Here, the model calculates the saturation vapour pressure of water, S, above an aqueous particle for a range of
water contents, taking into account the effect of surface curvature (the Kelvin effect). This is often
described as a "Köhler calculation", especially when the results are plotted as saturation against
wet particle radius. The calculation can also be carried out using the simplified κ-Köhler
equation (see ref. 1), by selecting the last of the options in section 1, below.
Inputs: temperature, the moles or masses of each solute species, or the dry particle radius
and volume fractions of its constituent solids.
Outputs: the critical supersaturation Sc (if any), and the properties
of the aqueous particle for a wide range water contents and radii.
Methods: either (E-AIM) or the κ-Köhler equation can be chosen
to calculate the properties of the particles.
