<div dir="ltr"><div>Hi Mary,</div><div><br></div>Thank you so much for this invaluable help! I compiled cnvgrib successfully and can't imagine having been able to do it otherwise. The key was those sneaky changes that need to be made for FFLAGS and CFLAGS in g2lib and w3lib respectively. For anyone else who might have this problem on a Mac, there were a couple other little things that I had to do to point the compilers in the right direction, such as copying libpng.3.dylib from /opt/X11/lib to /usr/local/lib and adding a few directories to my ~/.bash_profile so everything played nicely together.<div><br></div><div>The step-by-step instructions were great and I plan to use this as a reference for future times that I get stuck on an installation.</div><div><br></div><div><br></div><div>Best regards,</div><div>Colin</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Mar 17, 2018 at 2:53 PM, Mary Haley <span dir="ltr"><<a href="mailto:haley@ucar.edu" target="_blank">haley@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small">Hi Colin,</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">I was able to get the cnvgrib program to compile, but it did require some arm wrestling.

Hi Bian,<br>
<br>
I'm looking into this.<br>
<br>
Meanwhile, I see that your original data goes from -180 to 180, but the<br>
lower left corner and upper right corner of the destination grid was set to:<br>
<br>
Opt@DstLLCorner = (/ 0.25d, 0.25d/)<br>
Opt@DstURCorner = (/89.75d, 179.75d/)<br>
<br>
This is restricting your data in the longitude direction to go from 0.25<br>
and 179.75. Perhaps you meant for this to be:<br>
<br>
Opt@DstLLCorner = (/ 0.25d, -180.00d/)<br>
Opt@DstURCorner = (/89.75d, 179.75d/)<br>
<br>
However, this still doesn't fix the issue, so I'm looking into it further.<br>
I'm wondering if this is a missing value issue, because I noticed that your<br>
lat/lon has some missing values in it.<br>
<br>

When reading the whole array, subscripts are not needed. Just use whole<br>
array syntax:<br>
<br>
x = f->ppt<br>
<br>
You did not fix the mismatched _FillVallue problem that I mentioned<br>
before. You will need to either fix the file, or else add this kludge to<br>
make NCL properly recognize the missing values after they are read in:<br>
<br>
x@_FillValue := todouble (x@missing_value)<br>
<br>
With that fix, it looks like your <a href="http://ppt.nc" rel="noreferrer" target="_blank">ppt.nc</a> data file is pre-masked for a<br>
predetermined spatial area. To calculate a simple spatial average time<br>
series for all grid points within that predetermined area, just use a<br>
simple unweighted array averaging function:<br>
<br>
dim_select = (/ 1, 2 /) ; select lat and lon dims to average over<br>
spatial_aves = dim_avg_n_Wrap (x, dim_select) ; makes a 1-D time<br>
series<br>
<br>
Please read the function documentation for dim_avg_n and dim_avg_n_Wrap,<br>
for more details.<br>
<br>
If you need latitude weighting, or you need to select a smaller spatial<br>
area within the existing domain, then more code will be needed.<br>

Subject: [ncl-talk] Unable to set explicit levels on contour plot<br>

<br>
Hi all,<br>
<br>
I am trying to set explicit contour levels on a vertical cross-section plot<br>
however with no luck....<br>
<br>
I've tried both "ExplicitLevels" and "ManualLevels" settings but neither<br>
seem to work.<br>
<br>
I've looked at all sorts of examples online but can't seem to see why mine<br>
won't work<br>
<br>
I've attached my script. As well as two plots from 2 different WRF runs...<br>
I want to be able to compare these, but if I can't set the scale the same<br>
then it's difficult to compare....<br>
<br>
Does anyone have any idea as to why I can not set these levels?<br>
<br>
Thanks!<br>
<br>

Hi Nick,<br>
I think what is happening is that symMinMaxPlt is overruling your previous<br>
settings of cnLevels. Try uncommenting out these lines:<br>
res@cnLevelSelectionMode = "ExplicitLevels" ; set explicit contour levels<br>
res@cnLevels = (/ -12,<br>
-10.,-8.,-6.,-4.,-2.,-1.,1.,2.<wbr>,4.,6.,8.,10.,12./) ; set levels<br>
and then comment out the symMinMaxPlt line:<br>
;symMinMaxPlt(w, 14, False, res)<br>
<br>
If that doesn't fix it let ncl-talk know..<br>

Hi Colin,<br>
<br>
NCL cannot write GRIB data, so I'm afraid we can't help you there.<br>
<br>
But we might be able to help with the cnvgrib compilation issues. Usually<br>
these smaller programs aren't too difficult to compile. Are you getting<br>
some kind of error from it?<br>

Subject: [ncl-talk] Regridding Moving Nest WRF outputs<br>
Message-ID:<br>

<br>
Good morning,<br>
<br>
I'm trying to regrid from a WRF grid (curvilinear) to ECMWF grid<br>
(rectilinear). The issue is that my WRF outputs are now obtained using the<br>
Moving Nest configuration. Therefore, I have a new high-resolution domain<br>
(D02) for each time step (I attach an example of what I'm saying).<br>
When D02 was fixed at specific lat/lon coordinates (i.e., without using the<br>
Moving Nest configuration) I used the rcm2rgrid function. But I do not know<br>
if I can use the same function now.<br>
<br>
Thanks in advance!<br>
<br>
Regards,<br>
Lara.<br>
