ECMWF at the EGU General Assembly 2025 25 April 2025 We are participating in the European Geosciences Union (EGU) General Assembly from 27 April to 2 May. Find out which sessions our staff are involved in as speakers, poster presenters and conveners.
Fact sheet: ECMWF and the EU’s Destination Earth initiative 18 December 2024 Destination Earth (DestinE) is an ambitious initiative of the European Union to develop a highly accurate digital twin of the Earth system by 2030. ECMWF is one of three entrusted entities to implement it by delivering digital twins and the Digital Twin Engine.
Storm Boris and European flooding September 2024 23 October 2024 In this article we look at the exceptional rainfall and flooding associated with storm Boris and discuss how well the forecasts from ECMWF and the European Flood Awareness System anticipated the event.
Monitoring the ozone layer – the role of the Copernicus Atmosphere Monitoring Service 16 September 2024 On World Ozone Day, we look at the crucial role played by the Copernicus Atmosphere Monitoring Service in tracking the Antarctic ozone hole and providing vital data to help assess its path to recovery.
Machine learning and physics in weather forecasting: a discussion between Alan Thorpe and Florian Pappenberger 17 June 2024 Alan Thorpe, former Director-General at ECMWF, and Florian Pappenberger, our current Deputy Director-General and Director of Forecasts and Services, discuss the enormous opportunities and challenging issues for machine learning and weather forecasting.
Migration to GRIB2 data format: implications for users 10 April 2024 For some time, ECMWF has been working towards using GRIB2 as the format for data output, bringing numerous benefits. Here we explore the advantages, the impact on users, and how to stay up-to-date with the migration progress.
Plans for high-resolution forecast (HRES) and ensemble forecast (ENS) control run 5 March 2024 Since ECMWF medium-range ensemble (ENS) and high-resolution (HRES) forecasts now have the same horizontal resolution, we plan to stop using the term ‘HRES’. Find out about the time frame for this change.
ECMWF at the AMS Annual Meeting 2024 22 January 2024 At the American Meteorological Society (AMS) Annual Meeting 2024, ECMWF will present developments in areas including forecasting system improvements, data assimilation, our new AIFS data-driven model, data storage and extraction, open data, and global fire activity and emissions.
ECMWF at the AGU Fall Meeting 2023 8 December 2023 At the American Geophysical Union Fall Meeting, ECMWF will present developments in modelling for numerical weather prediction and fire risk, the Copernicus Climate and Atmosphere Data Store, data from the Year of Polar Prediction (YOPP), and work towards the European Green Deal Data Space.
ECMWF at COP28 28 November 2023 At COP28, ECMWF will discuss how, in collaboration with Member States and international partners, we can find new routes to better weather forecasts and early warning systems. We will also highlight how quality-assured data from the EU Copernicus services we run support national and global policy-making and climate action.
Fact sheet: ECMWF and the EU’s Copernicus programme 11 September 2023 ECMWF contributes to the EU's Copernicus Earth observation programme by running the Copernicus Atmosphere Monitoring Service and the Copernicus Climate Change Service, and by contributing to the Copernicus Emergency Management Service.
ECMWF at the EMS Annual Meeting 2023 1 September 2023 An overview of ECMWF participation at the Annual Meeting of the European Meteorological Society (3–8 September 2023). Our scientists will discuss topics including probabilistic forecasting, weather and climate modelling, open data, machine learning, and the EU Destination Earth initiative.
Fact sheet: Reanalysis 23 August 2023 Reanalysis data provide the most complete picture currently possible of past weather and climate. This fact sheet explains what reanalysis is and what it is used for.
July 2023 set to be hottest month on record – Copernicus and WMO 27 July 2023 According to ERA5 data from the EU-funded Copernicus Climate Change Service implemented by ECMWF, the first three weeks of July have been the warmest three-week period on record and the month is on track to be the hottest on record, a press release issued by C3S and the World Meteorological Organization says.
ECMWF high-performance computing facility boosts forecasts and research 24 July 2023 In October 2022, ECMWF started to use its Atos high-performance computing facility. It has allowed the Centre to increase the resolution of its medium-range ensemble forecasts and to provide extended-range forecasts with more ensemble members.
ECMWF science on show at EGU 2023 21 April 2023 Many of our scientists are presenting at this year’s General Assembly of the European Geosciences Union (EGU) running from 23 to 28 April. Find out here which sessions they are involved in.
ECMWF at the AMS Annual Meeting 2023 9 January 2023 Topics to be presented by ECMWF at the American Meteorological Society Annual Meeting (8 to 12 January 2023) range from forecasting system improvements and open data to user outreach and engagement, digital twins and the work of the EU Copernicus services implemented by ECMWF.
Fact sheet: Extended- and long-range predictions 5 December 2022 ECMWF issues extended-range weather predictions up to 46 days ahead. They are ensemble forecasts, and they show predicted week-to-week changes in the weather. Long-range predictions are ensemble forecasts, too, and they are mainly issued up to seven months ahead.
30 years of ensemble forecasting at ECMWF 24 November 2022 2022 marks 30 years since ensemble forecasting became operational at ECMWF. Here we look back over the last three decades and forward to future developments.
