SNOWPACK and Alpine3D model simulations of the snow-sea ice system for two sea ice floes in the Weddell Sea, Antarctica, which were visited in austral winter 2013 by Research Vessel Polarstern during the AWECS campaign. MeteoIO (required for preparing the meteorological data for SNOWPACK and Alpine3D), SNOWPACK and Alpine3D is software published under a GNU LGPLv3 license by the WSL Institute for Snow and Avalanche Research SLF at https://gitlabext.wsl.ch/snow-models.

The exact model source code to reproduce/run the simulations in this repository can be accessed via DOI: https://doi.org/10.5281/zenodo.4708266. This dataset belongs to: Wever, N., Leonard, K., Maksym, T., White, S., Proksch, M., and Lenaerts, J. T. M. (2021): Spatially distributed simulations of the effect of snow on mass balance and flooding of Antarctic sea ice. J. Glaciol., 67(266), 1055-1073, doi:10.1017/jog.2021.54. Summary: ====== Simulations were run for two sea ice floes: PS81/506 and PS81/517. Meteorological driving data is provided by the MERRA-2 reanalysis. Initial conditions were chosen based on available measurements of snow and ice thickness. This dataset consists of the following files: snowpack_sim_506.zip: archive containing one-dimensional simulations using the SNOWPACK model for sea ice floe PS81/506. snowpack_sim_517.zip: archive containing one-dimensional simulations using the SNOWPACK model for sea ice floe PS81/517. a3d_sim_506.zip: archive containing spatially distributed simulations using the Alpine3D model for sea ice floe PS81/506. a3d_sim_517.zip: archive containing spatially distributed simulations using the Alpine3D model for sea ice floe PS81/517. Description of files: ============ The snowpack_sim_5XX.zip files are organized as follows: io_base.ini: configuration file embedded from other configuration files with the settings shared among both SNOWPACK as well as alpine3d simulations. ...
