001 DIRECTORY STRUCTURE EXPLAINED                     first  22 NOV 2004
                                                      update 23 NOV 2004
                                                      update 03 DEC 2004
--- -------------------------------------------------------- -----------
On the GFDL Data Portal, CM2.0 Model output is stored as netCDF 
files in directories that are arranged as follows under 
http://nomads.gfdl.noaa.gov/dods-data/gfdl_cm2_0/

 ../gfdl_cm2_0/{GfdlExperimentName}/pp/{component}/{ts:static:av}/... 

Possible values for gfdl_cm2_0 "GfdlExperimentName": (i.e., 
directories under http://nomads.gfdl.noaa.gov/dods-data/gfdl_cm2_0/)
  CM2Q_Control-1860_d2
  CM2Q_Control-1990_e3
  CM2Q-d2_1861-2000-AllForc_h1
  CM2Q-d2_1861-2000-AllForc_h2
  CM2Q-d2_1861-2000-AllForc_h3
  CM2Q-d2_1PctTo2x_i1
  CM2Q-d2_1PctTo4x_j1
  CM2Q-h1_SresA1B_x2
  CM2Q-h1_SresA2_w2
  CM2Q-h1_SresB1_y2
  CM2Q-h1_Stable-2000_s2

The meaning of "pp" is post-processed, indicating that the raw output 
of the model has been processed to get it into the form being served.

Possible values for "component":
  atmos
  ice_interp
  ice_tripolar
  land
  ocean_interp
  ocean_tripolar
    Model output files for the ocean and sea ice model components are 
    available either on the native, tripolar grid used by those model
    components or interpolated onto a more regular, latitude x longitude 
    grid. The  horizontal grid locations of tripolar vs interp only
    differ north of ~65N.

Meanings of the directory names "ts", "static", and "av":
  ts - time series - model output files found under "ts" directories
     contain information for multiple time levels of a single variable.
     Most of the CM2.0 model output data served on the GFDL data portal
     is in time series form. Additional subdirectories located under
     "ts" are used to group data according to the time interval between
     the time levels of info contained in the file. They are...
     /ts/3hr     -> time levels of info are separated by 3 hours
     /ts/daily   -> time levels of info are separated by 1 day
     /ts/monthly -> time levels of info are separated by 1 month
  static - time independent - the relatively small model output files
    found under "ts" directories each contain a single time independent
    variable.
  av - (reserved but not currently used)

002 GFDL CM2.0 DATA AVAILABLE FOR TABLES A1a AND A1c         22 NOV 2005
--- -------------------------------------------------------- -----------
GFDL CM2.0 model output files from Table A1a and Table A1c have been
transferred to the GFDL Data Portal and are now accessible from
http://nomads.gfdl.noaa.gov/dods-data/gfdl_cm2_0/
These two tables account for ~100 GB of data.
Table A1a consists of monthly-mean 2-D atmosphere and land surface data.
Table A1c consists of monthly-mean 3-D atmosphere data.
(see http://data1.gfdl.noaa.gov/nomads/forms/deccen/available_data.html
for more info about the variables contained in the different tables)
As of 22 Nov 2004, monthly-mean atmosphere and land time series files
from Tables A1a and A1c are available for 10 GFDL CM2.0 model 
experiments.
