[vox-tech] Additional WRF Chem Problems and uncertainties on how to handle WRF Chem

[Ambroff Linden]

For that particular option, see -fconvert in the gfortran man page.
You can specify the representation of data files with
-fconvert=<representation>, where representation is one of:

* native (little-endian on your little-endian PC)
* swap (opposite of your systems binary representation)
* little-endian
* big-endian

For example, if you were passing "-convert big_endian" to your fortran
compiler, you should switch to "-fconvert=big-endian" for gfortran.

I'd be surprised if that's your only problem though. You might want to
look up the documentation for all of the options you are using with
the original target FORTRAN implementation. You can compare that with
the gfortran man page to find equivalent settings for gfortran.

I noticed I have several namelist! files in em, namelist.input and namelist.input.fire.    I tried merging the namelist.input.chem with namelist.input by copying all the chem components of namelist.input.chem into namelist.input and got the following error message:

Also do I have to use wrf_prep_chem program after downloading such data so that it can be used by the WRF model?  I read one article that discussed using TOMS data aerosol indices for such data.  Is that how I should approach things?  Could you please clarify how to handle the namelist. input files in WRF chem and what types of data I need and how to incorporate this data into the WRF model when modeling dust lofting and deposition in the WRF model, whether through using the GOCART m! odule or nbsp;
