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
<DataProduct>_<ProductVersion> 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.

2) What is the name of the original archived data set from which this
     GEWEX-RFA subset was produced? N/A

3) Is the original archived data set currently available from another
     data center or web site? N/A
     If so, please list addresses or URLs:

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.).

     The results presented are an ensemble of coupled GCM expriments with differing
     initial conditions. These experiments start in 1860 and end in 2003; only 
     the results from 1983 onward are presented. They include temporal
     changes in gas amounts, aerosol amounts (including volcanic aerosols),
     and the solar irradiance at the top of the atmosphere.

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. 

     The results for the zonal/global and land/ocean time series were recomputed
     using the same land-ocean mask and latitudinal averaging scheme that is applied
     to the SRB global data set.

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.

     Delworth, T.L., and Coauthors (2006), GFDL's CM2 global coupled climate models. 
     Part I: Formulation and simulation charcteristics, J. Climate, 19, 643-674.

7) If you would like a specific citation or acknowlegment when these
     data are used in a publication, please provide that here:
     "These data were obtained from experiments using GFDL's coupled model, version CM2.1"
