Maximum Acquisition Distance 15km remote equipment with 01m per second sight wind speed accuracy ensuring data capture over long distances

The Molas 3D is an advanced three-dimensional scanning Doppler wind lidar that operates on the principle of pulsed laser coherent Doppler frequency shift. It emits pulsed laser beams and detects frequency shifts from backscattered signals returned by atmospheric aerosols. By analyzing these signals, the system accurately calculates the line-of-sight wind speed and direction at multiple spatial points, enabling detailed high-resolution reconstruction of three-dimensional wind fields.

This innovative system offers a variety of scanning modes tailored to meet different measurement needs:

• PPI (Plan Position Indicator): Provides horizontal sector or full 360° scanning, ideal for extensive wind field mapping over large areas.
• RHI (Range Height Indicator): Conducts vertical elevation scans, perfect for capturing vertical wind profiles and boundary layer structures.
• DBS (Doppler Beam Swinging): Utilizes multi-beam fixed-direction scanning to accurately retrieve horizontal wind vectors along with vertical velocity components.
• Program Scan: Supports user-defined custom scanning trajectories, granting maximum flexibility for specialized research applications.

The Molas 3D boasts impressive measurement capabilities, with a maximum acquisition range of 15 kilometers and a sight detection distance of up to 10 kilometers at an altitude of 600 meters. Its vertical scanning range extends up to 4 kilometers, offering configurable distance resolutions of 15, 30, 75, or 120 meters and supporting up to 300 distance layers. The wind speed measurement range spans from -75 meters per second to +75 meters per second, with a precision accuracy of 0.1 m/s. Equipped with a scanning head capable of 360° horizontal rotation and vertical tilt ranging from -10° to 190°, it ensures pointing accuracy within ±0.005°, thus providing highly reliable and repeatable data.

The system is engineered to serve a wide range of demanding applications, including:

• Offshore Wind Resource Assessment: Enables accurate wind mapping over marine environments where installing traditional meteorological towers is challenging or cost-prohibitive.
• Complex Terrain Studies: Effectively resolves wind flow patterns over mountainous, hilly, and valley regions where wind behavior is highly variable.
• Wind Turbine Wake Detection: Visualizes turbine wake deficits and turbulence downstream to optimize wind farm layouts and reduce structural fatigue.
• Airport Glide Path Wind Shear Warning: Provides early alerts of hazardous wind shear conditions along aircraft approach paths, enhancing flight safety.
• Urban Meteorology: Captures detailed wind dynamics within urban canyons, supporting city planning and pollution dispersion analysis.
• High-Altitude Turbulence Monitoring: Observes atmospheric turbulence at elevated altitudes, benefiting aviation and climate research efforts.

Built for reliability in harsh conditions, the Molas 3D operates within a temperature range from -40°C to +60°C and tolerates humidity from 0% to 95% RH (non-condensing). Its housing is rated IP65, while internal components comply with IP66 standards. Data storage options include local retention from 5 to 18 months in standard CSV format. Data communication is facilitated through 1000BASE-TX Ethernet and 4G remote access, with output interfaces such as Profibus DP, Modbus TCP, and CAN, enabling seamless integration with various control and data acquisition systems.

Combining robust performance, flexible scanning modes, and extensive application versatility, the Molas 3D stands out as a leading solution for sophisticated wind measurement and atmospheric research. It empowers industries to make informed, data-driven decisions with confidence.
