✦ Synopsis

Abstract

Microphysical observations obtained in cumulus clouds over the sea are presented and related to background pollution levels. The sub‐cloud aerosol concentrations vary from 50 to 5000 cm^−3^, which can hardly be considered ‘maritime’. Observed droplet size distributions are used to determine radiative properties using Mie theory. Functional expressions are derived for the extinction cross‐section and the single scattering albedo as functions of the sub‐cloud aerosol concentrations.

Aerosols have an effect on cloud droplet size and concentration, and thus affect the radiative properties of clouds. The purpose of this study is to develop parameterized equations between droplet number concentration (Nd) and total aerosol number concentration (N,) for use in numerical weather pred
