Jonathan,<br>I don't see a PDEF line in either control file, but since co plots in ctl_plevs.ctl as you said, then I don't see anything immediately wrong with either control file or the script, but I do see the differences between them. Perhaps the fact that you are using some positive and some negative longitudes in one control file and all positive longitudes in the other is making a difference, although I see you have set lon to be consistent with the control file you are using. Is there any error message that accompanies the display? Does co display if you just open the bb_plevs.ctl file and immediately enter 'd co'? If there is no error message I would tend to think there was a mis-specification of your lat/lon values either in the control file or in your script. <br>

<p class="MsoNormal">I have attached a grads script that plots WRF-Chem output of carbon monoxide (co) on the 850 hPa level co_850hPa_sequence.gs for a sequence of times. When the ctl_plevs.ctl (attached) is open, the grads plots the data correctly. However, when bb_plevs.ctl (attached) is open, the script does not plot the data. I do not think the actual WRF-Chem netcdf output is corrupt because I am able to look at it with ncview. This output appears to be fine. The problem I have described above happens with grads 2.0.a8 and 2.0.1. Moreover, this error happens with bb_plevs.ctl created by ARWpost v2.2 and v3, even after recompiling them a couple of times.<u></u><u></u></p>
