GEWEX-RFA Data Set Description Before attempting to submit data, please read "How to Participate" (http://eosweb.larc.nasa.gov/GEWEX-RFA/documents/how_to_participate.html) and the "File Convention" document (http://eosweb.larc.nasa.gov/GEWEX-RFA/documents/data_format.html) for detailed instructions on the data submission process. Please maintain a copy of this form for each data product (defined by _ as in the "File Conventions" document) you submit to GEWEX-RFA, and submit an updated copy of the file with EACH upload. This file will serve as the documentation for the entire data product within the assessment effort. ------------------------------------------------------------------------ Project Title: GEWEX-RFA ------------------------------------------------------------------------ Data product name: ECMWF-ERA40_Ed001 1) Contact for scientific questions about data Name: Jean-Jacque Morcrette Address: Shinfield Park, Reading, Berkshire RG2 9AX UNITED KINGDOM Telephone: E-mail address: Jean-Jacques.Morcrette@ecmwf.int URL: 2) What is the name of the original archived data set from which this GEWEX-RFA subset was produced? ECMWF 40 Years Re-Analysis 3) Is the original archived data set currently available from another data center or web site? Yes If so, please list addresses or URLs: http://data.ecmwf.int/data/ 4) Brief data description: A reference or URL for the complete original archived data set documentation, followed by a brief summary of features of particular relevance to the RFA submission (such as gap filling method), is the preferred approach. (Items of interest: input data streams, name of algorithm used to produce data, start and end time of data, gaps in spatial or temporal coverage, and data quality issues, etc.). http://www.ecmwf.int/research/era/do/get/Reanalysis_ECMWF The first reanalysis at ECMWF was carried out in early 1980s for the First GARP Global Experiment (FGGE) year 1979, when ECMWF operations began. Two major ECMWF reanalyses have exploited the substantial advances made since then in the forecasting system and technical infrastructure. The first project, ERA-15 (1979-1993), was completed in 1995 and the second extended reanalysis project, ERA-40 (1957-2002), in 2002. Products of ERA-15 and ERA-40 have been used extensively by the Member States and the wider user community. They are also increasingly important to many core activities at ECMWF, particularly for validating long-term model simulations, for helping develop a seasonal forecasting capability and for establishing the climate of EPS (Ensemble Prediction System) forecasts needed for construction of forecaster-aids such as the Extreme Forecast Index. 5) History of updates and changes. If you resubmit a new version of any part of this data product to GEWEX-RFA, please use this space to record the reasons for the new submission (i.e., fixed error in ___ parameter; changed to area-weighted spatial averaging, etc.) Please specify the parameter(s) affected, new RFA number(s), and the date of the change. 6) Please provide a list of publications and journal articles pertaining to these data (if any); or a link to a bibliography for the product. http://www.ecmwf.int/research/era/do/get/publications Uppala et al., 2005: The ERA-40 re-analysis.
