Short summary
We present the new Binary Activity Thermodynamics (BAT) model, which is a water-sensitive reduced-complexity organic aerosol thermodynamics model. It can use bulk properties like O : C, molar mass, and RH to predict organic activity coefficients and water uptake behavior. We show applications in RH-dependent organic co-condensation, liquid–liquid phase separation, and Kohler curve predictions, and we validate the BAT model against laboratory measurements.
