Coastal regions have historically represented a significant challenge for air quality investigations due to water–land boundary transition characteristics and a scarcity of measurements available over water. Prior studies have identified the formation of high levels of ozone and other air pollutants over water bodies within the United States and in other countries that can potentially recirculate back over land to significantly impact populated areas; however, large uncertainties persist. Both Earth observing satellites and forecast models face challenges in capturing the coastal transition zone where small-scale meteorological dynamics are complex, and large changes in pollutants can occur on very short spatial and temporal scales. Accordingly, this session invites authors to submit original research using recent field observations, chemical transport modeling simulations, and/or improvements in satellite retrievals within the complex coastal environment. This session invites observational research that consists of, but is not limited to, remotely sensed and in situ observations of air quality from ground-based, airborne (both manned and unmanned) and shipborne platforms. Research projects using chemical transport simulations are also invited to the session, with a specific emphasis on research that couples simulations and observations to more fully characterize land–water interaction. Authors are also invited to submit research projects that investigate current and future satellite investigations of coastal environments from space-based platforms.
