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.
Best,
Shane
