The ARICE funded project DEARice (DEvelopment of snow/ice/ecosystem models using winter-to-summer ARctic observations of coupled snow, ice, and ecosystem processes) took part during the MOSAiC expedition. The aim was to collect unique data on snow and sea ice over a full year to improve our process-level understanding of processes that can eventually feed into the improvement of models. The COVID-19 pandemic caused substantial changes in the leg planning after April 2020, however, the resulting data set is very close to the optimal outcome. Serendipitous luck made it possible to sample snow for all four seasons, including the mysterious summer “snow”, called surface scattering layer.

The results from this project encompass all relevant spatial scales, from microstructural processes in the snowpack and at the ice surface, to ridge scale observations of snow distribution and ice thickness, to snow-atmosphere interactions and albedo processes of the sea ice cover. Understanding how these different scales interact will improve our understanding of the vulnerability of the Arctic sea ice system, and decrease uncertainties in climate projections.

Speakers are Martin Schneebeli (WSL Institute for Snow and Avalanche Research SLF), Ruzica Dadic (Victoria University of Wellington), Mats Granskog (Norwegian Polar Institute), Polona Itkin (UiT - The Arctic University of Norway), Jari Haapala (Finnish Meteorological Institute), Roberta Pirazzini (Finnish Meteorological Institute) and Henna-Reetta Hannula (Finnish Meteorological Institute)
