29! - introduced namelist item chem_modules@emiss_lod as future
30! - replacement to chem_modules@mode_emis.  Currently keeping both
31!   for backward compatibility.  chem_modules@mode_emis will be
32!   depreciated upon migration of all dependent modules (e.g., salsa)
33!   to chem_modules@emiss_lod
34!
35! (ecc) 20190513 replaced nspec_out with n_matched_vars
