Download or read book Design and Operation of the Ceilometer Computer written by Herman Paul Meissner and published by . This book was released on 1960 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ceilometer computer has been developed to provide a display and electrical readout of cloud-height information for use with an automatic weather station. The computer receives an analog signal from the detector of a rotating-beam ceilometer, and determines the height at which cloud indications occur. A small magnetic storage drum contains ten minutes of cloud-height information which is continuously updated, and these data are analyzed for the following factors: Predominant cloud height over the past 10 minutes; Maximum and minimum height at which significant cloud occurrences were observed; Number of cloud observations up to a selected critical altitude. The computer is a wired-program machine constructed of transistorized plug-in packages. Several modes of manual operation have been incorporated for testing and maintenance purposes.
