Book Synopsis Automation of Visual Weather Observations by : H. Albert Brown

Available in PDF, EPUB and Kindle. Book excerpt: A study was performed to determine the feasibility of objectively and automatically determining two key components of an aviation weather observation: present weather and obstruction to vision. The automated system utilized was an instrumented tower and surface array of sensors located at the AFGL Weather Test Facility (WTF), Otis AFB, Massachusetts. The objective method consisted of a decision-tree program (AUTO) based on several uniquely different responses by these weather sensors to the same weather phenomena and on discrimination techniques using tower and surface instrument comparison. The ability of AUTO to monitor rapidly changing weather events and to discriminate different types of weather is demonstrated through selected hourly periods of observations taken at 1-min intervals. Hourly observations generated over a 14-month period, March 1978 through April 1979, are compared with FAA observations to determine the effectiveness of AUTO. Major areas of agreement were found in the discrimination of fog, haze, snow, rain, and no weather. Final results show that the FAA observations of the existence and non-existence of obstructions to vision and present weather were duplicated in 82 and 86% of the cases. Thus the acquisition of real weather for an aviation weather observation, a duty presently performed by a human observer, is obtainable through an objective decision-tree program using an automated sensor array.

Download or read book Evaluation of Selected Sensors for Automated Tactical Weather Observations written by Eugene Y. Moroz and published by . This book was released on 1982 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program was initiated at the Air Force Geophysics Laboratory to develop an automated system to provide accurate and timely measurements of temperature/dew point, winds, precipitation, pressure, visibility, and cloud height in a tactical bare-base airfield environment. An assessment was made of available meteorological sensors to determine their suitability to satisfy the requirements of such a system. Potential candidate sensors have been identified in all areas with the exception of visibility and cloud height. Under the current effort the following were completed: (1) translators were designed and built for AWS wind and temperature/dew point measuring sets in order to provide for automated operation; (2) intercomparison testing of a number of precipation gages was performed; (3) a hand-held laser rangefinder was evaluated for use as a cloud height measuring device; (4) a prototype tactical visibility meter (TVM) was designed, fabricated, and tested; and (5) the development of a preproduction version of the tactical visibility meter was initiated.

Book Synopsis Survey of Sensors for Automated Tactical Weather Observations by : Eugene Y. Moroz
Download or read book Survey of Sensors for Automated Tactical Weather Observations written by Eugene Y. Moroz and published by . This book was released on 1980 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current requirements for tactical weather systems at fixed and bare- base airfields necessitate an upgrading of meteorological sensor capability, system automation, and a range of data dissemination options. A program has been initiated at the Air Force Geophysics Laboratory to implement these objectives. In the first phase of this program, a survey of the state-of-the-art has been made for the identification of equipment suitable for such a system. Government inventoried instrumentation, as well as those from commercial sources, have been considered. Criteria to be used in sensor selection will include both accuracy and the ability to operate trouble free over a wide range of environmental extremes. When appropriate, in-house programs will be initiated to correct deficiencies. During the coming year, field tests and intercomparisons will be made of selected sensors. Instrumentation will eventually be integrated into an automated system with local and/or remote display of weather elements tailored to user requirements.
Book Synopsis Analysis and Specification of Slant Wind Shear by : H. Albert Brown
Download or read book Analysis and Specification of Slant Wind Shear written by H. Albert Brown and published by . This book was released on 1982 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind data have been analyzed to produce frequencies of occurrence of slant wind shear with respect to surface wind speed, time of day, vertical temperature gradient and wind shear direction differences. Slant wind shear (SWS) is a measurement that more closely approximates the shear encountered by an aircraft on takeoff or landing. It is computed as the wind shear between a higher level wind (in this study, 60 m) and the surface separated by a horizontal distance equivalent to that which an aircraft would traverse in descending or ascending that height. Additional study was also completed on the specification of slant wind shear along the runway through the use of an offset towersurface site system.

Book Synopsis Automated Low-cost Weather Observation System (ALWOS) by :
Download or read book Automated Low-cost Weather Observation System (ALWOS) written by and published by . This book was released on 1982 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary objectives of this program was to design a developmental model ALWOS for the lowest possible cost. Reliability and maintenance costs over the life of the system were considered in addition to the initial purchase and installation costs. To this end, field proven, off the shelf components were used wherever possible throughout the system. Another primary objective was modularity of design. The hardware and software were constructed to allow flexibility in interfacing a variety of sensors or adding additional sensors to measure new parameters. The ALWOS as configured at Dulles Airport is a low-cost and flexible system which can provide an automatic weather observation from the data acquisition, processing and display point of view, with the potential for good long-term system reliability. After a period of familiarization with the equipment and dealing with an assortment of system and sensor problems, the functioning of the system became relatively trouble-free. Evaluation of the ALWOS supports the generally accepted concept that automated, low-cost weather observation systems can indeed perform such a function given suitable sensing devices. (Author).
