are using 35 vertical levels but I output both height and pressure levels for specific fields in different output streams which I think is why it appears that I’m only using 7 in the control file. I’ve attached my namelist for you to have a look at. Hopefully,
the answer will be apparent from there.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">I'm not familiar with using the WRF software package to directly take output from the native eta levels to isobaric surfaces without using some sort of post-processing. For the longest time I used either ARWpost
(now deprecated) or the Unified Post Processor (still supported) to interpolate raw output to isobaric surfaces. Therefore, I cannot directly explain to you why your error might be occurring. It might help if you showed us your namelist, specifically the entries
that control outputting in grib format. Right off the bat, however, i suspect at least part of the problem is the fact that you have only 7 levels of output, and you probably used more than 7 for your nz in your model run, so there could be a mismatch going
on.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">If we can't figure this out from the namelist, I would suggest asking wrfhelp about it. If that doesn't pan out, I would try the UPP. If that still doesn't work, I have some Fortran code that will write out
control files for your raw output.<o:p></o:p></p>

Grib2ctl appears to work fine and gives no errors but one of my variables appears on the same line as another in the control file initially, so I have to move it.<o:p></o:p></p>

increasing the value of s but to no avail. The data can be read in fine with wgrib. Does anyone know how to fix this issue? <o:p></o:p></p>
