Abstract | Atmospheric deposition of particulate organic nitrogen (ONp) is a significant process in the global nitrogen cycle and may be pivotally important for N-limited ecosystems. However, past models largely overlooked the spatial and chemical inhomogeneity of atmospheric ONp and were thus deficient in assessing global ONp impacts. We constructed a comprehensive global model of atmospheric gaseous and particulate organic nitrogen (ON), including latest knowledge on emissions and secondary formations. Using this model, we simulated global atmospheric ONp abundances consistent with observations. Our estimated global atmospheric ON deposition was 26 Tg N yr^−1, predominantly in the form of ONp (23 Tg N yr^−1) and mostly from wildfires (37%), oceans (22%), and aqueous productions (17%). Globally, ONp contributed as high as 40% to 80% of the total N deposition downwind of biomass burning regions. Atmospheric ONp deposition thus constituted the dominant external N supply to the N-limited boreal forests, tundras, and the Arctic Ocean, and its importance may amplify in a future warming climate.
