The National Astronomical Research Institute of Thailand (NARIT) has recently began to establish the National Research Center for Atmospheric Science (October 2016 – present). It focuses on studying: (1) space weather impact on Earth’s climate and the upper atmosphere; (2) impacts of the lower atmosphere on the upper atmosphere and vice versa; and (3) effects of greenhouse gases, air pollutants and aerosols on climate, weather and health. In this talk, initial research on air pollutant concentrations will be presented, specifically: (1) non-chemistry coupled modeling of PM10 over Chiang Mai, Northern Thailand; (2) chemistry coupled modeling of air pollutants over Thailand; (3) planetary boundary layer height temporal evolution and its relation to PM10 and PM2.5 concentrations. A potential aircraft campaign over the South/Southeast Asian region will also be discussed.
