8.  creation details:
    The original T42 ozone data was created by running the PCM, using input data
    provided by Jean-Francois Lamarque (lamar@ucar.edu) and then feeding the 
    output into the MOZART model at 20 year intervals - 1890, 1910, 1930, 1950, 
    1970 and 1990.

    The output at those intervals is available (as of Feb 2004) on the NCAR MSS
    under /LAMAR/IPCC:
