An issue has been identified with CryoSat-2 near-realtime (NRT) data for algorithm baseline-D: The NRT Level-1 data to the CryoSat-2 sea ice product is missing several orbits, mostly in the Russian Arctic. The offline reprocessed data, which trails the NRT data by one month is not affected by this issue. ESA is aware of the problem and developing a fix that will be implemented at a later stage.
NRT data is available with a delay (timeliness) of 2 days, offline-reprocessed with a delay of 33 days. All users should be aware that any of data products or analysis based on CryoSat-2 NRT sea ice data (tag `nrt` in filename) are currently degraded and should use the reprocessed data stream (tag `rep` in filename) instead.
Data coverage of the week between December 23 and 29, 2019 for near-real time data with a timeliness of 2 days (left) and offline reprocessed data with a timeliness of 33 days (right). Data coverage of the offline reprocessed data is nominal, while several orbits are missing in the near-realtime data.
