title03-07-2020 CMA reforecast type change

Please be informed that there  is an ongoing fix of the type of CMA reforecasts for the period 2019-11-11...2020-06-22. Until 2020-06-25 CMA reforecasts were wrongly encoded as of the fixed type. The correct reforecast type is "on-the-fly".  This is only a technical fix of GRIB 2 encoding but still users can be affected when reading the data as the encoding changes after 2020-06-25 at the moment. To complete fixing the whole affected period might  take couple of weeks.

Further details can be found in Issues with data.

title30-06-2020 ECMWF forecast system change

Update of ECMWF forecast system. A new version of ECMWF model (IFS cycle 47r1) was introduced at ECMWF. 

This cycle includes changes in the treatment of observations and improvements in the data assimilation and to the model. Quintic vertical interpolation in the semi-Lagrangian advection scheme has been introduced as well as the inclusion of a better surface albedo climatology making use of more data from the MODIS instrument.

New Metrics of Tropical Cyclone (TC) “size” will supplement the existing forecasts of TC track and intensity.

The processing of the IFS reforecast (run in advance) has been suspended for the July's runs so that they would be computed from tomorrow by the new model version already.

Full details can be found in Implementation of IFS Cycle 47r1 page.
