On the relationship between cloud water composition and cloud droplet number concentration.

ABSTRACT: Aerosol-cloud interactions are the largest source of uncertainty in quantifying anthropogenic radiative forcing. The large uncertainty is, in part, due to the difficulty of predicting cloud microphysical parameters, such as the cloud droplet number concentration (N _d). Even though rigorous first-principle approaches exist to calculate N _d, the cloud and aerosol research community also relies on empirical approaches such as relating N _d to aerosol mass concentration. Here we analyze relationships between N _d and cloud water chemical composition, in addition to the effect of environmental factors on the degree of the relationships. Warm, marine, stratocumulus clouds off the California coast were sampled throughout four s
