Global Sea Ice Concentration (AMSR-2)
| IDENTIFICATION |
| Description | The 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) |
