Geoclimatic factors control emissions of N₂O, NO, and other N gases from natural and managed ecosystems across a wide range of spatiotemporal scales. For example, increasing temperatures often enhance N gas emissions, with effects relevant at regional scales (e.g., altitudinal gradients) facilitating prediction of climate change-emission feedbacks. Shifts in precipitation influence N gas emissions by changing soil redox potential, gas diffusivity, and microbial activities. These factors interact with land use, microbial communities, 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 N emissions through the Anthropocene.

We welcome contributions investigating geoclimatic drivers of N gas emissions. We also encourage submissions exploring novel techniques for studying N₂O and NO production–consumption pathways that could be used to inform future geoclimatic studies.
