shl,
This type of concatenation is done easily and intuitively in NCL,
and probably several other math and data handling languages. I
would prefer to tell you about the NCL method. Do you have a
working copy of NCL installed?
If not, there is an easy kludge. I do not like to recommend this
because it is kludgey. However it is reliable, and frequently it
gets the job done with least effort.
You can convert the latitude dimension into a record variable with a
command line trick, manipulate the dimension line in the ncdump/CDL
text version of the Netcdf file. In your case you can even just do
it with a text editor because you have only four small files.
Then use ncrcat to concatenate the four subset files together, along
the latitude dimension, as you have already surmised.
Please see my netcdfgroup post of 2007-nov-28, "Converting record
dimension to non-record dimension", for an example of this method.
In your case you are going the opposite way, from non-record to
record, so change the control strings accordingly. HTH.

So, it seems like I should be able to use the ncrcat function to concatenate
the files... but that function requires that there be a record dimension.
I'm not entirely sure what that is...
It seems that I need for the latitude dimension to be a record dimension...
is there an easy way to make it such?
