Global Sea Ice Concentration interim climate data record, release 2
| IDENTIFICATION |
| Description | This product is an operational extension of the Sea Ice Concentration Climate Data Record OSI-450, with a latency of 16 days, starting in 2016. OSI-430-b uses passive microwave data (PMW) from the SSMIS sensors, and the same algorithms as OSI-450. The product includes error-bars for each grid cell (uncertainties). |
