Daily snow depth on Arctic sea ice during the winter season from AMSR-E&2 data (2002 – 2024)

This dataset contains a daily snow depth on sea ice for the winter months (October - April) in the Arctic Ocean. All variables are gridded on a NSIDC Sea Ice Polar Stereographic North (EPSG:3413) at a spatial resolution of 25 km. The snow depth is derived from the newly developed algorithm proposed by He et al. (2024), which considers the influences of snow density on the relationship between gradient ratio of 6.9 and 18.7 GHz vertically polarized TBs [i.e., GRV(19/7)].
