The AMSR-2 snow depth on Arctic sea ice product contains daily gridded snow depth data for the period from 2012 to 2018 (see also: AMSR-E snow depth on Arctic sea ice product (2002 to 2011), doi:10.1594/PANGAEA.902748). The product is based on an empirical algorithm using passive microwave satellite observations from the AMSR-2 (Advanced Microwave Scanning Radiometer 2) sensors on the JAXA satellite GCOM-W1, gridded on a polar stereographic grid (EPSG code 3411, Arctic) with 25 km grid resolution. Over seasonal ice, the snow depth is available from November to April. Over Arctic multiyea ice (ice that has survived at least one summer melt) the snow depth is available in March and April. Details about the algorithm are described in Rostosky et al. (2018). More details about the data product can be found in the product manual (https://seaice.uni-bremen.de/data/amsr2/SnowDepth/)
