1 ECMWF June 2006Slide 1 Access to ECMWF data for Research Manuel Fuentes Data and Services Section, ECMWF ECMWF Forecast Products User Meeting

2 ECMWF June 2006Slide 2 Introduction ECMWF makes data available for Research & Education freely or at a handling charge only For Commercial use, data is also available through Data Services (Archived and Real-time), with additional cost (information charge) This presentation focuses on data available for Research & Education Data access methods Data sets Data formats

3 ECMWF June 2006Slide 3 Data Access Services Archived or Real-time data: Meteorological Archival Retrieval System (MARS) Dissemination System Data Services Data from special projects: Public Data Server THREDDS/OpenDAP (experimental)

4 ECMWF June 2006Slide 4 MARS: Contents Main repository of meteorological data: Operational runs Deterministic Forecast: Atmospheric and Wave models Ensemble Prediction System Monthly Forecast Seasonal Forecast Monthly Datasets Monthly means Climatology Data from other NWP Centres

5 ECMWF June 2006Slide 5 MARS: Contents (cont.) Project Datasets ERA-15, ERA-40 PROVOST DEMETER Observations ECMWF Research experiments Member States experiments Using ECMWF models Using own models: COSMO/LEPS

6 ECMWF June 2006Slide 6 MARS: Access Direct access to more than 2 PetaBytes of data using pseudo-meteorological language Access modes: Batch Interactive: Metview, WebMARS Remotely from Member States Discovery (Data Finder) and Browsing (Catalogue) Restrictions to access valid data Users: Member States for Research & Education Access granted by NMSs

7 ECMWF June 2006Slide 7 Dissemination system Real-time products Subscription based Users edit requirement specification: which data (parameter, step, forecasting system, …) what post-processing (sub-area, grid, resolution, …) Product generation All products are generated in parallel on the supercomputer Data is pushed from ECMWF to users Operates under a fixed schedule Everyone gets same data at the same time

8 ECMWF June 2006Slide 8 Data Services Provide Data and Software to external organisations under rules approved by Council Data Services Catalogues Catalogue of Archived data and products Catalogue of Real-time products Software catalogue

9 ECMWF June 2006Slide 9 Data Services: Archive Catalogue Contents: MARS contents Access: On-line costing system ERA-15, ERA-40 Operational data Observations Marine, Aircraft, Vertical soundings Cost: Handling charge only for Research & Education Handling charge and Information charge for commercial use
