The rapidly changing greenhouse gas budget of Asia



International Workshop on Asian Greenhouse Gases Budgets; Ahmedabad, India, 27–29 September 2011 An international workshop assessed the availability of data and modeling capability to work toward the establishment of the greenhouse gas (GHG) budget for South and Southeast Asia. The workshop was organized with support from the Asia-Pacific Network (APN) and the Indian Space Research Organisation Geosphere-Biosphere Programme at the Physical Research Laboratory, in Ahmedabad, India. The effort is based on the synthesis and reconciliation of top-down (atmospheric observations and inverse models) and bottom-up estimates (ground-based fux observations and terrestrial models). While inverse estimates provide a regional net GHG balance, bottomup estimates provide the necessary process attribution to shed light into future dynamics and the components of the balance that can be managed by human activity.
