Hi Carl: The problem is that this file does not follow the CSM Conventions: http://www.cgd.ucar.edu/cms/eaton/netcdf/NCAR-CSM.html Among others things, its missing time and vertical coordinates. It doesnt appear we can do much with it, unless you have a Java programmer who can write a specialized "CoordSysBuilder": http://www.unidata.ucar.edu/software/netcdf-java/tutorial/CoordSysBuilder.html John.
