This book was released on 1982 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capability and performance of the AN/GMQ-13 Cloud Height Set, commonly referred to as the Rotating Beam Ceilometer (RBC), was reviewed. Included in the study is an assessment of its ability to meet specific requirements for automting the measurement of cloud field properties, that is, layering and cloud cover, through the application of the hierarchical clustering technique. It is concluded that a single RBC system cannot meet current stated requirements for cloud height measurement. An RBC with a 1600 ft baseline can meet the high altitude requirement but has difficulty with low ceilings that are also associated with conditions of restricted visibility. An RBC with a 400-ft baseline does well at low altitudes but is totally inadequate at high altitudes. An obvious compromise would be the deployment of two RBCS, or one projector and two receivers. The hierarchical clustering technique for the determination of cloud field properties was previously demonstrated in AFGL and AWS field tests. The resolution and accuracy to be obtained is a function of the number of ceilometers available, their orientation, and time averaging considerations.

Available in PDF, EPUB and Kindle. Book excerpt: This report surveys techniques for cloud detection to assess their suitability for meeting the requirements of the Automated Observation System (AOS). A microwave sensor is essential because of the requirements for observing cloud top heights and documenting multiple cloud layers. Wavelengths between 3 cm and 8.6 mm could be used for this application, and a detailed sensor design study is recommended to evaluate the availability, cost, performance, and reliability of components and systems. Pulsed or continuous-wave radars could meet most of the requirements, although measurements of cloud base with high accuracy at low altitude may be difficult with some pulsed systems. Keywords: Cloud base; Ceilometer; Cloud amount; Automated cloud observation; Remote detection; Ka band radar; X band radar; Lidar.

Available in PDF, EPUB and Kindle. Book excerpt: A “solid and informative” biography of one of the overlooked heroes of the Second World War (Wall Street Journal). Of the leaders of the American Army in World War II, Jacob Devers is undoubtedly the “forgotten four-star.” Plucked from relative obscurity in the Canal Zone, Devers was one of four generals selected by General of the Army George Marshall in 1941 to assist him in preparing the Army for war. He quickly became known in Army circles for his “can do” attitude and remarkable ability to cut through red tape. Among other duties, he was instrumental in transforming Ft. Bragg, then a small Army post, into a major training facility. As head of the armored force, Devers contributed to the development of a faster, more heavily armored tank, equipped with a higher velocity gun that could stand up to the more powerful German tanks, and helped to turn American armor into an effective fighting force. In spring 1943, Devers replaced Dwight Eisenhower as commander of the European Theater of Operations, then was given command of the 6th Army Group that invaded the south of France and fought its way through France and Germany to the Austrian border. In the European campaign to defeat Hitler, Eisenhower had three subordinate army group commanders: British Field Marshall Bernard Montgomery, Omar S. Bradley, and Jacob Devers. The first two are well-known; here the third receives the attention he properly deserves.
