Hi,

First of all thanks for your valuable guidance and response. Here the two
figures are attached. In Fig-1 the plot is okay but in the Fig-2 there are
missing contours. These two figures are created at different times from the
same wrf output. For interpolating the wrf data I used (rcm2rgrid) NCL
function and for vertical interpolation used the function given below:

  plvl = int2p(theta(time|:,lat|:,lon|:,lev|:), \

 ; p(time|:,lat|:,lon|:,lev|:), lvl,0)

  plvl = int2p_n(theta, p,lvl,0,1)

  plvl = int2p_n_Wrap(theta,p,lvl,0,1)

After testing several times they produced the same results as shown in
(Fig.1 & 2)

There are many vertically and horizontally cross sectional examples are
available on the WRF site but Iím interested to plot the figure (as I
attached).

So I would like to know what is the reason either the code is not correct or
something else/ data missing problem? Print VarSummary (plvl_r) is attached
herewith.

Please your suggestion and comments will be highly appreciated.

Thanks and regards,

wei
