| Zusammenfassung |
| The ability of a particle to serve as a cloud condensation nucleus in the
atmosphere is determined by its size, hygroscopicity and its solubility in
water. Usually size and hygroscopicity alone are sufficient to predict CCN
activity. Single parameter representations for hygroscopicity have been
shown to successfully model complex, multicomponent particles types. Under
the assumption of either complete solubility, or complete insolubility of a
component, it is not necessary to explicitly include that component's
solubility into the single parameter framework. This is not the case if
sparingly soluble materials are present. In this work we explicitly account
for solubility by modifying the single parameter equations. We demonstrate
that sensitivity to the actual value of solubility emerges only in the
regime of 2×10−1–5×10−4, where the solubility
values are expressed as volume of solute per unit volume of water present in
a saturated solution. Compounds that do not fall inside this sparingly
soluble envelope can be adequately modeled assuming they are either
infinitely soluble in water or completely insoluble. |
