So, I just used the same variable but only typed out the first 15 characters of the variable name and it worked for me. In your case,
<span style="white-space:pre-wrap"> 'd MAXUVV400_1000mb'</span> would become:

It is an issue related to
the fact that grads does not support long variable names. To solve it: I
provided in control file an "alias" variable name that follows grads
rules like: <br></div><div>MAXUVV400_1000mb=>MAXUVV400</div><div>So I use the following commands to create this alias:</div><div><br></div><div>$<b> cat </b>201104270600_wrfout_arw_d01.ctl<b> | sed 's/MAXUVV400_1000mb/MAXUVV400_</b><b>1000mb=>MAXUVV400/g' > </b>new_wrfout_arw_d01.ctl</div><div>$<b> </b>mv new_wrfout_arw_d01.ctl 201104270600_wrfout_arw_d01.ctl</div><div><br></div><div>In this case if we look inside <b> 201104270600_wrfout_arw_d01.ctl</b>, we get:</div><div><b>
