This error comes up often when using nc files from the IPCC -- you must provide all the time axis information to GrADS to make sure it is correct. <div>Jennifer<br><div><br><div><br><div><div>On Jan 26, 2009, at 12:45 PM, Henrique Barbosa wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Dear All,<br><br>I have a few netCDF files which use a 365day calendar.
