Of course if I use apf00_%f3 it’ll stop once it hits hour 54 because then it goes to 3 hourly after that. <o:p></o:p></span></p><p class=MsoNormal><span

This, of course, assumes the interval is regular and that the 6-hourly data contains all of the 3-hourly data. I think for GFS output this is indeed true, but you should check a few time steps just to be sure.

How would I get the entire 1-144 hours of accumulated precip totals? Is there a better way of templating the data so it’s all combined or does it need to be kept separate because I’m dealing with different time series? I can’t seem to find any way to tally together the accumulated precip data once the time series changes from hourly to 3 hourly (and again for models that have 3 time series such as UKMO)<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Cheers, Mike<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p></div></div><p class=MsoNormal>_______________________________________________<br>gradsusr mailing list<br><a href="mailto:gradsusr@gradsusr.org" target="_blank">gradsusr@gradsusr.org</a><br><a href="http://gradsusr.org/mailman/listinfo/gradsusr" target="_blank">http://gradsusr.org/mailman/listinfo/gradsusr</a><o:p></o:p></p></blockquote></div><p class=MsoNormal><br clear=all><br>-- <o:p></o:p></p><div><div><div><div><div><div><div><div><div><div><p class=MsoNormal><span style='font-size:10.0pt'>Jeff Duda, Research Scientist</span><o:p></o:p></p></div><div><p class=MsoNormal>University of Colorado Boulder<o:p></o:p></p></div><div><p class=MsoNormal>Cooperative Institute for Research in Environmental Sciences<o:p></o:p></p></div><div><p class=MsoNormal>NOAA/OAR/ESRL/Global Systems Laboratory<br><span style='font-size:10.0pt'>Boulder, CO</span><o:p></o:p></p></div></div></div></div></div></div></div></div></div></div></div></body></html>
