When reading NetCDF files the library logs in some cases many warning., e.g
13100724 [main] WARN ucar.nc2.iosp.hdf4.H4header - data tag missing vgroup= 536 EV_500_Aggr1km_RefSB_Uncert_Indexes 13100725 [main] WARN ucar.nc2.iosp.hdf4.H4header - data tag missing vgroup= 542 EV_500_Aggr1km_RefSB_Samples_Used 13100726 [main] WARN ucar.nc2.iosp.hdf4.H4header - data tag missing vgroup= 461 EV_1KM_RefSB_Uncert_Indexes 13100726 [main] WARN ucar.nc2.iosp.hdf4.H4header - data tag missing vgroup= 496 EV_250_Aggr1km_RefSB 13100726 [main] WARN ucar.nc2.iosp.hdf4.H4header - data tag missing vgroup= 505 EV_250_Aggr1km_RefSB_Uncert_Indexes 13100727 [main] WARN ucar.nc2.iosp.hdf4.H4header - data tag missing vgroup= 511 EV_250_Aggr1km_RefSB_Samples_Used
This already happens when readers are tested for their applicability to read the current file. In the end, Hdf4 is not used.
This is especially disturbing when executing the reader tests
