If you wish to try NCL anyway, I think you will find it a valuable tool for other things. I like NCO but there still a few things it doesn't do. ;-)
Have you used NCL before? Here are introductory docs that may answer initial questions:
http://www.ncl.ucar.edu/get_started.shtmlNCL is usually best used with small scripts, rather than command line. Enter this (untested) test program first, to validate your NCL installation. In a text file, e.g. concat.ncl:
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
begin
print ("Start program.")
; Substitute your Netcdf file name and data var name
; in the following 2 lines. Paths allowed:
infile1 = "file_1.nc" ; name of first file
var = "value" ; name of common data variable
f1 = addfile (infile1, "r")
printVarSummary (f1)
print ("--------------")
v1 = f1->$var$ ; read section 1 data
printVarSummary (v1)
print ("Done.")
end
Run from the command line as follows:
ncl concat.ncl
Debug as needed. Common install problems are path to NCL command,
and value for $NCARG_ROOT. See docs. Get that working, and check
displayed summaries for consistency with the contents of file_1.
They should be similar to what you get from ncdump -h.
Feel free to ask (on-list please) if you run into problems. I will send the concatenation steps later; above is the hard part!

Alright, I've just installed NCL... would you mind walking me through this method? Thanks much for your help :)
