3D Sonic Anemometer for UAS-Based Atmospheric Research

Anemoment has released its newest 3D sonic anemometer, the TriSonica Sphere Wind Flux Sensor. Developed in conjunction with advanced engineering solutions developer BlueHalo, the new wind sensor has been designed to deliver more precise vertical wind measurements and sampling rates of up to 50 Hz. It is ideal for UAS (unmanned aerial systems)-based atmospheric flux and turbulence research, including eddy covariance studies.

The TriSonica Sphere has been specifically engineered for deployment atop BlueHalo’s Atmospheric Characterization Payload (WP-V3 ACP) UAS sensor suite. The WP-V3 ACP is a complete, customizable meteorological sensor suite for making low Earth atmospheric measurements from a wide array of drone platforms.

Stephen Osborn, Chief Technology Officer and Co-founder of Anemoment, commented: “The TriSonica Sphere’s unique spherical implementation (patent pending) dramatically reduces the effects of wind shadowing and increases the accuracy of vertical wind measurements. Our customers have been asking for a 3D sonic anemometer that can accurately measure atmospheric turbulence and flux measurements. The TriSonica Sphere not only delivers on those requirements but does so with a size and weight optimized for UAS deployments.”

Alex Clark, Senior Engineer at BlueHalo, said: “Anemoment’s sensors have been our preferred sonic anemometer since we discovered their TriSonica Mini Wind and Weather Sensor. The TriSonica Sphere retains the size and weight attributes we value for small UAS implementations, while providing us true 3D measurements of refractive index structure—key to measuring wind turbulence.”
