I would think a simple "d max(tmp2m,t=(first),t=(last))" command should work. Granted, make sure you have your horizontal domain set to the entire globe.<br><br>Jeff Duda<br><br><div class="gmail_quote">On Mon, Oct 26, 2009 at 6:16 PM, Kevin M Levey <span dir="ltr"><<a href="mailto:klevey@customweather.com">klevey@customweather.com</a>></span> wrote:<br>

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>
