Book excerpt: Accurate and timely visibility information is required by the Air Weather Service in support of Air Force tactical bare-base operations. The Air Force Geophysics Laboratory (AGGL) undertook a program to develop a tactical visibility meter (TVM) to satisfy this requirement. A prototype meter was designed and fabricated by Wright & Wright, Inc., Oak Bluffs, Mass. The meter measures the atmospheric scattering coefficient in the forward direction. Visibility is inferred from the measurement. The operation of the prototype meter was successfully demonstrated by AFGL in tests conducted at its Weather Test Facility, Otis AFB, Mass. In the next phase of the development, Wright & Wright, Inc., was tasked to design and fabricate a cost-effective preproduction version of the TVM. This report describes the current development, test, and evaluation of the TVM.

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 excerpt: A light-weight, compact nephelometer for the detection of cloud presence and the estimation of visual range was designed, fabricated, and tested. The device is intended for airborne deployment for use in a tactical weather observation system and in support of precision guided munition missions. The sensor is a fixed angle nephelometer utilizing an infrared diode at 0.88 micrometers and a silicon photovoltaic detector. The sensor was calibrated in an environmental fog chamber over a wide range of fog and haze conditions. The sensor was found to have a very wide dynamic range of sensitivity (over the decades of attenuation coefficient) and, within operational requirements for accuracy, its performance can be described by a universal algorithm. The nephelometer was field tested at AFGL's Weather Test Facility at Otis AFB; high correlations were observed with transmissometers and other forward-scatter meters.

Available in PDF, EPUB and Kindle. Book excerpt: A new visibility instrument, the forward scatter visibility meter, has been developed. This report describes the development of the instrument, including the various field tests. Some thirty instruments have been operationally deployed in a network of automatic weather stations near L.G. Hanscom Field in Bedford, Mass. Comparisons between field instruments and transmissometers yield differences of about plus or minus 19 percent. Comparisons with visual observations show differences of plus or minus 34 percent and greater. Analyses of individual cases uncovered difficulties with the response time of observers and with ability to diagnose spatially varying visibility. The accuracy of visibility measurements is assessed and the report concludes by looking at the future of visibility instruments. (Author).

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.
