Advancing global NWP through international collaboration

Simulated images - Infrared channel and total precipitation

Base Time: Sun 19 Sep 2021 00 UTC T+24 Valid time: Mon 20 Sep 2021 00 UTC

Simulated Forecast image products 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.

Precipitation which includes all precipitation types (rain, snow etc.) is represented using colour shades and has units of mm of rainfall equivalent.

Forecast charts and data

We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.

Cycle Upgrade 47r2

Highlighted tweet

ECMWF has implemented an upgrade of its Integrated Forecasting System, including a move from double to single precision and an increase in the vertical resolution of ensemble forecasts. #IFS47r2 #newfcsystem Find out more here: https://www.ecmwf.int/en/about/media-centre/news/2021/forecast-upgrade-i...

Datasets

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.

ECMWF lecture theatre

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