Project Description

A major task will be to relate the various components of the pre-cloud aerosol spectrum to the spectrum of cloud droplets and drops; and then to determine if variations in the concentration of these aerosol components are related to variations in cloud microphysics. Of utmost importance will be determination of which components of the aerosol spectrum (if any) are the embryos for precipitation formation. All of these aerosol measurements are essential for testing all of the warm rain theories, including the dynamic theories. Measurements of the CCN spectra of the residues of cloud droplets from the airborne counterflow virtual impactor (CVI) will more directly relate CCN to cloud microphysics.
