ICESat-2 sea ice ancillary data - Mean Sea Surface Height Grids

File format: NetCDF Mean Sea Surface (MSS) Height data grids used for the production of ICESat-2 sea ice data products (ATL07, ATL10, ATL20, ATL21). Blended data from CryoSat-2 and DTU13.

Description
Summary:File format: NetCDF Mean Sea Surface (MSS) Height data grids used for the production of ICESat-2 sea ice data products (ATL07, ATL10, ATL20, ATL21). Blended data from CryoSat-2 and DTU13. The MSS is derived from CryoSat-2 sea surface height retrievals during 2011-2015 (Kwok and Morison, 2015) with gaps and lower-latitude ice marginal regions filled using the DTU13 global high resolution MSS (Andersen et al., 2015), which is based on multi-mission satellite altimetry from 10 different satellites over 20 years (1993-2012). The composite data are smoothed using a 25-km Gaussian kernel after a reference ellipsoid bias correction (WGS-84 for CryoSat-2 and Topex/Poseidon for DTU13). The MSS is in a mean tide system. Heights are above WGS-84 reference ellipsoid.
