GrADS is detecting the variable 'lev' as the Z coordinate for the internal grid, but all the variables have "level" in their dimension name lists, so they do not make the list of non-coordinate variables -- GrADS thinks they are on a different grid. <div>--Jennifer</div><div><br><div><br></div><div><br><div><div>On May 23, 2013, at 9:20 PM, Laura Zamboni wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Hi,<br><br>can you help me understanding why grads returns the following error:<br>"gadsdf: SDF file does not have any non-coordinate variables"<br><br>I've created an .nc file using Matlab that grads reads correctly but returns the error above when I add the "lev" dimension.
