Quantifying the Effect of Snow-Ice Formation on Snow Depth and Density over Arctic Sea Ice
This study quantified the effect of snow-ice formation on SnowModel-LG snow depth and density products. We coupled SnowModel-LG, a modeling system adapted for snow depth and density reconstruction over sea ice, with HIGHTSI, a 1-D sea ice thermodynamic model. Pan-Arctic model simulations were perfor...

Our simulations suggest that when snow-on-sea-ice models account for snow-ice formation, snow depth can be remarkably reduced. Sea ice thickness retrievals from CryoSat-2 were guided by both snow products. Averaged across the CryoSat-2 era (2011-2022), domain average sea ice thickness retrievals decreased by 10% when snow-ice was accounted for.
