Advancing global NWP through international collaboration

Simulated images - Infrared channel

Base Time: Fri 01 Jul 2022 00 UTC T+0 Valid time: Fri 01 Jul 2022 00 UTC

Simulated Forecast Image products (SIM) are based on the sensor characteristics of the Meteosat-10 satellite. They are generated from the model forecast fields using the same radiative transfer algorithm (RTTOV) as in the ECMWF operational data assimilation. The forecast brightness temperature is used to produce pictures equivalent to the infra-red images available from geostationary satellites.

High resolution forecast Mean sea level pressure contours are overlaid to aid the interpretation.

Predicting the impact of new satellites on ECMWF’s forecasts

ECMWF’s Ensemble of Data Assimilations is providing a novel and efficient way to assess the impact of new satellite observations and to help inform the development of the Global Observing System. Sean Healy and Katrin Lonitz discuss some of the latest work.

Global numerical modelling at the heart of ECMWF’s forecasts

Our global numerical model has evolved from atmosphere only to encompass the Earth system as a whole. This Earth system approach underpins all our forecasts and it has opened up the development of  a range of environmental services.

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.

Serving meteorology

International collaboration is fundamental to the work of ECMWF, working with the EU and the meteorological community at large, including the World Meteorological Organization, space agencies, and scientists around the world.

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.

ECMWF lecture theatre

ECMWF workshops are open to the worldwide meteorological community, though some training is restricted to member states.
