Snow status (wet/dry) in Antarctica from AMSR-E and AMSR2 passive microwave radiometers 2002 – 2023

The dataset provides daily binary status (wet/dry) of the snowpack for each pixel at 12.5 km resolution in Antarctica over more than 20 years. This status is retrieved from passive microwave observations at 19 GHz and horizontal polarisation, using an algorithm developed by Torinesi et al. 2013 and Picard and Fily, 2006. The dataset merge the two timeseries from AMSR-E and AMSR2 sensors. The effective resolution of about ~25 km. There is a gap in 2011/2012 between AMSR-E and AMSR2. The ascending (afternoon) and descending (midnight) passes are provided separately.
