 The md5 checksum hashes were obtained by using the following python setup

-Currenly the checksum don't match between gfdl-ws and gfdl-pan for 1/4 and 1/8 degree grids (ocean_hgrid_res0.25.nc and ocean_hgrid_res0.125.nc )
+The tests were run on gfdl-ws , gfdl-pan-* using the same python executable and environment as shown above!
