This data set uses CryoSat-2 data to produce monthly gridded sea ice thickness, freeboard, and roughness fields. The data set is archived from after the launch of CryoSat-2 in 2010 and will be updated on a daily basis during the sea ice growth season for the central Arctic region. Browse images of sea ice thickness are also available with the products. A lower level product with shot-to-shot retracked surface elevation data and associated fit parameters used during the waveform fitting process will be made available soon via NSIDC as well.
