Dataset
Aiice benchmark dataset for Arctic sea ice concentration (SIC) forecasting, based on OSI-SAF satellite products (CC BY 4.0).
Coverage
- Period: October 1978 – April 2026
- Resolution: 25 km spatial, daily temporal
- Grid: 432×432 (Lambert Azimuthal Equal Area, EPSG:6931)
Source products
| Product | Source | Period |
|---|---|---|
| OSI-450-a | SMMR, SSM/I, SSMIS | 1978–2020 |
| OSI-430-a | SSMIS | 2021–Oct 2025 |
| OSI-438 | AMSR2 | Oct 2025–present |
Processing
Raw NetCDF files were downloaded from osisaf.met.no and converted to
NPY matrix format. The ice_conc variable (fully filtered SIC with
atmospheric correction) was extracted for each timestep, yielding
432×432 matrices in the 0–100 value range.
