| Session Description | The Korea-United States Air Quality Study conducted in and around the Republic of Korea during May-June 2016 provided a comprehensive set of measurements from ground sites, multiple instrumented aircraft, and satellites. The study was designed to identify the factors governing ozone photochemistry and aerosol evolution in a modern megacity and in surrounding rural areas, including local anthropogenic and biogenic emission sources and also upwind influences from East Asia, and to better understand the connections between this region and the larger global atmosphere. KORUS-AQ data will improve capability for satellite remote sensing of air quality in preparation for launches of the first geostationary air quality missions later this decade, GEMS (KARI) and TEMPO (NASA), and also allow evaluation and improvement of air quality models. Providing a greater regional context, related efforts included an airborne campaign in China’s Hebei province upwind of KORUS-AQ and ground-based activities in Japan downwind. This session invites contributions related to all aspects of these field studies as well as preparatory campaigns such as the 2015 MAPS-Seoul study. Topics may include analysis of the in-situ and remote-sensing measurements and comparisons with measurements from other campaigns, meteorological and chemical modeling analyses and developments, remote sensing retrieval algorithm developments, advances in data assimilation, and assessing societal impacts of pollution. Overall this session seeks to advance the scientific understanding and community building needed to ensure the future success of the integrated observing system for air quality that is within reach later this decade. |
