Abstract: Measurements of the effectiveness of natural and artificial freezing-nuclei were carried out in a room-size cold chamber. The concentration of natural nuclei varied from approximately one per liter at about ?13C to 1000 ...

Abstract: Measurements of droplet size and visibility have been made at different levels above the base of all types of cumulus clouds. The evaluation of these data permits calculations of corresponding values of water content and ...

Abstract: Few would question such doggerel as ?no two snow crystals are alike and in infinite variety they fall.? Conversely, many might challenge the statement that individual crystals are relatively scarce by comparison with ...

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 ...

Abstract: Based on aircraft measurements of the radiant emittance of cirrus clouds and cloudless sky, the 8-13? infrared transmissivity of high cirrus clouds was calculated. The measurements and applied calculations were made for ...
