[gradsusr] Issues opening GOES-16 NetCDF files

I've been able to plot them on version 2.1.1.b0; which version of
GrADS are you using?
Another option would be to create a GrADS control file for the
netCDF file; e.g.,
UNPACK scale_factor add_offset
TITLE ABI band 02 CMImesoscale sector
XDEF 2500 LINEAR 1 1
YDEF 1500 LINEAR 1 1
ZDEF 1 LEVELS 1000
TDEF 1 LINEAR 16:12Z07NOV2018 5mn
Brightness_Temperature=>CMI 1 y,x Brightness Temperature (K)
Note that this will plot the images on their native grid; I don't
know a way to remap them in GrADS if you want to plot them with a map on
top. Hope this helps...
