Subject: CATCH newsletter: November 2017
Introducing the CATCH Logo | | | | Our mission is to facilitate atmospheric chemistry research within the international community, with a focus on natural processes specific to cold regions of the Earth. Our new logo highlights the diversity of cold regions, which include areas which are seasonally or permanently covered by snow and ice, from the high mountains to the polar ice sheets and sea ice zones as well as regions where ice clouds that undergo chemistry are found. You can find our logo in this newsletter and on the CATCH website. | | Where to Find CATCH Science | | | | AGU Fall Meeting
11 - 15 December 2017 in New Orleans, USA
Relevant Sessions Include: - Tropospheric Composition in Cold Environments: Sources, Processes and Impacts I & II (A13O/A11K)
-
Polar Atmospheric Processes and Their Interactions with the Land, Ice, and Ocean Surface I & II (A54D/A51E) 14th Physics and Chemistry of Ice Conference 8 - 12 January 2018 in Zürich, Switzerland Link to conference program Registration closes 30 November 2017 - Register here! Last minute abstracts for posters will be accepted until 30 November 2017 | | Upcoming Community Events | | | Boundary Layers and High Latitudes (AS2.3)
Convener: Günther Heinemann Co-conveners: Thorsten Bartels-Rausch, Christopher Cox, Anna Jones, William Neff, Thomas Spengler, Argentini Stefania, Jennie L. Thomas, Michael Tjernström
This session is intended to provide an interdisciplinary forum to bring together researchers working in the area of boundary layer processes and high-latitude weather and climate (including snow physics, air/snow chemistry, and oceanography). Cryosphere and Atmospheric Chemistry processes (the focus of CATCH) are highly relevant to this session. We invite contributions e.g. in the following areas: - Observations and research on the energy balance, physical and chemical exchange processes, and atmosphere-ocean-ice (AOI) interactions including particle sources.
- Results from high-elevation sites where similar processes occur over snow and ice.
- Field programs, laboratory studies and observational studies (including remote sensing).
- Model studies and reanalyses.
- Advances in observing technology.
- External controls on the boundary layer such as clouds, aerosols, radiation.
- Teleconnections between the polar regions and mid-latitudes resulting in effects related to atmosphere-ice-ocean interactions as well as insights provided by monitoring of water vapor isotopes that shed light on air mass origins.
Halogens in the Troposphere (AS3.21)
Convener: Alfonso Saiz-Lopez
Co-conveners: Ulrich Platt, Rolf Sander, Nicole Bobrowski
Evidence is accumulating that reactive halogen species can have an important influence on the chemistry of the lower and the free troposphere. We invite contributions in the following areas dealing with halogens on local, regional, and global scales: - Model studies: Investigations of the chemical mechanisms leading to release, transformation and removal of reactive halogen species in the troposphere. Studies of consequences of the presence of reactive halogen species in the troposphere.
- Laboratory studies: Determination of gas- and aqueous-phase rate constants, Henry's law and uptake coefficients, UV/VIS spectra, and other properties of reactive halogen species.
- Field experiments and satellite studies: Measurements of inorganic (X, XO, HOX, XONO2, ..., X = Cl, Br, I) and organic (CH3Br, CHBr3, CH3I, RX, ...) reactive halogen species and their fluxes in the troposphere with in situ and remote sensing techniques.
- Measurements and model studies of the abundance of (reactive) halogen species in volcanic plumes and transformation processes and mechanisms.
- All aspects of tropical tropospheric halogens and links to (O)VOCs: their chemistry, sources and sinks, and their impact on local, regional, and global scales. Contributions reporting results from recent major field campaigns such as Climate and Halogen Reactivity Tropical Experiment (CHARLEX), Tropical Ocean tRoposphere Experiment of Reactive halogen species and OVOCs (TORERO), and Reactive Halogens in the Marine Boundary Layer (RHaMBLe) and SOLAS related activities are particularly encouraged.
