Hi Elizabeth: I am not certain what tools you have access to, so this may not help you. If you have ncdump and ncgen, do an ncdump -h on your three files, and redirect the the output to files. Choose anyone of the files, and edit in the missing latitudes from the other files, making sure they are in order. call that say combine.cdl. Now use ncgen to create a new netcdf file from the combined cdl file, and then any of the steps you described should work. If this isn't making sense, if you cna at least get the header info from the 3 files and send them to me, i will send you an empty (except for dimensions) netcdf file that you can then populate with data. -Roy On Dec 18, 2011, at 2:39 PM, Elizabeth Crisfield wrote: > I have three files with the same variables, same longitudinal dimension, and > same time dimension, but different latitudinal dimensions.
