Sea Ice Concentration Monitoring
Source: L2 GDR-A (all acquisition modes) · Variable: sea_ice_concentration_01
Sea ice concentration (sea ice area fraction) at 1 Hz. Baseline-E: derived from NSIDC SSM/I data. Baseline-F: derived from NSIDC-0081 (before July 2025) or OSI-408-a data. Unused (fill value) in LRM mode.
