A full description of the data processing and uncertainties is given by (Paper in submission). We use the semi-analytical retracker described fully by (Wingham, et al. 2018).
The data comes in two formats. First is the complete satellite track records, compressed into files containing the Arctic (arco) and Antarctic (anto). These consists of 1Hz data records from above 60N (arco) or below 50S (anto). The time covered is 2011-01-01 to 2022-02-28. Each satellite track is a netCDF file in this format.
The second netcdf data format is a daily gridded product. The satellite track data has been collected onto 100km resolution Polar Stereographic grids on a daily time resolution. The data is filtered to only accept records with an acceptable fit error, and we contain a mask created by analysing NSIDC daily ice concentration data.
