<p>Hi Dennis,</p>
<p><br>
</p>
<p>Thank you for your reply, and comments. We proceeded as you recommended, and then tried to visualize the output on a second NCL script. The end result could be seen on the attached .pdf file. A few thoughts on what we have found out so far:</p>
<p><br>
</p>
<ol style="margin-bottom:0px;margin-top:0px">
<li>We can process a single <i></i><b><i><span style="color:rgb(0,111,201)">wrfout_d01*</span></i></b> file at a time, with the
<i></i><b><i><span style="background-color:rgb(255,255,255);color:rgb(0,111,201)">Wrf_hrly_to_daily.ncl
</span></i></b>script. However when we have tried to process a <i></i><b><i><span style="color:rgb(0,111,201)">wrfout_d01*</span></i></b> file with multiple hours of data, we observe errors on the terminal screen and virtually no data on the resulting
<i></i><b><i><span style="color:rgb(0,111,201)"><a href="http://o3.day.nc" target="_blank">o3.day.nc</a></span></i></b> netcdf file. Also the script will not read multiple
<i></i><b><i><span style="color:rgb(0,111,201)">wrfout_d01*</span></i></b> single hour data files, and just pick and process the very last hour of such batch of data files.
</li><li>The visual output is very appealing, but it would be desirable to have a visual representation within the domain area of study</li></ol>
<p><br>
</p>
<p>Attached you will find the NCL scripts we have used, the resulting <a href="http://o3.day.nc" target="_blank">o3.day.nc</a> netcdf file, as well as the .pdf post-processed image. Also we would be glad to share the
<i></i><b><i><span style="color:rgb(0,111,201)">wrfout_d01* </span></i></b>files we have used so far, through Dropbox, if you think it might help.
<br>
</p>
<p><br>
</p>
<p>As before we do appreciate your help and feedback with this issue.</p>
<p><br>
</p>
<p>Best regards,</p>
<p><br>

<p>Hi Dennis,</p>
<p><br>
</p>
<p>Thank you for your quick reply. Upon your suggestion we downloaded the pre-compiled binaries of NCl 6.4.0 for our Linux distribution configuration , openSUSE Leap 42.1_x86_64, and thankfully got it to work.</p>
<p><br>
</p>
<p>We also used your script and and it work very well to give us an average of the ground level o3 values on a new netcdf file, as well as on the terminal screen. However for some reason the new NCL image appear to revert to polar coordinates, and not to the
original Lambert Conformal ones of the original wrfout_d01* file. <br>
</p>
<p><br>
</p>
<p>Below you will see the message which we received on our terminal screen:<br>

<br>
<br>
Also attached you will find the script as well as the pdf post-processed file from NCL 6.4.0. Please let me know if you think it might be possible to include the original map projection on the post-processed image, so as to visualize the average ground level

<p>Dear NCL Support,</p>
<p><br>
</p>
<p>We are trying to find a script that <span>would read 24 individual 1-hour wrfout_d01* output files for every day of an entire month of the year, then </span>average the individual hourly ground level ozone (o3) concentrations data over each daily 24-hour
period (at lowest level nl=0), and write a new netcdf file with an gridded o3 average concentration for that specific day. The end result would be a visual representation of a gridded o3 average concentration for any specific day, if possible. </p>
