Yes, your suggestion works just great, however, there is a caveat. Without templating my GFS GRIB2 files your suggestion was not possible. I merely used the new templating feature for g2ctl (<a href="http://www.cpc.noaa.gov/products/wesley/g2ctl.html" target="_blank">http://www.cpc.noaa.gov/products/wesley/g2ctl.html</a>) and then used your suggestion as in</div>

If templating is not used all GFS GRIB files have only one t value and t does not vary and no matter what I did, it would not work. Templating my GFS GRIB2 files actually has allowed me to process my data a lot faster overall too. </div>

Dear Grads users<br>
<br>
It turns out my current logic is not correct. I am trying to find the<br>
highest TMAX2m value for each point on the globe from four 6-hour GFS<br>
forecast hours and then plot this value, so that the single plot will<br>
show the highest value for each of the 720x181 data points from the<br>
0.5 GFS data covering a period of 24-hours. I know the answer is<br>
probably simple, but I seem to making this harder than it should be.<br>
Any help would be greatly appreciated.<br>
<br>
Thanks.<br>
<br>
Regards,<br>
