Hi Jim, Thanks for the quick follow-up. No, I have not tried removing that coordinates attribute from the geogridded variables, but I’ll consider that. The checker is a brand new checker developed by PO.DAAC over the last year. It also provides additional options for ACDD, but I didn’t have that option checked when I ran the compliance checker. Here’s a brief statement on the derivation of the checker, which is also available here: http://podaac.jpl.nasa.gov/podaac_uat The Metadata Compliance Checker (MCC) is an online tool and web service designed to check and validate the contents of netCDF and HDF granules for the Climate and Forecast (CF) and Attribute Convention for Dataset Discovery (ACDD) metadata conventions. It produces quantitative scoring for these convention attributes as HTML, PDF or JSON outputs. It also checks GHRSST version 2 data formats as applicable. It works with both user locally uploaded data and well as data that are accessible via OPeNDAP. The MCC is based on open source software originally developed by NOAA that has been extended with additional functionality and reporting.

The dump looks fine overall. Have you tried removing your 'coordinates' attributes from your data variables? It shouldn't produce an error to have the coordinate variables listed there, but it is also unnecessary since your coordinate variables are all 'true' coordinates and that attribute is intended to list auxiliary coordinate variables (ones that don't fit the pattern of a true coordinate variable).

I get this error for the time, lat, and lon variables. Attached is a screenshot of the error as provided by the PO.DAAC Metadata Compliance Checker tool, which is openly accessible here: http://podaac-uat.jpl.nasa.gov/mcc/ Also attached is a netCDF header dump of the data file in question. It seems as though the time, lat, and lon variables are not properly declared as coordinate variables, or their dimensions are somehow not recognized as such. Whatever the case may be, the CF literature doesn’t seem to shed any light in to why this might be the case. Also, in my own close examination of the variable metadata, nothing seems to be amiss with respect to these variables being declared properly as coordinate variables. Am I missing something? If anyone can shed more light on this, I would be most appreciative.
