<div dir="ltr"><div>I suggest you convert the specific longitude values in your control file that are in the western hemisphere to negative values (negative longitude implies it's in degrees west). Then a command in grads like "set lon -44 30" should work. The error with your (1) is to be expected - Grads does not want to see the first number greater (i.e., to the right on the real number line) than the first number, even if it represents a legitimate west-to-east longitude band.<br>
<br></div>To avoid the seg fault, try running this line-by-line (i.e., by typing the commands by hand at the Grads command prompt instead of running a script). It seems likely that some other line of your script (not related to the current problem) is causing the seg fault.<br>

<br>
Try:<br>
<br>
Set lon -170 190 [or whatever you want the domain to be.
Negative values of lon are fine before the display command.]<br>

Thanks for your response.<br>
<br>
</div>
So I tried 3 things:<br>
<br>
1)<br>
</div>
set LON 320 25 <br>
</div>
and got the following error and the same plot from the
previous email appeared:<br>
Operation error: Invalid dimension environment<br>
Min longitude > max longitude: 320 25<br>
DRAW error: Syntax is DRAW STRING x y string<br>
<br>
</div>
2) set LON 0 360<br>
</div>
the entire area chosen for plotting was shaded.<br>
</div>
See attachment<br>
</div>
At the fourth iteration the code went to a segmentation fault.<br>
</div>
Because of the segmentation fault I was unable to execute the q
dims command afterwards<br>
<div><br>
</div>
<div>However upon opening the test.ctl in a new grads section I
got the following:<br>
LON set to 315.172 29.8276<br>
LAT set to -22.1706 22.1706<br>
LEV set to 1 1<br>
Time values set: 2010:4:8:0 2010:4:8:0<br>
E set to 1 1<br>
<br>
</div>
<div>What could be done to alleviate this isue?<br>
<br>
</div>
<div>I know the model domain is correct. See the second attached
figure plotted for quick look with ncview.<br>
</div>

<div>Jonathan,<br>
I would try defining your longitude values as negative
in the western hemisphere to positive in the eastern
hemisphere.<br>
<br>
</div>
What happens if you try 'set lon 0 360' and displaying?
Does it extend to the other side of the world and plot
your fields? Check 'q dims' after plotting and see if it
shows negative longitude values.<br>

<div>Hello:<br>
How do I get my WRF v3.5.1 model simulation to
plot west of the Prime<br>
Meridian? My domain is 44 W to 30 E and 22 S to
22 N. I have<br>
attached a figure that shows the iniability for
grads plot beyond 0 E.<br>
<br>
This is the case for a couple versions of grads:
2.0.1 and 2.1.a2<br>
<br>
I have also attached the script and ,ctl file that
I am using for this plot.<br>
