Remtech manufactures the Doppler sodar and the RASS. Its sodars remotely measure a vertical profile of wind speed, direction, thermal stratification and turbulence parameters (sigma W, sigma Theta) up to 400, 700 and 3,000m average altitude range depending on the sodar model. They are ideally suited for wind energy site assessment, airport safety (wind shear detection), for air pollution control and forecast, and site surveys (power plants). Military organizations use sodar in programs for weapons development, parachuting, landing on aircraft carriers as well as general flight testing. Remtech’s RASS remotely measures temperature profiles in the atmosphere.
