Scavenging of Aerosol by Falling Raindrops. Final Report, July 1, 1980-June 30, 1982

摘要

Work is reported on the redesign of a scavenging chamber in order to measure the collection efficiency of freely falling water drops for aerosol particles under conditions of controlled humidity. The humidity control has been installed and a new drop generator has been designed permitting formation of drops as small as 0.3 mm radius to fall through the apparatus. The generator for preparation of the AgCl aerosol particle has been rebuilt and particle size determination perfected. Problems remain in the analytical procedure for analysis of the uptake by the falling droplets of the AgCl and in humidity control in the chamber. Work along these lines is continuing as a separate project. (ERA citation 07:063475)
