON deposition (91%). Of the 0.2 Tg N global atmospheric ONp burden, 87% (0.18 Tg N) was in the fine mode (ONfp). ONcp constituted only 13% (0.03 Tg N) of the global ONp burden because of its rapid deposition. The corrected Fig. 4 is presented below. There is a slight difference in Fig. 4G while the other sub-figures remain unchanged.
