I am attempting to consume this NETCDF file
http://www.mtnweather.info/download/wrfout_d01_2015-05-14_15:00:00.gz (I unzip
it before attempting to create a store). Upon doing so I receive an exception
shown below (somewhat abbreviated). My question is, is there any way to
overcome this exception allowing creation of a store from this file? Maybe
through configuration, or hints?
