I can show how I use mine? Maybe they are not complex enough, currently I do not need to go beyond 3 levels. I have attached two CDL outputs. I will need 5 levels very soon, so if you want that output when done I can supply if requested. 2014-11-06 17:31 GMT+00:00 Mary Haley <haley@xxxxxxxx>: > We have the same issue as Tim, in that we haven't been able to find many > good examples of NetCDF-4 for test purposes.
