<div>The output is fine and I am able to display it using GrADS. However I can't seem to set the initial date and that the forecast times are always referred to as the anl(analysis) instead of the 9hr fcst and so on.</div>
<div><br></div><div>Running wgrib -v on the grib1 file produces the following(other lines are omitted of course) :</div><div><br></div><div>233:3785740:D=2010031709:WIND:sfc:kpds=32,1,0:anl:winds are N/S:"Wind speed [m/s]</div>

<div><br></div></blockquote><div><br>First, recall that <a href="http://lats4d.gs">lats4d.gs</a> is a script that the LATS extension (which is a bunch of low level commands to create netcdf/grib files). Mike Fiorino tells me that the lastest version of thr LATS extensionin opengrads can indeed do what you request. However, <a href="http://lats4d.gs">lats4d.gs</a> does not (yet) provide a command line switch for exercising this.<br>
<br> At this point you may be able to use wgrib to repair your grib1 file.<br><br> Arlindo<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
