[gradsusr] Grid Dimensions CCSM3 TOS Variable

[Dustin Pittman]

I am having problems defining the ydef for the tos variable with the ocean
CCSM model. I have tried defining explicitly for all y levels and also with
various definitions of the gaussian grid according the the grads site. Below
is the relavent portions of the ncdump file from the netcdf file. Below that
is the concatenated ydef latitudes. I am using GrADS 2.0.a8 on a Mac OS X
10.6.7.

netcdf tos_O_MO_pmip2_0k_oa_CCSM-mocat-0050 {
dimensions:
lon = 320 ;
lat = 395 ;
 bnds = 2 ;
time = UNLIMITED ; // (600 currently)

double lon_bnds(lon, bnds) ;
