Winter 2023/24 Newsletter published 19 January 2024 The winter 2023/24 issue of the ECMWF Newsletter is now available. As well as news about ECMWF staff and events, it features articles about new developments and the use that can be made of ECMWF products.
European met services pool resources to intensify use of AI in weather prediction 10 January 2024 ECMWF’s Member States have approved two major initiatives to intensify the development, testing and implementation of machine learning across their weather forecasting chains.
2023 was the hottest year on record, Copernicus data show 9 January 2024 High temperatures from June onwards led to 2023 becoming the warmest year on record by a large margin, close to 1.5°C above the pre-industrial level, according to the EU's Copernicus Climate Change Service (C3S) implemented by ECMWF.
News highlights of 2023 21 December 2023 ECMWF news highlights in 2023 include a major upgrade of the forecasting system; initiatives to drive forward weather science, including developments in machine learning; and news from the EU-funded services implemented by ECMWF.
Data assimilation and climate specialist Jean-Noël Thépaut bows out 18 December 2023 Jean-Noël Thépaut, who started his career at ECMWF in the early 1990s and rose to become the Director of the two EU Copernicus services run at the Centre, is leaving us at the end of this year on reaching retirement age.
Confirmation of phase two of Destination Earth 14 December 2023 The second phase of the Destination Earth (DestinE) initiative was confirmed on 13 December 2023 by the European Union and unanimously endorsed by the Councils of the three implementing entities delivering DestinE.
Project to improve transport modelling of atmospheric composition tracers 11 December 2023 CATRINE, an EU-funded project coordinated by ECMWF, will improve the numerical aspects of the transport of atmospheric tracers, with an emphasis on long-lived greenhouse gases. It will support an operational anthropogenic greenhouse gas emissions Monitoring and Verification Support Capacity.
ECMWF supports global initiative to provide more weather observations 4 December 2023 ECMWF supports the UN’s Systematic Observations Financing Facility (SOFF) to widen the provision of weather observations in some countries, notably by agreeing to supply its forecasts to SOFF participants.
The current forecasting equations are still valid near km-scale resolution 22 November 2023 Recent investigations suggest that the equations ECMWF uses to forecast the global weather may not have to be updated to much more computationally demanding ones as long as the weather model’s horizontal grid spacing is no smaller than 2.8 km.
Looking for aspects of ECMWF’s weather model that can be improved 16 November 2023 Rebecca Emerton is part of a team that tries to improve ECMWF’s weather model by looking for the causes of errors. She is also helping the EU’s Copernicus Climate Change Service, which is implemented by ECMWF, to draw up its yearly review of the climate.
How machine learning can support data assimilation 6 November 2023 Data assimilation is the combination of the latest observations with a short-range forecast to obtain the best possible estimate of the current state of the Earth system. Machine learning can contribute to it by optimising the use of satellite observations.
Week-long high-performance computing event looks into ‘Diversifying HPC’ 25 October 2023 Over 140 people attended ECMWF’s 20th Workshop on High-Performance Computing in Meteorology in Bologna, Italy, from 9 to 13 October 2023, and nearly 170 registered online. The theme was ‘Diversifying HPC’.
Autumn 2023 Newsletter published 20 October 2023 The autumn 2023 issue of the ECMWF Newsletter is now available. As well as news about ECMWF staff and events, it features articles about new developments and the use that can be made of ECMWF products.
Destination Earth to hold second user event in November 16 October 2023 The EU’s Destination Earth initiative, implemented by ECMWF, EUMETSAT and ESA, will hold its second User eXchange meeting on 13–14 November 2023 in Bonn, Germany.
How to optimise the cost and speed of high-performance computing 9 October 2023 Laleh Pouyan tries to minimise the cost while maximising the speed of high-performance computing (HPC) used in weather forecasting. She will present a poster on her work at the ECMWF workshop on HPC in meteorology from 9 to 13 October 2023.
OpenIFS to adopt latest version of the Integrated Forecasting System 2 October 2023 OpenIFS, a supported and easily accessible version of ECMWF’s Integrated Forecasting System (IFS) provided for research and education, is to be upgraded to the latest IFS model cycle by the end of this year.
The European Weather Cloud is operational 26 September 2023 The European Weather Cloud, a distributed cloud computing infrastructure of ECMWF and EUMETSAT providing access to data and other services from the two organisations, becomes operational on 26 September 2023.
Copernicus service backs WMO's Global Greenhouse Gas Watch initiative 19 September 2023 The EU-funded Copernicus Atmosphere Monitoring Service (CAMS), implemented by ECMWF, is working to support a new Global Greenhouse Gas Watch introduced by the World Meteorological Organization.
Annual Seminar on reanalysis shows evolution towards enhanced coupling 13 September 2023 About 100 scientists and students came together from 4 to 8 September 2023 for the Annual Seminar at ECMWF in Reading, UK, to learn about the history and state of the art of Earth system reanalysis activities.
