Copernicus projects CERISE, CAMEO and CORSO

Three research projects to improve ECMWF’s Copernicus services

January 2023 marked the start of three EU-funded research projects to further develop the EU’s Copernicus Climate Change Service and Copernicus Atmosphere Monitoring Service implemented by ECMWF: CERISE, CAMEO and CORSO.
World Meteorological Day 2023 main image

The future of weather, climate and water across generations

On World Meteorological Day, ECMWF Director of Forecasts Florian Pappenberger reflects on the WMO’s critical role and the importance of international collaboration for the future of weather, climate and water across generations.

Destination Earth demonstration products to be ready by mid-2024

ECMWF will ensure that the EU’s Destination Earth initiative has completed the first steps in developing highly accurate replicas of Earth to facilitate action on climate change and environmental extremes by mid-2024.
Rainfall change in the Arctic

New data show a wetter and warmer Arctic

Scientists from the EU’s Copernicus Climate Change Service (C3S) implemented by ECMWF have observed major changes in Arctic precipitation, air temperature and sea-ice coverage over the most recent three decades. Reanalysis enables a new focus on the Arctic climate.

How to monitor observations to ensure the best possible forecasts

Numerical weather predictions rely on observations to help establish the initial conditions of forecasts as accurately as possible. Mohamed Dahoui monitors weather observations at ECMWF to ensure they are of good quality.

The growing role of machine learning at ECMWF

Machine learning is entering many aspects of weather forecasting. At ECMWF, a team of three people is supporting these activities. They expect machine learning to continue to play a growing role in weather forecasting.
2022 surface air temperature anomaly

The year 2022 was the second warmest on record in Europe

The year 2022 was the second warmest on record in Europe, and the summer of 2022 was the hottest in Europe, data released by the European Union’s Copernicus Climate Change Service (C3S) run by ECMWF show.

25 years of 4D-Var: how machine learning can improve the use of observations

Twenty-five years ago, ECMWF introduced ‘4D-Var’ to the assimilation of observational data into its weather model. Changes worked on over the last few years include reducing the effects of model biases using machine learning techniques.
EUMETSAT's MTG-I1 satellite

New geostationary satellite to bring benefits for ECMWF’s forecasts

EUMETSAT is planning to launch a new geostationary satellite in December that provides more frequent and higher-resolution images than its predecessor and carries a new instrument to observe lightning flashes.

Copernicus Emergency Management Service releases GloFAS v4.0 hydrological reanalysis

A new, substantially upgraded hydrological reanalysis dataset of the Global Flood Awareness System from 1980 to July 2022 has been produced by the Joint Research Centre of the European Commission in collaboration with ECMWF and released as part of the Copernicus Emergency Management Service.
C3S forecast for December-January-February from November 2022

How models predict a possible outline of winter weather in Europe

ECMWF produces not just weather forecasts 15 days ahead but also forecasts for weeks and seasons ahead. The latter contribute to multi-centre predictions provided by the EU’s Copernicus Climate Change Service run by ECMWF.
