Geoclimatic factors control emissions of NO, N₂O, and N₂ from natural and managed ecosystems across a wide range of spatiotemporal scales. For example, warming can increase N emissions, with the effects of warming relevant from regional (e.g., altitudinal gradients) to global scales. Similarly, shifts in precipitation variability can influence the processes controlling N gas emissions by changing soil redox, gas diffusivity, and microbial access to N. In turn, these factors interact with land use and soil physicochemical properties to further affect N cycling rates and emissions. Untangling the influence of and interactions between these factors is key to understanding the processes driving N emissions, and thus to predict how global changes will affect future N emissions. We welcome studies investigating geoclimatic drivers of N emissions. We also encourage submissions exploring novel techniques (e.g., isotopologues) for studying NO, N₂O, and N₂ production–consumption pathways that could be used to inform geoclimatic studies.
