ECMWF ERA-40 Re-Analysis Observations

BADC Data Extractor

The ECMWF now provides its own BUFR decoding software (BUFRDC) free from the ECMWF software pages. Documentation on other external software packages that can read GRIB.

Documentation

When you register to use the ECMWF ERA-40 data we will tell you where to find the ECMWF documentation made available at the BADC. More details about the ERA-40 datasets held at the BADC are available on the following topics:

• Grid resolution types (i.e. horizontal resolution).
• Level types (i.e. vertical resolution).
• Parameters.

Other useful documentation includes:

• The ERA-40 Project Report Series.
• Extensive ECMWF documentation on the ERA-40 project
• The precipitation in ERA-40 Report as part of the GEWEX-GPCP Workshop on Precipitation Analysis (ECMWF, March 11-13 2003, see page 42).
• Monitoring the ERA-40 production (including plots and validation information on observations, assimilation and analyses).
• Background to the ERA-40 project.
• The ERA-40 Project Plan (postscript file).
• The ERA-40 Archive Plan detailing products (postscript file).
• ECMWF Newsletter (Summer/Autumn 2004) containing a lengthy article about ERA-40.
• Proceedings from the Workshop on Re-analysis, November 5-9 2001.
• The ERA-40 Atlas, describing the climate during 1979-2001, is available from the ECMWF web site.

There is also documentation available via our ECMWF Operational data web pages detailing the Integrated Forecasting System that is used for operational forecasts. An ECMWF document entitled The description of the evolution of the ECMWF forecasting system and corresponding archive (published November 1999) is also available in .pdf format.

Links to further information

We maintain a set of links to ECMWF-related information on the World Wide Web, including the ECMWF home page.

The BADC holds other ECMWF datasets: ECMWF Operational data, ECMWF ERA-15 Re-analysis data and ECMWF trajectory data.

The BODC also has instrumentally recorded wave data available through their National Oceanographic Database, see here for further information. These data should be of interest to those users using the ERA 40 wave data held here at the BADC. Their holdings include entries for directional wave spectra, one-dimensional wave spectra and short-term statistics.
