The global sea ice drift climate data record version 1

The OSI SAF Sea Ice Drift (SIDR) Climate Data Record (CDR) (OSI-455) is the first release of a sea-ice drift CDR by OSI SAF. It builds on the methodologies of the near-real-time sea-ice drift product (OSI-405).

More details of these data records are provided in the Product User Manual (PUM), Algorithm Theoretical Basis Document (ATBD) and Scientific Validation Report (SVR). 

The global AMSR sea ice concentration climate data record version 3

OSI-458 is the third major version of the Global AMSR Sea Ice Concentration Climate Data Record (SIC CDR v3.0). The previous two versions have been released by the ESA CCI Sea Ice projects, while OSI SAF has now taken over the responsibility to maintain this data record.

The global sea ice concentration climate data record version 3

OSI-450-a is the third major version of the OSI SAF Global Sea Ice Concentration Climate Data Record (SIC CDR v3.0). OSI-430-a is the corresponding Interim CDR, an operational extension with a latency of 16 days.

The level-2 sea ice concentration product (OSI-410)

The level 2 sea ice concentration product is a swath based product and is complementary to the level 3 SSMIS sea ice concentration (OSI-401-b) and the level 3 AMSR-2 sea ice concentration (OSI-408) products. All the products are near-realtime, operational and freely available, as all the products in the Ocean and Sea Ice Satellite Application Facility's (OSI SAF's) product portfolio. The product utilises the AMSR-2 and SSMIS satellite microwave radiometer data.
