<p>Wesley,</p>
<p>You can ftp down the grib file here using anonymous:</p>
<p>137.135.248.188</p>
<p>ARPEGE_0.1_SP1_37H48H_201512150000.grib2</p>
<p>PS: It's about 40 meg and I tested the ftp download successfully from a command line rather than gui client</p>
<p>Cheers</p>
<p>Brian</p>

Brian,

It would be much easier if you made your grib file available
<br />
</div>
<div>
by FTP. If the file is huge or is a proprietary forecast, you can
<br />
</div>
<div>
zero out the data by
<br />
<br />
</div>
<div>
wgrib2 file.grib -rpn 0 -grib_out file00.grb

<p>Hi,</p>
<p>I'm working with Arpège grib2 files. These should I think each contain up to 13 hourly forecast timesteps. If I run...</p>
<p><a target="_blank" href="http://g2ctl.pl">g2ctl.pl</a> -verf -b file.grib2 > file.ctl<br />gribmap -i file.ctl<br /></p>
<p>...I'm able to open the .ctl file in GrADS but it only has 2 timesteps. T1 seems to be the time the model was initialized and T2 the time of the first forecast step.</p>
<p><br /></p>
<p>If I try:</p>
<p><a target="_blank" href="http://g2ctl.pl">g2ctl.pl</a> -b -ts1hr file.grib2 > file.ctl<br />gribmap -i file.ctl</p>
<p>It opens ok in GrADS and the correct number of timesteps are present but they begin from the model initialization hour rather than incrementing from the time of the first forecast step. For example:</p>
<p>Model initialization: 0z 15/12<br />Forecast time range contained in the file is +37 hours to +48 hours after initialization</p>
<p>t2 = 1z 15/12<br />t3 = 2z 15/12<br />.. etc<br /><br />As a consequence, when I try to plot a variable the grid is undefined.</p>
<p><br /></p>
<p>What should I think be present is:<br />t2 = 13z 16/12<br />t3 = 14z 16/12<br />..etc</p>
<p>Any suggestions / ideas on what I'm doing wrong?</p>
<p>Thanks</p>
<p>BWG</p>
