    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.

  • 7 April 2020

    As the situation around COVID-19 continues to evolve, ECMWF staff, whether in Italy or in the United Kingdom, are now working remotely. The operation and delivery of our mission-critical activities are not affected. Staff will continue to be available via email. For updates on our events, please check the relevant pages on this website.

    The quality of weather forecasts crucially depends on our ability to accurately estimate the current state of the Earth system. This Q&A explains how Earth system data assimilation enables us to make such estimates.

  • 6 March 2020

    To celebrate International Women’s Day 2020, ECMWF asked a selection of experts and leaders in the world of meteorology to tell us their story.

    The Copernicus Climate Change Service (C3S) activity to coordinate data rescue is an exciting and major step forward in improving the historical datasets that are so vital for assessing and managing the risks from climate change.

  • 18 March 2019

    A WMO workshop in February 2019, in which ECMWF participated, examined the requirements for ocean observations, which make a critical contribution to weather forecasts and warning systems.

  • 2 January 2019

    ECMWF will be at the American Meteorological Society (AMS) Annual Meeting in Phoenix, Arizona from 6 to 10 January. Find out when our staff are presenting and when they will be available at our booth.

  • 16 November 2018

    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.

  • 1 October 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.

    Back issues of the ECMWF Newsletter previously only published in paper form are now available in our eLibrary, along with all Newsletter feature articles published since spring 2005.

  • 14 May 2018

    A new edition of ECMWF’s user guide is now available online. The ECMWF Forecast User Guide helps forecasters and other meteorologists to make the best use of the forecast products from ECMWF.

  • 24 April 2018

    ECMWF and Ecuador’s national hydro-meteorological service, the Instituto Nacional de Meteorología e Hidrología (INAMHI), have signed a collaborative agreement for data exchange and verification of new post-processed rainfall products (“ecPoint-Rainfall”), with one long-term goal being flood impact mitigation.

  • 3 April 2018

    Since its creation, the Centre has owed its leading position to a combination of collaborative principles, top-level scientists and powerful HPC capacities. The opportunity has now arisen for a new Director of Computing to lead ECMWF’s computing efforts.

  • 6 February 2018

    ECMWF is providing support for a field campaign over the eastern Pacific called ‘Atmospheric River Reconnaissance’. The campaign is led by Scripps Institution of Oceanography’s Center for Western Weather and Water Extremes and will run until late February 2018.

  • 29 January 2018

    ECMWF’s Graduate Training Programme is an important aspect of our strong scientific cooperation with Member and Co-operating States. Here, three current Graduate Trainees from the national meteorological services of Croatia, Hungary and Serbia talk about their experiences at ECMWF.

  • 24 November 2017

    Weather and climate 'dwarfs' designed and implemented in this ECMWF-led project are a major step towards re-structuring existing computational kernels for weather forecasting. They will serve as building blocks for exascale-ready solutions.
