ncl_filedump is a command line utility. It operates like 'ncdump -h ...'<br>
<br>
It is not meant for use within a script<br>
<br>
---<br>
The same information is available within the script via<br>
<span class=""><br>
dir = "/atmomounts/home/grad/mserino/Desktop/"<br>
fil = "ruc2anl_252_20090605_2000_000.grb"<br>
<br>
; force a 'time' dimension<br>
<br>
setfileoption("grb","SingleElementDimensions","Initial_time")<br>
<br>
f = addfile(dir+fil,"r")<br>
</span> print(f) ; same info as: ncl_fildump<br>
-itime rucanl_252 ....grb<br>
<br>
[2]<br>
Well, it seems the software used has chosen a low level to begin the<br>
ascent of the parcel.<br>
The area enclosed by the sounding (black line and dashed red line) is<br>
quite large.<br>
Why this occurred, I do not know.<br>
