SMOS level 3 product version v3.3 replaces v3.2
Oct 18, 2021
Access to recent CryoSat-2 science data via ftp has resumed (ESA announcement). Most recent CryoSat-2/SMOS reprocessed data is still impacted by data gap and will be reprocessed shortly.
Problems with AWI HPC systems have been solved and missing CryoSat-2/SMOS L4 data have been reprocessed.
The processing of Level 4 merged CryoSat-2/SMOS sea ice thickness data is currently interrupted due to a problem with the AWI HPC system. The processing of Level 3 SMOS sea ice thickness data remains unaffected.
The CryoSat-2 near real-time data service by ESA has resumed. The production of near real-time merged CryoSat-2/SMOS sea ice thickness data continues with a short period of data degradation due to the resulting gap of CryoSat-2 data between Dec 16 and Dec 20, 2021.
The accuracy of the near real-time merged CryoSat-2/SMOS sea ice thickness data is currently degraded due to an outage in the ESA CryoSat-2 NRT service. The production of CryoSat-2/SMOS sea ice thickness data NRT data may be suspended in the next days depending on when CryoSat-2 NRT data will be available again. The production of SMOS sea ice thickness data remains unaffected.
The production of CryoSat-2/SMOS sea ice thickness data is temporarily halted, while the server and software system is evaluated for potential weaknesses following the log4j exploit.
The algorithm of the gridded CryoSat-2/SMOS sea ice thickness data (Level-4) has been updated. The previous version v203 is now replaced by v204.
A full documation of CryoSat-2/SMOS level 4 product version v204 can be found in the CryoSat-SMOS Merged Sea Ice Thickness section.
The algorithm of the gridded SMOS sea ice thickness data (Level-3) has been updated. The previous version v3.2 is now replaced by v3.3. SMOS L3 is distributed directly and input to the CryoSat-2/SMOS L4 sea ice thickness data set.
A full documation of SMOS level 3 product version v3.3 can be found in the SMOS Sea Ice Thickness section.
