Source products

Product	Source	Period
OSI-450-a	SMMR, SSM/I, SSMIS	1978–2020
OSI-430-a	SSMIS	2021–Jul 2025

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.

The full download and processing pipeline is available in the Aiice toolbox.
