Thies CLIMA’s Ultrasonic Anemometer 3D (US3D) stands out – not only by measuring with scientific precision, but by proving it.

The US3D delivers IEC-certified accuracy for wind speed and direction across 360°, for tilt angles up to 45° and for wind speed up to 85 m/s. The proven accuracy meets the most stringent best-in-class meteorological requirements. We are proud that US3D is the first choice for weather services worldwide upgrading their measurement networks with 3D, high wind capable wind measurement devices.

Being in the market for 20 years and long-term field proven in all climate zones, US3D stands out with product maturity and a stable series production, which gives the product high reproducibility and reliability. The capture of 3D wind vectors enables turbulence analysis and flux measurement. An internal sampling rate of up to 285 Hz not only ensures that rapidly changing events such as gust fronts and wakes are recorded in detail, but also provides excellent data availability and consistency, even under the most disruptive conditions such as in a typhoon or in the dessert. Compatible with industry-standard outputs (analog, RS485, ASCII, NMEA) and many special features, the US3D integrates seamlessly into meteorological, aviation, and research systems worldwide.
