3.5.3. TRISONICAWS

3.5.3.1. Introduction

TriSonica MiniWS manufacturered by Anemoment, a compact and lightweight 3D ultrasonic anemometor. It functions using ultrasonic acoustic waves. It can measure temperature and humidity as well as wind in three components. One was deployed at IMU for over a year from September 2018.
