<div dir="ltr">Dear gradusers,<br><br>I am interested to see the diurnal averages of surface temperature over saudi arabia. Actually I have 22 years 'ERA Int' data having 4 time steps in each day (6 hourly). I would like to calculate diurnal mean cycle such that I left with only 4 points to see on the graph. How to check it in grads.<br>
<br>Regards,<br><br>Mubashar<br>
