Slant Visual Range from Drop-Size Distribution

Abstract

This research investigated the feasibility of obtaining visual range and slant visual range by use of drop-size distribution. The results of Davies' equation for computing visibility from drop-size distribution were compared to known values and those obtained from Mie scattering theory based on a program developed by Kattawar and Plass. Next, Davies' equation was applied to a Marshall-Palmer drop-size distribution and a vertically varying distribution obtained from a program developed by Borchers. The Marshall-Palmer distribution and visibility agree with those from Borchers' work. Davies' method of obtaining visibility then was used successfully to compute slant visual range along a glideslope. The drop-size distribution at various levels along the glideslope was produced by Borchers' program.
