Abstract: Koschmieder's formula is verified by experimental data obtained on Mt. Washington and is used to determine visibility in clouds from measurements of the scattering coefficient. Visibility in clouds varies from approximately ...

Abstract: With use of cloud data collected in all types of cumulus clouds, it is shown that the constant in the Trabert equation is not actually a constant but varies with the character of the droplet spectrum. Trabert's formula ...
