Simulated images - Infrared channel and total precipitation
Base Time: Tue 01 Jul 2025 00 UTC T+24 Valid time: Wed 02 Jul 2025 00 UTC (T+24)
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.

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