ECMWF has started to use newly available aircraft observations of humidity, temperature and wind to help initialise its forecasts.
We use advanced computer modelling to generate operational weather forecasts for our Member States, focusing on the medium range (to two weeks ahead), with monthly and seasonal outlooks.
Early warning of storms, heatwaves, floods and droughts.
We work with others to monitor and forecast atmospheric composition with a focus on air quality applications.
We reanalyse past atmospheric, oceanic and land-surface observations to support climate science.
We have been using supercomputers since 1977. Member States have access to 25% of our supercomputer resources.
