The Vaisala LAP®-16000 Tropospheric Wind Profiler is a Doppler radar which provides vertical profiles of horizontal wind speed and direction, and vertical wind velocity up to an altitude of 16 km above ground level.  When the Radio Acoustic Sounding System (RASS) option is added, it can provide virtual temperature profiles up to 5 km. LAP®-16000 is configured for a particular site and operational requirements. The applications include for example synoptic upper air observations, special research programs, and space launch support.
