There is an increase in number of observational platforms, such as satellites, aircrafts, ships, and ground stations, for monitoring atmospheric greenhouse gases (GHGs) and air pollutions. National or regional inventories of emissions have also been prepared at greater resolution in space and time. However, due to uncertainties in modeling tools, and limited observational data coverage, high uncertainty still remains in global or regional sources/sinks estimations.
Developing integrated observation and analysis systems for GHGs are the most urgent tasks and it is understood that short-lived air pollutants plays critical role in cycling of GHGs as defined by the United Nations Framework Convention on Climate Change (UNFCCC). Therefore atmospheric transport modeling, inverse modeling, and assimilation methods should be tested and improved for process level understanding of regional fluxes of GHGs as well as the air pollutants. All results should be complemented by the both "top-down" approach (with inverse models) and "bottom-up" approach (with surface flux/emission network data and ground-based models).
The purpose of the session is to discuss state-of-the-art techniques for estimations of surface emission of GHGs and air pollutants. Ideally these results should allow us to detect any changes that might be appearing globally and in the Asia-Pacific under the changing climate, and to disseminate scientific knowledge for developing emission mitigation policies in timely manner. Improved estimates of emissions from land use change, fires, and other anthropogenic sources (urban and thermal power station, etc.) should be addressed. We also welcome discussions for designs and plans for future studies targeting city and country scale emission issues using sophisticated modeling tools for improved understanding human impacts on future climate change.
