News
- We have been informed about an issue with two wave output parameters, "mean wave period based on first moment for wind waves" (shortName=p1ww, paramId=140223) and "mean wave period based on second moment for wind waves" (shortName=p2ww, paramId=140224). The data values are wrong. We are working on a fix which will be implemented soon.
Please note that in isolated grid points, the 2m temperature (shortName=2t, paramId=167) is lower than those of surrounding grid points. This is linked to the 2m temperature computation in cases when the surface is wet due to rain or dew, or if there is a lake in the gridbox. Other model fields, including the skin temperature and the lowest model fields are unaffected. We are currently testing a correction and will implement it soon.
- We are happy to inform our users that the implementation of the new IFS cycle happened successfully, starting with the 06 UTC run of the Boundary Conditions Optional Programme on . See News release.
- We have re-opened the dissemination requirements interface on at 08:00 UTC.
- Users can request the new model output parameters listed below from the dissemination system.
- We would like to thank all our users for their testing the new IFS Cycle 46r1 data and products during the release candidate phase.
- Please do not hesitate to contact our Service Desk if you experience any problem after the implementation of the new IFS Cycle 46r1.

The extended-range impact of model changes associated with 46r1 is neutral, except for a small degradation of 2-metre temperature and precipitation skill scores in the tropics. However, the use of ERA5 instead of ERA-Interim as initial condition gives significant improvements iwave_p2ww.gribmprovements in weeks 1-2 in the extratropics, and up to week 4 in the tropics.
