Description
SSiRC is an established SPARC (Stratosphere-Troposphere Processes and their role in Climate) activity, with SPARC being a core project within the World Climate Research Program (WCRP).
May 2022 SSiRC workshop (Univ. Leeds, U.K.)
The workshop will be held 16th to 18th May 2022 at the University of Leeds (originally planned for 28th to 30th March 2022, postponed due to omicron wave)
Stratospheric Sulfur and its Role in Climate (SSiRC) The overarching aim of SSiRC is to foster collaboration across observational and modelling groups to better understand the stratospheric aerosol layer and the drivers for its observed variations.Outside of volcanic periods, the layer is an optically thin veil of aerosol, with a small but well characterized impact on climate, but after explosive volcanic eruptions, it intensifies dramatically. Such abrupt volcanic enhancements of the stratospheric aerosol concentrations cause strong solar dimming and thereby surface cooling with important changes in circulation and atmospheric composition in response.
The meeting’s focus will be on observations and modelling of the stratospheric aerosol layer and its sources and, particularly, to understand volcanic impacts on stratospheric composition and climate.
There are 6 specific themes for the May 2022 SSiRC workshop:
• Measurements and modelling re: the Jan 2022 Hunga-Tonga eruption
• Stratospheric aerosol from intense wildfires and other recent eruptions (e.g., Raikoke).
• Observations or model case studies re: field campaigns (e.g. StratoClim, AToM and ASPEN).
• Studies aligned with community modelling activities (e.g. ISA-MIP, VolMIP and GeoMIP).
• Research from related science programs (e.g. OCTAV-UTLS, CCMI, PAGES and VICS).
• Measurements and modelling of non-sulfate aerosol and aerosol precursors such as SO2, OCS.
