When you use a function (eg: dim_rmvmean) in any language, you should read
the function documentation. The short description is:

"Calculates and removes the mean of the (rightmost) dimension at all other
dimensions."

No SODA data is locally available. I assume your variables are ordered

   x(time,depth,lat,lon) or y(time,lat,lon)

So the rightmost dimension is 'lon' .... I am sure this is *NOT* what you
want.

[3]
How can a response be made when you provide no information on the contents
of the file?
Specifically,  the 'D20' variable. Does this contain daily, pentad, monthly
or annual values?

%> ncdump -h ....

or, equivalently

%> ncl_filedump ...


[4]
Anomalies from what? An overall mean? Anomalies from each  climatological
daily, monthly (ie, Jan, Feb,...) average?

Please respond to ncl-talk at ucar.edu
