Dear colleagues,
We would like to draw your attention to our symposium at IUGG Berlin 2023:
JC05: Atmosphere-Ocean-Sea Ice Interactions: Physical and Chemical Processes
https://www.iugg2023berlin.org/922-2/#IACS
Please note that we welcome submissions on atmosphere-ocean-sea ice interactions
more oriented to physical and chemical processes on regional scales.
The abstract submission deadline: 14 February 2023
Please share this mail with the interested colleagues.
We hope to see you at IUGG Berlin 2023.
Symposium description:
The rapid change of polar climate over the past several decades has significantly
affected the atmosphere-ocean-sea ice (AOI) interface and thereby interactions
such as the exchanges of energy and chemical compounds through physical and
chemical processes. These processes are linked together via chemical compound and
particle exchanges at air-snow interfaces, snow processes, polynya formation,
sea-ice production and deep-water formation. AOI interactions can be triggered also
by short-term synoptic and mesoscale weather phenomena such as cold air outbreaks,
katabatic winds, and polar lows. Thus, changes in polar weather and meteorology may
influence the natural processes involved in polar atmospheric chemistry.
However, the representation of these physical and chemical processes and interactions
at different spatial and temporal scales remains a major challenge for current weather
and climate models. This symposium aims to brings together researchers working in
the areas of atmospheric chemistry (Part I) and physics (Part II) to demonstrate
their latest findings, highlight gaps in our understanding of the physical and chemical
aspects of polar climate and the polar surface boundary layer, and inspire further
investigation and collaboration.
Part I focuses on but is not limited to: lower tropospheric oxidizing capacity; ozone;
reactive halogens and nitrogen; mercury; snow chemistry on sea ice, tundra and ice
sheets; sea salt aerosol from blowing snow; and particulate chemistry.
Part II focuses on but is not limited to: atmospheric and oceanic boundary layers,
sea ice and snow-cover processes as well as global change related to the marine Arctic
and Antarctic. Further focus is on snow cover modelling, ablation and accumulation
on sea ice; and processes or parameterizations of physical and chemical exchange, and
transport, including the influence of sub-mesoscale ocean dynamics, where observational
challenges can be addressed.
Contributions dealing with theoretical and observational studies, remote sensing, or
numerical modelling are welcome.
Best regards,
(On behalf of the conveners of this symposium)
