Using the power of data assimilation to model the COVID-19 pandemic
Given that data assimilation is such a central aspect of ECMWF’s work, Geir Evensen was invited to present a seminar and a blog covering his work on its use in modelling aspects of the COVID-19 pandemic.
Accelerating weather forecasting models using reduced-precision arithmetic
Sam Hatfield is looking at ways of reducing the computational cost of producing weather forecasts by using lower precision in the calculations. He will present his findings at ECMWF’s Annual Seminar, taking place in virtual format from 14 to 18 September.
ECMWF-led CO2 monitoring project on track for 2023 prototype
A European project to build a monitoring and verification support capability for global emissions of carbon dioxide (CO2) related to human activities is on track to deliver a prototype system by 2023, ECMWF’s project coordinator says.
Fact sheet: Earth system data assimilation
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.
Forecast charts and data
We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.
Highlighted tweet
Full documentation is now available for Cycle 47r1 of ECMWF’s Integrated Forecasting System (IFS), which became operational in July this year. IFS documentation #IFS47r1
Datasets
Forecasts, analyses, climate re-analyses, reforecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.
Accessing forecasts
Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.
Workshops and education
Education is a key element of our work at ECMWF, enabling our partners to get the most from ECMWF's services and develop an advanced understanding of forecasting.
ECMWF workshops are open to the worldwide meteorological community, though some training is restricted to member states.
Serving meteorology
International collaboration is fundamental to the work of ECMWF, working with the EU and the meteorological community at large, including the World Meteorological Organization, space agencies, and scientists around the world.
