Inorganic-Aerosol

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).

Equilibrium constant parameterized by Equation 5 of Fountoukis and Nenes (2007): log K(T) = log K(T0) + H_coeff*(T0/T - 1) + C_coeff*(1 + ln(T0/T) - T0/T), where T0 = 298.15 K. Migrated from Aerosol.jl@c8c640bb src/isorropia/equilibria.jl:5 (`EqConst` @component). Parameters logK0, H_coeff, and C_coeff are reaction-specific values from Table 2 of Fountoukis and Nenes (2007). T is an input (driven by parent EquilibriumConstants in the coupled system); logK_eq is an algebraically observed output.

Aggregated equilibrium constants for ISORROPIA II. Composes 27 EqConst sub-components (r1...r27) from Table 2 of Fountoukis and Nenes (2007). Each ri.logK_eq(T) = logK0_i + H_i*(T0/T-1) + C_i*(1+ln(T0/T)-T0/T). A single T is broadcast to all subsystems via coupling equations.

A solid-phase aerosol species placeholder in the ISORROPIA II inorganic thermodynamic equilibrium model. Holds the molarity of a single solid salt in air. In isolation the concentration is conserved (D(M)/dt = 0); source and sink terms are added through the coupling mechanism when Solid instances are composed into the full Isorropia system. Reference: Fountoukis and Nenes (2007), ISORROPIA II.

Aggregate container for the 19 solid-phase salt species in the ISORROPIA II inorganic thermodynamic equilibrium model. Composes 19 named Solid instances — one per solid salt that can form in the K⁺-Ca²⁺-Mg²⁺-NH₄⁺-Na⁺-SO₄²⁻-NO₃⁻-Cl⁻-H₂O system — into a single subsystem bundle. Each Solid carries a single state variable M(t) [mol/m³] representing the molarity of that salt in air; in isolation M is conserved (D(M)/dt = 0). Source/sink terms are injected through the coupling mechanism when Solids is composed into the parent Isorropia system. Reference: Fountoukis and Nenes (2007), ISORROPIA II.
