- 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.

These versions are available through the module tag 'may18' on the system at ECMWF, e.g. eccodes/may18, and will become the default ones on 22 May. |
ecCodes
ecCodes version 2.7.3 provides full support for the new model output parameters introduced in IFS Cycle 45r1.
...
| Note |
|---|
GRIB API is no longer loaded in the default user environment on the ECMWF systems. We will discontinue support for GRIB API at the end of 2018 and recommend to use ecCodes. |
EMOSLIB
The version of EMOSLIB used to interpolate IFS Cycle 43r3 data is suitable to handle 45r1 data.
| Note |
|---|
EMOSLIB is no longer loaded in the default user environment on the ECMWF systems. |
Magics/Metview
Magics version 3.0.3 and Metview version 5.0.2 provide full support for the new model output parameters introduced in IFS Cycle 45r1.

IFS Cycle 45r1 test data from the release candidate testing stage are available through the test dissemination system. Users of ECMWF dissemination products can trigger transmission of test products by logging in to the test ECPDS system at https://ecpds-xmonitor.ecmwf.int/ (or https://msaccess.ecmwf.int:7443) in the usual manner. In order to receive the test products, users have to have their firewall open to the relevant ECPDS Data Movers:

ENS meteograms based on IFS cycle 45r1 test data are available as of 16 May 2018 and can be viewed by selecting the "IFS cycle 45r1' model run in the ENS meteograms interface. Access to remaining web charts is now also available in the Charts Catalogue. Only the 'clickable' charts are available for the IFS cycle 45r1, by selecting the "IFS cycle 45R1" from the Model run tab above the chart.
...
Member State users of the "Simple time-critical jobs" framework can test that their scripts will work with the IFS Cycle 45r1 test data by using the limited ECaccess 'events' set up for this purpose:
