ECMWF and the Group on Earth Observations (GEO)

ECMWF is one of 127 participating organisations which, together with 105 member nations and the European Union, form the Group on Earth Observations (GEO). Here we look at GEO’s important work and how ECMWF both benefits and contributes.

ECMWF extended-range forecasts and the European heatwave of summer 2018

The heatwave of summer 2018 highlighted the skill and value of our extended-range (sub-seasonal) forecasts. Forming part of ECMWF's seamless prediction system, the extended range falls between the medium- and long-range (seasonal) timescales. Forecasts on the extended-range timescale are scientifically challenging, but skill has been increasing steadily.
