Search ECMWF datasets

Due to the move of our Meteorological Archival and Retrieval System (MARS) to the new Data Centre in Bologna there will be no or degraded access to the archive datasets listed below at times between June and October 2022.
Please visit our dedicated data centre migration pages for more information.
Thank you for your patience and support during this important move, which will allow exciting scientific developments and overall better service.

  1. Ensemble (ENS) of forecasts providing an estimate of the reliability of a single forecast. ENS offers  "High Frequency products"  until step 144: 4 daily runs: 00, 06, 12 and 18 UTC hourly until step 90 3-hourly from 93 to 144 Post-processed Pro ...

  2. Twice a week, the ENS model is extended up to 46 days. ENS extended products comprise ensembles of individual forecasts and post-processed products of average conditions (e.g. weekly averages) and the associated uncertainty. The purchase of the "Basi ...

  3. Single prediction that uses observations prior information about the Earth-system ECMWF's highest-resolution model HRES Direct model output Products offers "High Frequency products"   4 forecast runs per day (00/06/12/18) (see dissemination ...

  4. Multi-model seasonal forecast (STREAM=MMSF) The original data in daily and subdaily frequencies for all the individual members from each one of the forecasting systems. Both forecast and hindcasts are included here. Multi-model seasonal forecast atmospher ...

  5. initialised at equivalent intervals during the period 1993-2016. The datasets present subdaily (6h) and daily ... to use non-European contributions to these datasets. These additional terms and conditions are described ...

  6. Climate forcing, also known as Radiative Forcing, determines the change in globally-averaged temperature change due to the natural or human-induced changes to the energy budget. The climate forcing estimates of CAMS quantify the climate forcings exerted b ...

  7.  CAMS Global  atmospheric composition forecast  production system is used to produce the daily forecasts of pollutants, aerosols and greenhouse gases across the globe. Satellite observations of atmospheric composition are merged with a detailed computer s ...

  8. The CAMS reanalysis is the latest global reanalysis data set of atmospheric composition (AC) produced by the Copernicus Atmosphere Monitoring Service, consisting of 3-dimensional time-consistent AC fields, including aerosols, chemical species and greenhou ...

  9. Copernicus Atmosphere Monitoring Service produces global atmospheric inversion for methane, carbon dioxide and nitrous oxide using the atmospheric inversion framework PyVAR. The framework uses a process called data assimilation, or flux inversion, where g ...
