Due to a recent change in ECMWF's data access and usage policies, all registered RDA users can now access any ECMWF dataset hosted in the RDA.  This includes the both the ECMWF operational and ECMWF reanalysis datasets maintained in the RDA.  Please review ECMWF's specific "Terms of Use" for the dataset that you are interested in accessing for further details.  This can be accessed in the "Usage Restrictions" section of the dataset description page.
