IOCAS-SIPNet sea ice prediction for SIPN​ south 2025-2026

IOCAS-SIPNet_005_20251201-20260228_total-areaThis file contains a single row of 90 comma-separated values, representing the daily sea-ice area for the 90-day period from December 1st, 2025, to February 28th, 2026 (31 + 31 + 28 days).Units: 106 km2 (million square kilometers).IOCAS-SIPNet_005_20251201-20260228_regional-areaThis file contains 36 rows, each consisting of 90 comma-separated values, following the same time format as the total-area file. Each row corresponds to a 10° longitude bin.Row format: The 1st row covers 0°–10°, the 2nd row covers 10°–20°, ..., and the 36th row covers 350°–360°.Units: 106 km2.IOCAS-SIPNet_005_20251201-20260228_concentrationA NetCDF file containing 90 time steps, providing daily spatial fields of sea-ice concentration from December 1st, 2025, to February 28th, 2026. Variable specifications are as follows:siconc: Sea-ice concentration, defined as the fraction of the grid cell covered by sea ice (Units: %).longitude / latitude: Geolocation coordinates.sftof: Land-sea mask, expressing the percentage of the grid cell covered by ocean (Units: %).areacello: Area of the grid cell (Units: m2).
