CATCH proudly announces the next Open Science Workshop 9-13 May 2022 to discuss atmospheric chemistry research, with a focus on natural processes specific to cold regions of the Earth.
The workshop hosted invited talks recordings of which you may still download from this webpage. Follow the session links below for a detailed list of available talks. You also find links to the Question & Answer discussions that took place along with the talks.
Day 1 - 9 May: Linking biogeochemistry to aerosol-cloud interactions in the Southern Ocean and Antarctic (Marc Mallet & Ruhi Humphries & Sonya Fiddes):
Present PICCAASO key science questions and plans, engage community members that can contribute. Download Discussion Notes
Day 2 - 10 May: Ocean-ice-snow-atmosphere fluxes (Markus Frey & Jen Murphy): Presentation of the current approaches to quantify trace gas and aerosol fluxes above ocean, ice and snow surfaces. Discussion of the strategies to overcome limitations/uncertainties in measurement strategies and how to use this flux information within models. Download Discussion Notes
Day 3 - 11 May: Polar halogen chemistry and interlinked processes (Jennie Thomas & Thorsten Bartels-Rauch): What is the role of snow, including snow on sea ice, compared to sea salt aerosols in activating and sustaining halogen chemistry? What are the main outstanding questions regarding how halogens influence atmospheric aerosols and oxidation capacity? Download Discussion Notes
Day 4 - 12 May: Cryospheric links to aerosol-cloud interactions (Paul Zieger & Jessie Creamean): What are the sources and abundances of cloud forming aerosols in the polar regions and how do these vary over the seasons? What processes control aerosol emission and transport? What are the current modeling deficiencies? Download Discussion Notes
Day 5 - 13 May: Coupling of ocean-ice-atmosphere processes: from sea-Ice biogeochemistry to aerosols and Clouds, SCOR WG #163: CIce2Clouds (Megan Willis & Nadja Steiner): Present educational sessions on cross-cutting themes that link the sea-ice/ocean/atmosphere system. Present the plans for CIce2Clouds, and first steps from sub-working groups, to the community and engage community participation. Download Discussion Notes
