Advancing global NWP through international collaboration

   High resolution mean sea level pressure and ensemble spread 

High resolution mean sea level pressure and ensemble spread

   Thursday 28 May, 12 UTC T+96 Valid: Monday 01 June, 12 UTC

   Ensemble forecasts explained
   One 'ensemble forecast' consists of 51 separate forecasts made by the same computer model, all activated from the same starting time. The starting conditions for each member of the ensemble are slightly different, and physical parameter values used also differ slightly. The differences between these ensemble members tend to grow as the forecasts progress, that is as the forecast lead time increases.

Towards improved forecasts in Northern Europe with a new snow model

   Jonny Day and Gabriele Arduini discuss how they are using Finnish Meteorological Institute observations at a snow-covered boreal site in Lapland to improve the ECMWF snow model and forecasts in Northern Europe.

   IFS Cycle 47r1 May 2020 webinar details

Webinars to explain how June’s IFS upgrade improves forecasts

   ECMWF upgrades its forecasting system on a regular basis, and one such upgrade is planned for 30 June 2020. Director of Forecasts Florian Pappenberger will explain how the changes improve forecasts in two webinars on 27 and 28 May 2020.

Progress towards using visible light satellite data in weather prediction

   ECMWF scientists have made progress in using visible light satellite data to estimate the concentration of small particles suspended in the atmosphere. Their work could pave the way for the fuller use of such data in numerical weather prediction.

COVID-19 (coronavirus) update 

   As the situation around COVID-19 continues to evolve, ECMWF staff, whether in Italy or in the United Kingdom, are now working remotely. The operation and delivery of our mission-critical activities are not affected. Staff will continue to be available via email. For updates on our events, please check the relevant pages on this website.

   Highlighted tweet

   More and better aircraft-based observations to improve the quality of weather forecasts are possible if all involved work together, according to experts meeting at ECMWF last month. @WMO #EUMETNET



   Forecasts, analyses, climate re-analyses, reforecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.


   Accessing forecasts

   Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.

Workshops and education

   Education is a key element of our work at ECMWF, enabling our partners to get the most from ECMWF's services and develop an advanced understanding of forecasting.
