  • The parameter CI (sea-ice fraction, paramId 31) has wrongly been encoded using 24 bits per value, instead of 16, for the Analyses in the Cycle 45r1 test data: This issue only affects the data archived in MARS, not the data available through the dissemination. The problem has been fixed as of the Analysis of 18UTC on 31 May 2018.
  • We have identified an issue with the Cycle 45r1 Simulated Satellite imagery data. We are investigating this problem. These products may not be fixed in time for the implementation on 5 June. In this case, we will update the new Cycle 45r1 later to address this issue.

  • May we remind our users to download the  Cycle 45r1 expver 0072 re-forecasts from ECPDS, e.g for 4 June and 7 June, they need for their operational activities after the implementation of the new cycle.
  • The implementation of the new cycle is confirmed for Tuesday 5 June 2018. The first operational run using the new cycle will be the 06 UTC analysis and forecast in the Boundary Conditions Optional Programme on 5 June followed by the 12 UTC main assimilation and forecast. The monthly forecast extension to the ensemble will be run with the new IFS cycle for the first time the following Thursday 7 June 2018.

  • Please note that the bathymetry (water depth) has changed with the IFS Cycle 45r1 . See below for more information. Apologies for this late notification.
  • We have been informed about a change of values for the ecCodes key named timeRangeIndicator in the cycle 45r1 GRIB1 data at step 0 since the run of 18 April 2018 at 00Z. The cause of this change has been identified and is fixed for the 06Z BC run of 21 May 2018 onwards.
  • The CAMS (Copernicus Atmosphere Monitoring Service) real-time data assimilation and forecasting system will be upgraded to IFS cycle 45r1 on 26 June 2018. More information can be found in the Implementation of IFS cycle 45R1_CAMS.
