The RECCAP-2 team hosted a session at the 2019 Fall American Geophysical Union (AGU) Meeting in San Francisco by DWD and Spectral Earth, which took place from 9-13 December 2019.

This session aimed 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.
