Abstract
Information on the height of the cloud ceiling, vitally important to airplane pilots, now may be obtained during the day as well as at night. The use of the “ceiling projector” has been extended to daytime measurements by means of a photoelectric detector developed by the National Bureau of Standards for the United States Weather Bureau.
