Data

The SAGE will produce the following datasets:

• Sea-ice age CDR: Daily resolution, global coverage (Arctic + Antarctic), ~25 km grid, spanning from 1978 to near present.
• Sea-ice type product: Improved classification of FYI, MYI, and transitional types (e.g. young ice, pancake ice).
• Sea-ice drift CDR: Historical extension of existing drift records (prior to 1991), resulting in a full-length CDR, global coverage, and ~75 km grid.

Data will be delivered in CF-compliant netCDF format, include full uncertainty quantification, and be accompanied by open documentation and software. These data will be accessible via the ESA CCI open Data Portal.
