The sum of primary_particulate_organic_matter_dry_aerosol and secondary_particulate_organic_matter_dry_aerosol is particulate_organic_matter_dry_aerosol.  &quot;Net production&quot; means the net result of all chemical reactions within the atmosphere that produce or destroy a particular species.</description>
