Dear Colleagues
we'd like to draw your attention to the 'Air-Ice Chemical Interaction' session (IACS Symposia, C10) at the IUGG 2015 General
Assembly in Prague, June 23rd-28th 2015.
Deadline for abstract submission: January 31st 2015
C10 Air-Ice Chemical Interaction

List of solicited speakers
Katarina Abrahamsson (Göteborg, Sweden), Patrick Ayotte (Sherbrooke, Canada)
The cryosphere plays an active role in Earth's biogeochemical cycles. Physical, chemical, and biological processes in snow and ice in alpine and Polar regions have been shown to cause vivid fluxes between atmosphere, cryosphere, soil, and ocean. These fluxes can contribute to the accumulation, production, or modification of certain globally transported contaminants and greenhouse gases, but also of reactive trace compounds. This symposium focuses on the chemical and biological activity in snow and ice and how these processes can impact other compartments like the atmosphere, soil, or ocean. We invite presentations on field, laboratory, and modelling studies identifying important processes and deepening our understanding of the role of the multi-phase matrix of ice and snow in such processes. The focus may range from the molecular scale identifying significant mechanisms to the local scale dealing with fluxes in isolated, well controlled experiments, but also to the regional and global scale addressed in field studies and using global transport models. Contributions regarding recent advances in model parameterization and application and the evaluation of the impact on atmospheric composition, climate, and ice core proxies useful for paleo-climate reconstruction are especially encouraged.
kind regards, Thorsten Bartels-Rausch and Hans-Werner Jacobi
