Snow thickness measurements over relatively smooth Arctic first-year sea ice, obtained near Cambridge Bay in the Canadian Arctic (2014, 2016 and 2017) and near Elson Lagoon in the Alaskan Arctic (2003 and 2006), are analyzed to quantify physical leng

Owing to differing and complex snow geophysical properties, radar waves of different wavelengths undergo variable penetration through snow-covered sea ice. However, the mechanisms influencing radar altimeter backscatter from snow-covered sea ice, esp

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 can cause the Ku-band main radar scattering horizon to appear ab

Publikováno v: 2021 IEEE 19th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM).

We propose a modular framework for coupling sea ice thermodynamic models with microwave backscatter models for comparison to observations, with the objective of accurate accounting for snow and sea ice and associated dynamics over vast and remote are
