You can perhaps try the GDAL_NETCDF_BOTTOMUP=YES/NO configuration option. > > Do I need to reorganize the pixels to be in the range of -180 to 180? Not necessarily. GeoTIFF will accept any georeferencing. The choice of reorganizing the pixels or not depends on the expectations of the people/software using your GeoTIFF. > What is the best way t do this? > I can probably slice and splice the numpy array for each row as I copy > it.
