<p>Hi Mary <br>
</p>
<p><br>
</p>
<p>Kindly see the script below which I use with the bash script to determine the average of 2M TEMPERATURE contained in the whole of WRF out directory. I intend to skip the first 12 hours (spin up time) and I also tend to plot the final average in one plot.
Kindly let me know if you can help me out <br>
