Abstract: The application of ground-based remote-sensing systems for monitoring those meteorological parameters of importance in urban air pollution is discussed. Typical system considerations include an analysis of site characteristics ...

Abstract: Wind shear has long been recognized as one of the major aviation hazards in the airport environment. A principal source of dangerous wind shear is the thunderstorm gust front, a cold air outflow from the thunderstorm ...

Abstract: Temperature profiles measured with a radiosonde are compared with returns from an acoustic echo sounder throughout the height range 50?700 m. In general, the sounder records indicate the temperature inversion to be somewhat ...

Abstract: Wind shear has been recognized as a major aviation hazard in the airport environment. A dual, acoustic Doppler microwave Doppler radar system has been installed at Dulles International Airport near Washington, D.C., to ...

Abstract: The current state of aviation weather forecasting and its effect on weather-related aircraft accidents are reviewed. The authors predict that new approaches will be necessary if the technological gap is to be narrowed ...

Abstract: Three acoustic sounders, with antennas having vertically-pointed beams located at the vertices of a triangle about 300 m on a side, have been used successfully to calculate horizontal phase velocities of gravity waves in ...
