This presentation will focus on recent developments in climate reanalysis at ECMWF. We will explain the increasing role of reanalysis activities in operational products and services in Europe in the context of the Copernicus Program. Some results from the latest ECMWF atmosphere reanalysis, ERA5, will be presented. We will also discuss the approach to coupled climate reanalysis being explored for ERA6, to be produced in the next phase of Copernicus program.
