refine_vert with ndown.exe

[ankur572]

I am trying to refine my vertical levels from 40 to 52 in non-concurrent nested run and running nest one after another

So, I am using d01 wrfout to prepare wrfbdy_d02 using wrfndi_d02 and ndown.exe. If I am using refine_fact as 2 it works perfectly fine but I want 52 levels not 80 from 40, so just putting evert as 52 and refine method as '2'. But its not working. Do any one have any idea about this? For reference I have posted domain section of the namelist. Thanks!

Hi,
Unfortunately, the vertical refinement program for ndown is quite limiting and only works with vert_refine_method = 1 and vert_refine_fact = 2. There is a utility program (v_interp) that could potentially work for your needs.
