The potential of deriving snow depth estimates using differences in freeboard heights from
CryoSat-2 (CS-2) and ICESat-2 (IS-2) is examined. In our analysis, we use lidar freeboard …

We present a first examination of Arctic sea ice snow depth estimates from differencing
satellite lidar (ICESat‐2) and radar (CryoSat‐2) freeboards. These estimates cover the …

Snow depth on sea ice remains one of the largest uncertainties in sea ice thickness
retrievals from satellite altimetry. Here we outline an approach for deriving snow depth that …

In this paper we develop a CryoSat-2 algorithm to retrieve the surface elevation of the air–
snow interface over Antarctic sea ice. This algorithm utilizes a two-layer physical model that …

Although snow depth on sea ice is a key parameter for sea ice thickness (SIT) retrieval, there
currently does not exist reliable estimations. In the Arctic, nearly all SIT products use a snow …

We examine the variability of sea ice freeboard, snow depth, and ice thickness in three years
(2011, 2014, and 2016) of repeat surveys of an IceBridge (OIB) transect across the Weddell …

We present a first assessment of airborne laser and radar altimeter data over snow-covered
sea ice, gathered during the National Aeronautics and Space Administration Operation …

Abstract National Aeronautics and Space Administration's (NASA's) Ice, Cloud, and land
Elevation Satellite‐2 (ICESat‐2) mission was launched in September 2018 with the primary …

We present freeboard measurements from airborne laser scanner (ALS), the Airborne
Synthetic Aperture and Interferometric Radar Altimeter System (ASIRAS), and CryoSat‐2 …

Abstract Knowledge of contemporaneous snow depth on Arctic sea ice is important both to
constrain the regional climatology and to improve the accuracy of satellite altimeter …
