Science Summary:
This project will help answer one of the key questions being asked by the international Arctic climate-science community: What is the role of snow-on-sea-ice in controlling heat exchanges in the Arctic climate system? This work will educate young scientists in the combined issues of field measurements, high-resolution modeling, and representing high-resolution processes in regional and global models. In addition, it will collect high quality field measurements that will advance Arctic system science for years to come. This research will synthesize three interrelated science contributions: (1) Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) field observations will identify governing physical processes, fluxes, and linkages within the Arctic climate system. (2) Realistic-resolution (meters-scale), physically based modeling tools (e.g., MicroMet, SnowModel, EnBal, SnowPack, SnowTran-3D, SnowDunes, SnowAssim, SeaIce-3D) will quantify the behavior, interactions, and sensitivities among the Arctic system components. (3) Field observations and high-resolution modeling will be integrated to define what is missing or poorly represented in Earth System Models and guide the parameterization of the associated snow-related processes and fluxes for the Community Earth System Model (CESM) and the Los Alamos Sea Ice Model (CICE).

Logistics Summary:
This project wil participate in the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) field campaign onboard the German Icebreaker RV Polarstern, drifting with the sea ice across the central Arctic during year 2019 and will study the role of snow-on-sea-ice in controlling heat fluxes in the Arctic climate system. In 2019 and early 2020 two field researchers will join the R/V Polarstern during the second leg of the MOSAiC cruise. They will collect a suite of observations measurements related to initial sea ice formation, as well as snow accumulation and snow property distribution and evolution.

CPS will provide safety/communications equipment, safety training and travel support as needed. All other logistics support will be provided by Alfred Wegener Institute (AWI) via the user day fee and/or covered by the PI direct to grant. The AWI user day fee will be covered via an agreement between the NSF and AWI.
