82!   RFo: I do not know whether it makes sense to have 'constant_csflux=.TRUE. for only these species where
83!        no flux is given in the namelist. Let's choos surface_csflux=0.0 (and thus 'constant_csflux'=.TRUE.) as default
84!       To obtain  constant_csflux=.FALSE., set surface_csflux = 9999999.9 in the namelist
85!   @todo: need to think a bit more about constant_csflux for chemistry.
