The content of some useful diagnostic files are as follows:
-cost_fn and grad_fn: These files hold (in ASCII format) WRF-Var cost and gradient function values, respectively, for the first and last iterations. However, if you run with NL_CALCULATE_CG_COST_FN=true, these values will be listed for each iteration; this can be helpful for visualization purposes. The NCL script WRFDA/var/graphcs/ncl/plot_cost_grad_fn.ncl may be used to plot the content of cost_fn and grad_fn, if these files are generated with NL_CALCULATE_CG_COST_FN=true.

l/plot_cost_grad_fn.ncl may be used to plot the content of cost_fn and grad_fn, if these files are generated with CALCULATE_CG_COST_FN=true.
Note: Make sure that you removed first two lines (header) in cost_fn and grad_fn before you plot. Also you need to specify the directory name for these two files.
gts_omb_oma: It holds (in ASCII format) information of all observations that got passed in WRF-Var. Each observation has its observed value, quality flag, observation error, observation minus background (OMB), and observation minus analysis (OMA). This information is very useful for (both analysis or forecasts) verification purposes.
namelist.input: WRF-Var input namelist file. It displays all the non-default options which user defined. If any of your namelist defined options did not appear in this file, you may like to check its name and match it with the WRFDA/Registry/Registry.wrfvar.
