ECMWF ERA-40 Re-analysis project

Status: completed
Publication State: published
Abstract

The objectives of the European Centre for Medium-Range Weather Forecasts ERA-40 project are to produce and promote use of a comprehensive set of global analyses describing the state of the atmosphere, land and ocean-wave conditions from mid-1957 to August 2002. The ERA-40 project applies a modern Variational Data Assimilation technique (used in daily operational numerical forecasting at ECMWF) to the past conventional and satellite observations.

More Information (under review)


A number of partner organisations are also involved to assess the quality of the global analyses, they are:

  • the Hadley Centre for Climate Prediction and Research, UK.
  • the Koninklijk Nederlands Meteorologisch Instituut.
  • Meteo France, Centre National de Recherches Meteorologiques.
  • Max Plank Institut fur Meteorologie, Germany.
  • University of Reading, Department of Meteorology, UK
  • the National Center for Atmospheric Research (NCAR), USA.
In partnership with NCAR and NCEP (National Centers for Environmental Prediction, USA), the ECMWF has obtained a comprehensive archive of past observations to supplement its original observational archives running from 1979 to the present day. A Sea Surface Temperature/Ice dataset produced by the Hadley Centre and NOAA/NESDIS has been made available to the project through PCMDI (Program of Climate Model Diagnosis and Intercomparison, USA), which is also participating in the quality assessment of the products.
