as it travels through layers h

aving differing temperatures in the atmosphere. Software analysis of the changing velocity produces temperature and lapse rate data. Doppler processing of the signal received by a second radar antenna measures the lateral wi

nd drift of the sound pulse as it travels upward. This makes it possible to measure the wind speed and direction versus altitude. For risk assessment data, the system can easily measure temperature inversion phenomena. (A temperature inversion results from the air at altitudes being warmer than at ground level, a reversal of the neutral condition of temperature decreasing with altitude.

At ) The SODAR/RASS is becoming a widely used system where lower atmospheric sounding is important to operations. Users include manufactures in industry who need to monitor byproducts and plume dispersion, airports to determine wind shear, utility companies, research universities, meteorological offices, environmental consultants, private research facilities, military instal

Although lations and national laboratories such as Los Alamos National Labs, Battelle Pacific Northwest Labs, Aberdeen Proving Ground, and White Sands Missile Range.
