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. 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. 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 ...

  5. These products are only accessible for NMHS of WMO members under the following  conditions. These products are only available with a 0.5 °  by 0.5 °  grid. Similar products with higher spatial and temporal resolutions are available for other users, howeve ...

  6. 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 MARS Catalogue 🔒 ECMWF Member States ECMWF MARS Catalogue (restricted) ...

  7. 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 ...

  8. 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. ...

  10. 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 ...
