Gb. Raga et Pr. Jonas, ON THE LINK BETWEEN CLOUD-TOP RADIATIVE PROPERTIES AND SUB-CLOUD AEROSOL CONCENTRATIONS, Quarterly Journal of the Royal Meteorological Society, 119(514), 1993, pp. 1419-1425
Microphysical observations obtained in cumulus clouds over the sea are
presented and related to background pollution levels. The sub-cloud a
erosol concentrations vary from 50 to 5000 cm-3, which can hardly be c
onsidered 'maritime'. Observed droplet size distributions are used to
determine radiative properties using Mie theory. Functional expression
s are derived for the extinction cross-section and the single scatteri
ng albedo as functions of the sub-cloud aerosol concentrations.
