Sea Ice Satellite-Observed Floe Length from Altimetry

Overview Each .nc file contains satellite-observed floe length (SOFL) in km, derived from CryoSat-2 or ICESat-2 Along-track SOFLs are gridded and averaged on a 5 km square Polar Stereographic grid SOFLs are averaged for the sea ice growth season only (October-April), from October 2019 to April 2023 CryoSat-2 Products The CryoSat-2 products are derived from standard (FloeLength_CPOM.nc) or fully-focused SAR (FloeLength _FFSAR.nc) processing ICESat-2 Products The ICESat-2 products are derived from ATL07 sea ice surface height data (FloeLength _ATL07_both.nc and FloeLength _ATL07_spec.nc) or ATL10 sea ice freeboard data (FloeLength _ATL10.nc The two product versions for ATL07 are; “both” where specular and dark leads are treated as lead, and “spec” where only specular leads are treated as lead
