Polar and Wintertime Atmospheric Chemistry
Polar and Wintertime Atmospheric Chemistry
Session ID#: 158403
Session Description:
Recent studies are tackling the significant and critical knowledge gaps that exist in understanding atmospheric chemical mechanisms that occur at low temperatures (in the presence of snow/ice), and often dark conditions, in both pristine and populated (including wintertime mid-latitude) locations. Polar regions are experiencing climate change that is transforming ecosystems with sea ice loss, driving population growth, and increasing resource extraction and transportation, thereby altering emissions of gases and particles. Improved understanding of chemical processes over snow and ice and in presence of clouds is critically important for both air quality and climate.
This session invites contributions from field, modeling, and laboratory studies investigating atmospheric chemistry occurring in Polar (Arctic & Antarctic) and wintertime mid-latitude regions. This includes studies of atmospheric gases, aerosols, aerosol-cloud interactions, and atmosphere-snow/ice interactions. As an example, results from the 2022 Alaskan Layered Pollution And Chemical Analysis (ALPACA) campaign, in polluted, snow-covered Fairbanks, Alaska, are encouraged.
