CRYO2ICE radar/laser freeboards, snow depth on sea ice and comparison against auxiliary data during winter seasos 2020-2022 ...
We investigated the near-coincident radar and laser altimetry observations from the CryoSat-2 and ICESat-2 Resonance (CRYO2ICE) campaign, which was initiated in July 2020, for the winter seasons of 2020-2022. We extracted Arctic radar and laser freeboard (the elevation of sea ice above the local sea...

Summary: | We investigated the near-coincident radar and laser altimetry observations from the CryoSat-2 and ICESat-2 Resonance (CRYO2ICE) campaign, which was initiated in July 2020, for the winter seasons of 2020-2022. We extracted Arctic radar and laser freeboard (the elevation of sea ice above the local sea level depending on scattering horizon), and binned the ICESat-2 observations (r005, ATL10) to the CryoSat-2 observations using a search radius of 3500 m and applied inverse-distancing-weightning. From ICESat-2, both strong and weak beams from all three beam pairs were included. For CryoSat-2, we make use of the Baseline-E from the European Space Agency (ESA), and include two further products using two other retrieval methodologies (CCI+ and LARM). We further derived snow depth from the difference in penetration of the radar and laser (using the freeboards), and this high-resolution orbit-based snow depth estimates were compared with nearest-neighbouring observations from basin-scale snow depth composites using ... |
