Ground-based measurement technologies: Long-term observations using L-band wind profiler in Asia

Abstract

Wind profiler is a Doppler radar that can observe upper winds from the ground by receiving atmospheric turbulence echo. The Communications Research Laboratory (CRL) developed an L-band wind profiler and has been carrying out continuous wind observations at Koganei, Tokyo since 1993. Ministry of Posts and Telecommunications (presently, Ministry of Public Management, Home Affairs, Posts and Telecommunications) and CRL also installed L-band wind profilers at Bangkok, Thailand and Gadanki, India, and has been making wind observations in cooperation with the King Mongkut's Institute of Technology Ladkrabang (KMITL), Thailand and the National MST Radar Facility (NMRF), India. Seasonal and diurnal variation of winds and classification of rain type using those wind profiler data are shown in this paper.
