Coordiante System Issue - Earth's Radius

All,

 

            NetcdfDataset dataSet = NetcdfDataset.openDataset("C:\\Documents and Settings\\nelsonb\\My Documents\\ArcMap\\us057g1010t03a000000000");

            NetcdfDatasetInfo info = dataSet.getInfo();

            VariableEnhanced var = (VariableEnhanced)dataSet.getVariables().get(0);

            GridCoordSys grid = info.getGridCoordSys(var);

            ProjectionImpl proj = grid.getProjection();

            LatLonRect latlon = grid.getLatLonBoundingBox();

            LatLonPointImpl point = latlon.getUpperRightPoint();

            System.out.println(point.getLatitude());

            System.out.println(point.getLongitude());

 

I have the above code, the issue is that the netcdf methods use a pre-programmed (constant) radius for the earth, which is different than the one that my data models use.  As a result, the corner points are off by a few hundredths of a degree (which translates to about 1.5km).  Do you know how I can force the projection to use a different radius?
