          14             : ! Jul 2011  F Vitt -- made avaliable to be used in a prescribed modal aerosol mode (no prognostic MAM)
          15             : ! Mar 2012  F Vitt -- made changes for to prevent abort when 7-mode aeroslol model is used
          16             : !                     some of the needed consituents do not exist in 7-mode so bin_fluxes will be false
          17             : ! May 2014  F Vitt -- included contributions from MAM4 aerosols and added soa_a2 to the ocphiwet fluxes
