XDFOPEN For Nonstandard NetCDF File

[David G DeWitt]

Hi Folks,
I am trying to open a netcdf file that has an extra dimension, i.e. ensemble
member. Reading the documentation it appears that GrADS can handle this
with a comma delimited list for  the units parameter, i.e.

 VAR=>hist0   0   0,y,x   First historgram interval for VAR

is the example given in the documentation. For a variable with the
following ncdump what would this syntax look like:

float t2m(T, M, Y, X)

where:
T is time
M is ensemble member (the non-standard dimension)
Y is latitude
X is longitude

Thanks for any advice you can give me on this. I have tried what I thought
this would be and I clearly do not understand the example.

Dave
