B11B:
Closing the Global Nitrous Oxide Budget: Magnitude, Spatiotemporal Patterns, and Responses I Posters


Session ID#: 10301

Session Description:
Atmospheric mixing ratios of nitrous oxide (N2O) substantially increased since the preindustrial era. Understanding the sources and magnitude of N2O as well as their historical responses to natural and anthropogenic driving forces is the key to effectively mitigate N2O emissions and climate change. This session aims at bringing together studies quantifying and predicting N2O emissions through the analysis of existing emissions inventories, empirical/statistical modeling, atmospheric inverse modeling and process-based ecosystem modeling. The objective of the session is to better constrain global and regional N2O budgets, understand the underlying mechanisms of spatiotemporal variations, and evaluate potential mitigation practices. Abstracts using observations and modeling at multiple spatial and temporal scales are invited.
