Anemoment Unveils New 3D Sonic Anemometer

By Anemoment LLC | August 17, 2021

Atlanta, GA(AUVSI XPONENTIAL, August 16, 2021) – Anemoment LLC, (Booth 2230) a specialized meteorological instrument design firm located in Longmont, CO, announced today the release of its newest 3D sonic anemometer, the TriSonica™ Sphere Wind Flux Sensor (Figure 1). Engineered to deliver more precise vertical wind measurements, coupled with faster sampling rates (up to 50 Hz), the TriSonica Sphere is ideal for UAS-based atmospheric flux and turbulence research, including eddy covariance studies.

Developed in conjunction with BlueHalo, a leading provider of advanced engineering solutions and technology to the national security community, the TriSonica Sphere was specifically engineered for deployment atop BlueHalo’s Atmospheric Characterization Payload (WP-V3 ACP) UAS sensor suite (Figure 2). The WP-V3 ACP is a complete, customizable meteorological sensor suite for making low Earth atmospheric measurements from a wide array of UAS platforms.

“The TriSonica Sphere's unique spherical implementation (patent pending) dramatically reduces the effects of wind shadowing and increases the accuracy of vertical wind measurements,” emphasizes Stephen Osborn, Chief Technology Officer and Co-founder of Anemoment, LLC. “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.”

“Anemoment’s sensors have been our preferred sonic anemometer since we discovered their TriSonica Mini Wind and Weather Sensor,” states Alex Clark, Senior Engineer, BlueHalo. “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.”

The TriSonica Sphere is available directly from Anemoment. Complete specifications and order inquiries can be facilitated on the company’s website:
