Fountoukis-Nenes

Binary aqueous molality of an inorganic salt as a function of relative humidity, using the 5th-order polynomial fit from Table 7 of Fountoukis and Nenes (2007). The polynomial m_aw(RH) = (k_0 + k_1*RH + k_2*RH^2 + k_3*RH^3 + k_4*RH^4 + k_5*RH^5) * m_one is used in Equation 16 of ISORROPIA II to compute the ZSR water content contribution from each salt. Multiple BinaryMolality instances (one per salt) are composed into the Aqueous component. Migrated from Aerosol.jl src/isorropia/aqueous.jl BinaryMolality (esm-406).

Conserved total concentration of a single inorganic aerosol species (e.g. NH, Na, Ca, K, Mg, Cl, NO3, SO4) in the ISORROPIA v1 thermodynamic equilibrium model. The total concentration `total` is held constant over time (D(total)/dt = 0), representing the user-supplied input constraint: the total moles per unit air volume of that ionic group across all phases (gas + aqueous + solid). This component is instantiated once per tracked ion group inside the top-level Isorropia system. Migrated from Aerosol.jl src/isorropia/isorropia.jl `Species`.
