Depth and physical properties of snow
dominate many processes and properties of Arctic and Antarctic sea ice.
They are among the least known and most difficult to observe climate
variables, mainly due to their high spatial and temporal variability and
complex vertical structure. Active and passive microwave data, as well
as laser and radar altimeter satellite observations, have recently been
applied to retrieve snow depth over sea ice, but their accuracy and
sensitivity needs to be better understood. Snow studies using
atmospheric reanalysis products are hampered by large uncertainties and
biases. Numerical simulations of snow processes, accumulation, and
ablation from 1D micro scales to global circulation models reveal major
challenges with strong impacts on atmosphere-ice-ocean interaction.
In-situ, autonomous, and airborne observations of snow on sea ice are
advancing and are expected to become more comprehensive. We welcome
abstracts from these wide fields of snow on sea ice research.
