Hi Tim:
NCEP NAM CONUS_12km is not a lat/lon grid, you need to use the projection
described by the attributes of the Lambert_Conformal variable:
grid_mapping_name: "lambert_conformal_conic"
standard_parallel: 25.0
longitude_of_central_meridian: 265.0
latitude_of_projection_origin: 25.0
earth_shape: "Earth spherical with radius of 6371229.0 m"
If you are using Java, you can use the netcdf-java library for this.
