Minus 40 to Plus 60 Degrees Celsius Onshore Wind Lidar with Sight Wind Speed Accuracy 0.1 Meters Per Second Supporting Wind Data Acquisition

Product Description:

The Molas 3D represents cutting-edge technology in the field of three-dimensional wind scanning lidar. It operates on the principle of pulsed laser coherent Doppler frequency shift, emitting pulsed laser beams and analyzing the frequency shifts of backscattered signals from atmospheric aerosols. This approach allows the device to accurately determine the line-of-sight wind speed and direction at multiple spatial points, enabling precise high-resolution reconstruction of the 3D wind field.

To meet a wide range of measurement demands, the Molas 3D supports multiple scanning modes:

• PPI (Plan Position Indicator): Performs horizontal sector scans or a full 360° sweep, ideal for constructing wind maps over extensive areas.
• RHI (Range Height Indicator): Executes vertical elevation scans that capture detailed vertical wind profiles and boundary layer structures.
• DBS (Doppler Beam Swinging): Utilizes multi-beam fixed-direction scanning to retrieve accurate horizontal wind vectors and vertical velocities.
• Program Scan: Allows users to define customized scanning paths tailored for specialized research applications.

The system boasts an impressive maximum acquisition distance of 15 kilometers, with effective sight detection at up to 10 kilometers altitude around 600 meters high. Vertically, measurements can reach up to 4 kilometers. Users can select from configurable distance resolutions of 15 m, 30 m, 75 m, or 120 m, supporting as many as 300 distance layers. Wind speed measurements cover a range from -75 m/s to +75 m/s, featuring high accuracy at 0.1 m/s. The scanning head offers full 360° horizontal rotation and vertical tilt from -10° to 190°, with a precise pointing accuracy of ±0.005°, ensuring consistent and reliable data acquisition.

The Molas 3D is engineered to serve a variety of demanding applications, including but not limited to:

• Offshore Wind Resource Assessment: Provides accurate wind mapping over marine areas where conventional meteorological masts are not feasible or too costly.
• Complex Terrain Research: Investigates wind flow characteristics over mountains, hills, and valleys to understand highly variable wind patterns.
• Wind Turbine Wake Detection: Visualizes and analyzes turbine wake deficits and turbulence for optimizing farm layouts and minimizing turbine fatigue loads.
• Airport Glide Path Wind Shear Warning: Offers early detection of dangerous wind shear conditions along aircraft approach paths to improve aviation safety.
• Urban Meteorological Observation: Measures wind dynamics within city canyons, aiding urban planning and pollution dispersion studies.
• High-Altitude Turbulence Detection: Monitors atmospheric turbulence at elevated altitudes, supporting both aviation and climate research efforts.

Designed for durability, the Molas 3D operates reliably in harsh environments with an operating temperature range from -40°C to +60°C, and tolerates humidity levels between 0% and 95% RH (non-condensing). Its housing is rated IP65, while internal components meet IP66 standards. Data storage capabilities allow local retention for 5 to 18 months in a standard .csv format. For data transmission, the system supports 1000BASE-TX Ethernet and 4G remote access. It also provides multiple output interfaces such as Profibus DP, Modbus TCP, and CAN, facilitating smooth integration with various control and data acquisition platforms.

Combining robust performance, versatile scanning functions, and wide application adaptability, the Molas 3D stands out as a premier solution for advanced wind measurement and atmospheric research. It empowers industries and researchers alike to make informed, data-driven decisions with confidence.
