Regional budgets, trends and drivers of major greenhouse gases (N2O, CH4 and CO2)

Session ID#: 78425

Session Description:
The Paris Agreement on Climate sets the international objective to keep climate warming well below two degrees. This extraordinary challenge requires a dramatic improvement of current scientific capabilities to estimate the budgets and their trends of greenhouse gases (GHG) at regional scale, and how they link up to the global growth rates of the major GHGs (N2O, CH4 and CO2). This session aims to bring together studies to help understand and quantify regional budgets, trends and variability, and drivers of major GHG (N2O, CH4 and CO2) through the analyses of emissions inventories, field and remotely-sensed observations, terrestrial and ocean biogeochemical modeling, and atmospheric inverse modeling. Abstracts using any of these methods or their combination and approaches at multi-scales from regional to global are invited. We encourage research from this session to contribute to the REgional Carbon Cycle Assessment and Processes (RECCAP2), a new global assessment of the Global Carbon Project.
