Improving Bottom-up Emissions Information Based on Air Quality Measurement and Modeling Feedbacks - The KORUS Emissions Inventory

Air quality over the Northeast Asia region has been deteriorated despite of more stringent air pollution control policies by the governments. The needs of more scientific understanding of inter-relationship among emissions, transport, chemistry over the region are much higher to effectively protect public health and ecosystems. Two aircraft filed campaigns targeting year 2016, MAPS-Seoul and KORUS-AQ, have been organized to study the air quality of over Korea and East Asia relating to chemical evolution, emission inventories, trans-boundary contribution, and satellite application. We developed a new East-Asia emissions inventory, named KORUS version 1.0, based on NIER/KU-CREATE (Comprehensive Regional Emissions inventory for Atmospheric Transport Experiment), in support of the filed campaigns. For anthropogenic emissions, it has 54 fuel classes, 201 sub-sectors and 13 pollutants, including CO₂, SO₂, NO_x, CO, NMVOC, NH₃, PM₁₀, and PM_2.5. During and after the field campaigns, we are providing modeling emissions inventory to participating air quality modeling systems. Based on initial and follow-up assessment of those results, the bottom-up emissions inventory has been improved based on the feedbacks from measurement and modeling communities. The features and performances of the latest version - version 2.1, will be presented at the conference.
