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 February and June 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. A vast amount of data is archived daily containing IFS (Integrated Forecast System) experiments produced by ECMWF's Research Department or by Member States' users at ECMWF. Basically, an experiment can address any area of meteorology and it is a ...

  2. as well. A preliminary ERA5 back extension dataset  from 1950 to 1978 is now available. ERA5 combines  vast ...

  3. Atmospheric model Analysis runs for the four main synoptic hours 00, 06, 12 and 18 UTC; forecast runs out to 10 days based on the 00/12 UTC analysis forecast. Data is produced at the surface, on model levels, pressure levels, isentropic levels and levels ...

  4. Some Member States also archive output other than from IFS into MARS. One example of such activity is the COSMO-LEPS forecast suite, running daily at ECMWF. Member State Projects ECMWF Member States Access the MARS Catalogue version 🔒 ECMWF ...

  5. It is the Limited-area Ensemble Prediction System (LEPS), based on COSMO-model and implemented within COSMO (COnsortium for Small-scale Modelling, including Germany, Greece, Israel, Italy, Poland, Romania, Russia, Switzerland) implemented and maintained b ...

  6. A meso-scale ensemble system focusing on short range probabilistic forecasts and profiting from advanced multi-scale ALARO physics. Its main purpose is to provide probabilistic forecast on daily basis for the national weather services of RC LACE partners. ...

  7. A routine inter-comparison of wave model forecast verification data was first established in 1995, developed around the exchange of model forecast data at an agreed list of moored buoy sites at which instrumented observations of significant wave height, w ...

  8. The THORPEX Observing System Test, an experiment carried out at the end of 2003 to evaluate targeted observations in an Ensemble Prediction System. There is output from 3 different models, ECMWF, Météo-France and United Kingdom Met Office. Miscellaneous/S ...

  9. A set of experiments from four centres: ECMWF, Météo-France, EDF and Met Office. The experiments are 120 day runs from 9 consecutive starting days, with write-ups every 24 hours of Pressure level and Surface data. Miscellaneous/Special Access the MARS Cat ...
