Howdy Corey! As Larry points out, netCDF-4 does not handle scalar numeric atts in HDF5 files. But this seems like something I should add. I have made this a ticket in our project management database, you can follow progress here: https://www.unidata.ucar.edu/jira/browse/NCF-56 I'm not sure when this improvement will take place. Thanks, Ed Ticket Details =================== Ticket ID: GSV-822191 Department: Support netCDF Priority: Critical Status: Closed
