The filename is called surfacedata.grb2.f000 to surfacedata.grb2.f240.<o:p></o:p></p><p class=MsoNormal>At the moment the only way I can think is to template the first 0-120hrs using surfacedata.grb2.f%f3 for the 3 hour intervals and then 126-240hrs also using surfacedata.grb2.f%f3 for 6 hour intervals. <o:p></o:p></p><p class=MsoNormal>The issue that I have is with accumulated precip – it’s a running total where I need to subtract APCPsfc(t=3)-APCPsfc(t=2) for example to get a value – this works fine if you’re within 0-120 or 132-240hrs but when I go to hour 126 (start of 2<sup>nd</sup> set of data for 6 hourly intervals), I’d need to subtract hour 120 which is in the first data set.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers, Mike<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
