Blog from September, 2020

Back in June ECMWF implemented a substantial upgrade of its Integrated Forecasting System (IFS). IFS Cycle 47r1 included changes in the forecast model and in the data assimilation system. The upgrade has had a small positive impact on forecast skill in medium-range and extended-range forecasts in the troposphere and a large positive impact on analyses and forecasts in the stratosphere. 

We are pleased to announce that the full IFS Cycle 47r1 documentation  is now available.

Following ECMWF Council decision in June 2020, we are pleased to announce the availability of Tropical Cyclone trajectories for the 06/18 UTC forecast cycles in test mode. For further details see   Tropical Cyclone tracks from the 06/18 UTC forecast cycles : Test Products

Moreover, WMO essential products (publicly available) and additional products (available to NMHS of WMO countries) from the 06/18 UTC forecast cycles are available. Please check the products description and download instructions.  

Also, four new parameters, previously available via the ACMAD data feed, will now be available as WMO additional products:
