Set correct namelist.input for metonly

Because you want to run real.exe with only the meterology, you should add these before ./real.exe:

            if [[ $FDDA_ON == 1 ]]; then
                fdda_args="$pyargs --grid_fdda=0"
            else
                fdda_args=""
            fi  

            python $pyprog tempmod --emiss_opt=0 --bio_emiss_opt=0 --restart=.false. $fdda_args

Why? What if you want to run just WRF with nudging? Then you would need to have FDDA on for that run of real.exe to generate the FDDA file. The purpose of --met-only is not just to let you split up creating the met files and chem files in separate jobs, but to allow the automation to be used for pure-WRF jobs.

OK. If you want to run just WRF with nudging, it's right to turn FDDA on. But, you need to turn biogenic emissions off before ./real.exe.

Problem summary

• The function of running WRF-Chem with met-only doesn't work. ./autowrfchem prepinpt works fine.

Steps to reproduce

• What input data you are using (which met data, emissions data, etc.) NARR, NEI, MEGAN and MOZBC
• What Python version and package versions are being used Python3.6
• What compiler was used to compile WRF/WPS intel-compilers/15.0.1
• Version of netCDF C and Fortran libraries used for WRF netcdf/4.3.3.1/
• Specific commands to execute to cause the bug/crash ./autowrfchem prepinpt met-only

Reason and solution

It's necessary to turn biogenic emissions and anthropogenic emissions off before ./real.exe.

Please upload geogrid.log, ungrib.log, and metgrid.log from the BUILD/PREPLOGS directory as well.
