List,<br><br>I am having a bit of trouble setting up and using a template control file to display grib formatted model data. I've never used a template before (I've always used an individual control file for each hour's worth of forecast data) so this question may seem rather trivial. A similar question was asked a few months ago, but I didn't see a response that helped me out.<br>
<br>I've got 36 hours worth of grib1 model data and would like to use a template instead of opening 37 different control files. The naming convention of the files is as follows:<br><br>YYMMDDCC_arw_d01.GrbFHHHMM <br>
<br>(pretty straightforward, but YYMMDD is the 2 digit year/month/day of the run and CC is the 2 digit cycle of the run (i.e. 00, 06, 12, 18). YYMMDDCC stays constant for each file. Of course HHHMM is a 3 digit forecast hour and 2 digit minute which always happens to be 00).<br>
<br><br>I've set up my control file as follows: (I hard-coded the 06 cycle time into the template for now)<br><br><pre><font size="4">dset /usr/local/archive/grib_out/%y2%m2%d206_arw_d02.GrbF%f300<br>index indexfile <br>
OPTIONS template <br><br><font size="2"><span style="font-family: arial,sans-serif;">When I run gribmap -v -i template.ctl, the 00 forecast hour works fine. As a matter of fact, </span><span style="font-family: arial,sans-serif;">the first 17 files work just fine. However hours 18 to 36 fail because it's <br>

As a workaround, I tried using CHSUB 1 37 08040206 and putting %ch in place of the %y2%m2%d206 and that solved the problem. <br>
<br>My question though is how can I stop it from advancing the date incorrectly and if that can't be done, is there any way I can pass in the CHSUB section as an argument when I open the template control file? My template control file works fine, as long as I go in ahead of time and manually change CHSUB to the run I'm interested in. That's not really ideal though....<br>
<br>Any help would be greatly appreciated!<br><br>Thanks!<br>Dan<br>
