| Session Description | Over the past two decades, global satellite remote sensing has increasingly been used to characterize and forecast surface air quality and related quantities. Most of these techniques are dependent on polar-orbiting sensors, which typically sample locations at most once a day. This limits our ability to understand the diurnal cycle of gases and aerosols, as well as clouds that provide wet deposition/scavenging pathways and impact tropospheric photochemistry by modifying solar radiation. Likewise, this limits our understanding of the impact of diurnally-dependent sources (e.g., fires, dust storms, industry, transportation, etc.), meteorology and chemistry. However, with the recent deployment of advanced sensors in geostationary orbit (GOES-16, Himawari 8/9, GOCI, etc.) and many more to be launched in the near future (TEMPO, GEMS, FCI, GISAT), there is a huge opportunity to break this temporal barrier. In fact, with so many new sensors coming online, we envision a constellation of such sensors to help monitor, characterize and forecast global air quality, aerosols and clouds. With this opportunity come challenges. We welcome presentations on all aspects of such geostationary efforts, including satellite retrievals and products, their use for characterizing climatologies, transport (dust, smoke, volcanic, urban pollution) and processes, their synergy and fusion with other existing observations, and modeling and assimilation efforts. Studies focusing on geostationary observations in support of field campaigns are also welcome.We also would like to extend the call for abstracts on aerosols and cloud properties retrievals and data applications from beyond Geo orbits, specifically from EPIC sensor aboard DSCOVR satellite in L1 orbit. |
