UERRA, Uncertainties in Ensembles of Regional ReAnalysis, is a project related to meteorological observations funded under EU - Framework Programme 7. It includes recovery of historical (last century) data, estimating uncertainties in the re-analyses and user friendly data services. It aims to contribute to the future Copernicus climate change service.

The role of ECMWF is to create and host a data archive of selected meteorological fields for UERRA purposes.
