Changes in polarization and angular distribution of scattered radiation during cloud formation.
Changes in radiation scattering due to changes in droplet size distribution during development of stratus clouds have been calculated. The development model of Neiburger and Chien was used to give the droplet size distribution at various stages. Mie theory was used to calculate the angular variation for both parallel and perpendicular polarization of incident radiation at 0.4880 micro, 0.6328 micro, 3.50 micro, and 10.6 micro. The marked variations in the nature of the scattered radiation as the droplet size distribution varies with time indicate the measurement of radiation scattering may be a useful method of studying cloud formation processes.
