Global Sea Ice Concentration (AMSR-2)

IDENTIFICATION
DescriptionThe High Latitude Level 3 Global AMSR Sea Ice Concentration consists of these major fields: - Sea ice concentration. Indicates the fraction of a given ocean grid point covered by ice. - Uncertainties. The algorithm uncertainty, the smearing uncertainty and the resulting total uncertainty of each sea ice concentration grid cell. - Confidence level. Based on the daily standard deviation within each grid cell, provided as a guide. This product is complementary to the SSMIS global sea ice concentration product (OSI-401-b)
