Hi Shane:According to current spec, point data needs to have a (single) dimension, if you look at CF appendix H.1.
One could handle scalars as a special case, but it doesnt seem worth the complication.

Hi all, Using NetCDF-Java 4.3.20, point feature datasets with rank 0 time cannot be loaded. CFpointObs.getPointConfig checks the rank of the time axis and errors if it's not equal to 1. Should point datasets with a single non-varying time axis be supported? Dataset structure is posted below, sample file attached.
