[ncl-talk] Cross sections w/ smoothed terrain.... New issue???

Hi, Scott --

I had not thought of that. Thank you so much for your prompt reply. I will try this tomorrow!

Best,
Kacie

Have you modified line ~382 in WRFUserARW.ncl yet?  dz can be decreased from the default value of 0.01:

...else
        z_max = max(z)
        z_min = 0.
; Changed to:
dz = 0.002 * z_max
        ; From:
        ;dz = 0.01 * z_max
        nlevels = tointeger( z_max/dz )
        z_var2d = new( (/nlevels/), typeof(z))
        z_var2d(0) = z_min
     end if

Hi NCL friends,

Attached is an image of the current output I am getting trying to plot a vertical cross section with WRF data in NCL. Also attached is my code, and I can upload the WRF data file for anyone who needs it.

I have used this script tons of times in the past with no issue (i.e. no "missing" data near the ground, or at least the terrain was smoothed to cover that up) and am hoping to figure out what's wrong.

Could it be the data file I have? If yes, is there a simple way I can extrapolate the RH values to below the ground?

Is it the version of NCL I am running?? I used to run this script in v6.4 but am using v6.3 at the moment.

A colleague of mine made a plot with the same WRF file in RIP and did not have this issue. I would prefer to plot this up in NCL if possible as I think the plots come out nicer and this is going into a document for some pretty important folks...

Thanks,
Kacie
