Here are the main changes compared to MET-AICE v1: - MET-AICE v1 file names are : "AICE_forecasts_YYYYMMDDT000000Z.nc", while MET-AICE v2 file names are: "METAICE_v2_YYYYMMDDT120000Z.nc" - MET-AICE v1 provides only sea ice concentration forecasts at 5 km resolution with the variable "SIC" ranging from 0 to 100 %. MET-AICE v2 provides sea ice concentration (variable "ice_conc" ranging from 0 to 1) and drift (variables "dx" and "dy" in meters per day) forecasts at 2.5 km resolution. - MET-AICE v2 has a slightly larger geographical domain than MET-AICE v1 towards the Russian coast. - MET-AICE v1 was trained only on passive microwave observations of sea ice concentration, while MET-AICE v2 was trained on a combination of passive microwave and SAR observations. - MET-AICE v1 is currently produced around 09:30 UTC, while MET-AICE v2 is produced just after 05:00 UTC. - MET-AICE v1 does not provide the initial conditions for the sea ice concentration, while the initial sea ice concentration field (observations) is provided in MET-AICE v2.
