John, I believe the problem is related to a work around in dg_subg to handle wrapping global grids by expanding the garea .5 degrees. As a short term work around, it appears you can use: GAREA = -90;.5;90;358.5 since it looks like that will yield 0 to 359 degrees. Thy that and see what you get... I'll look into a code solution for the longer term.
