/YEAGER/CHLOROPHYLL
  has all netcdf and ieeer8 and raw data for chlorophyll

8.  creation summary:

     The monthly chlorophyll distributions were provided by Carter Ohlmann,
     <carter@icess.ucsb.edu>, based on SeaWIFS data spanning the period of
     September 1997 to November 2001. Chlorophyll monthly distribution is provided
     over all ocean on a 1x1 degree resolution. There is no data available for sea
     ice covered oceans, and some regions have missing data due to clouds. To handle
     missing data (especially in the polar regions), a 1x1 topographic dataset is
     used to specify ocean points, with nearest-neighbor fill of missing data done
     twice, which fills isolated points and some points along ice edge. Next, all
     remaining points over ocean are filled with the value .05 mg/m^3, a value
     appropriate for ice melting conditions. Finally, all remaining (land) points
     are nearest-neighbor filled, which sets missing coastal values with reasonable
     chlorophyll amounts. The resulting filled data was interpolated to gx1 and gx3
     ocean horizontal resolutions.

10. code, scripts,
    namelists, etc, used
    to create this file:   /home/tempest/yeager/ccsm_forcing/CHLOROPHYLL/chloro_fill.run
                           idl routine for converting to netcdf & filling & writing
                           out into ieeer8 format.

    history:               Under direction of Bill Large, chlorophyll amount data was
                           initially obtained as ascii text files by Steve Yeager during
                           September 2002. Steve put these data into netCDF format.
                           During January 2003, under direction of Bruce Briegleb, Steve
                           filled and interpolated the data to gx1 and gx3 resolutions.
                           Carter Ohlmann was consulted via email for suggestions on the
                           filling and interpolation method.
