Seasonal snow cover is the largest single component of the cryosphere in areal extent,
covering an average of 46 million square km of Earth's surface (31% of the land area) each …

Abstract The National Aeronautics and Space Administration (NASA)'s Operation IceBridge
(OIB) was a 13‐year (2009–2021) airborne mission to survey land and sea ice across the …

Snow on sea ice influences the Arctic energy and heat budgets and is therefore important for
Arctic climate studies. Methods to derive snow depth based on satellite‐borne microwave …

The snow depth or snow water equivalent affects water, carbon, and energy cycles as well
as surface–atmosphere interactions. Therefore, the global monitoring of spatiotemporal …

Supraglacial liquid water at the margins of ice sheets has an important impact on the surface
energy balance and can also influence the ice flow when supraglacial lakes drain to the …

Knowledge of sea-ice thickness and volume depends on freeboard observations from
satellite altimeters and in turn on information of snow mass and sea-ice density required for …

We present an ultrawideband (UWB) frequency-modulated (FM) microwave radar instrument
capable of preserving cm-scale vertical resolution from a very long range (verified up to~ 6 …

This letter presents a novel approach to build a compact lightweight unmanned aerial
vehicle (UAV) radar for remote sensing applications. The proposed radar exploits the recent …

We developed and deployed a high sensitivity and low transmit power airborne ultra wide
band (UWB) frequency-modulated continuous-wave (FMCW) radar for snow depth …

During the concluding phase of the NASA Operation IceBridge (OIB), we successfully
completed two airborne measurement campaigns (in 2018 and 2021, respectively) using a …
