I have an output of a simulation with WRF with three nested domains (9 km, 3km and 1 km), from the 1 km output I want to generate lateral and initial conditions for a 200 m domain (0.2 km) using the ndown program. However, I would like this 200m domain to be more refined vertically, so I set vert_refine_method=2 and entered the eta levels I would like to use. The ndown namelist was configured like this in the domains section:
However, when I analyze the wrfinput_d02 file generated by ndown, the refinement is not applied, I continue with 45 vertical levels, equal the 1km domain. When I use refinement by a factor it works perfectly:
My question is: does the ndown program accept vert_refine_method=2?
