We have just added more than 50 new products to our #OpenCharts catalogue! These forecast charts are free for anyone to access, redistribute & adapt - even for commercial applications - part of our open data Strategy for 2021-2030.
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.
Forecasts, analyses, climate reanalyses, re-forecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.
Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various licence agreement types.
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.
