Revised parameterization to predict cloud droplet concentration and a retrieval method to predict CCN concentration - Supplement -

In our recent paper "Parameterization of the effect of cloud condensation nuclei on optical properties of a non-precipitating water layer cloud" (Kuba et al. 2003), we developed an approximation to predict the cloud droplet concentration as a function of the CCN concentration and the updraft velocity at the cloud base. This study improves on the approximation for convenience. In addition, this study proposes an approximation for higher updraft velocities than those in the previous paper.
