35! - introduced namelist item chem_modules@emiss_lod as future
36! - replacement to chem_modules@mode_emis.  Currently keeping both
37!   for backward compatibility.  chem_modules@mode_emis will be
38!   depreciated upon migration of all dependent modules (e.g., salsa)
39!   to chem_modules@emiss_lod
