BG1.7

Anthropogenic disturbance of the nitrogen (N) cycle has more than doubled the amount of reactive N circulating in the biosphere. Exchange of nitrogen gases between land and atmosphere are strongly affecting Earth’s atmospheric composition, air quality, climate change and human health. This session seeks to improve our understanding on how global changes impact N biogeochemistry in terrestrial and aquatic ecosystems and what atmospheric interactions will be most important in influencing the climate. We seek to link microbiological nitrogen processes and surface nitrogen gases flux with ecosystem dynamics, air quality and atmospheric chemistry. We will cover fluxes of various nitrogen gases and the underlying transformation processes in soils and sediments, e.g., fixing of atmospheric dinitrogen, release of nitrous acid (HONO), nitric oxide (NO), nitrogen dioxide (NO2), nitrous oxide (N2O) and ammonia (NH3) as well as interactions with ozone, volatile organic compounds, free radicals as well as aerosols in the atmosphere, and further impact on air quality. Further, the interactions of N cycling with other element cycles (e.g., carbon, phosphorus) in ecosystems and terrestrial-aquatic linkages, and feedbacks to biodiversity loss and water pollution will be explored. We welcome a wide range of studies including methods development and application of new devices, observational, experimental, and modeling approaches.
