Abstract The European Space Agency's CryoSat‐2 satellite mission provides radar altimeter
data that are used to derive estimates of sea ice thickness and volume. These data are …

Snow plays an essential role in the Arctic as the interface between the sea ice and the
atmosphere. Optical properties, thermal conductivity and mass distribution are critical to …

Arctic rain-on-snow (ROS) deposits liquid water onto existing snowpacks. Upon refreezing,
this can form icy crusts at the surface or within the snowpack. By altering radar backscatter …

Differentiating between first-year ice (FYI) and multi-year ice (MYI) in C-band synthetic
aperture radar (SAR) imagery during spring–summer melt, when wet snow and melt ponds …

An extensive perennial firn aquifer was previously mapped in Helheim Glacier, Southeast
Greenland. However, critical constraints on aquifer thickness have been so far unobtainable …

Uncertainty in snow properties impacts the accuracy of Arctic sea ice thickness estimates
from radar altimetry. On first-year sea ice (FYI), spatiotemporal variations in snow properties …

We evaluate the effects of rapidly changing Arctic sea ice conditions on sea salt aerosols
(SSA) produced by oceanic wave‐breaking and the sublimation of wind‐lofted salty blowing …

The delivery of surface meltwater through englacial drainage systems to the bed of the
Greenland Ice Sheet modulates ice flow through basal lubrication. Recent studies in …

Compact-polarimetry (CP) synthetic aperture radar (SAR) observations are presented for
major sea ice types in each ice season. CP data for three wide-swath Radarsat …

Snow plays an important role in the Arctic climate system, modulating heat transfer in
terrestrial and marine environments and controlling feedbacks. Changes in snow depth over …
