Product Description:

The Molas 3D represents a cutting-edge three-dimensional scanning Doppler wind measurement lidar system. It operates on the principle of pulsed laser coherent Doppler frequency shift technology. By emitting pulsed laser beams and analyzing the frequency shifts of backscattered signals from atmospheric aerosols, this system accurately determines the line-of-sight wind speed and direction at multiple spatial points. This enables high-resolution reconstruction of three-dimensional wind fields.

To meet a wide range of measurement needs, the Molas 3D supports various scanning modes, including:

• PPI (Plan Position Indicator): Performs horizontal sector scans or full 360° rotations, ideal for comprehensive wind field mapping across large areas.
• RHI (Range Height Indicator): Executes vertical elevation scans, well-suited for capturing vertical wind profiles and analyzing boundary layer structures.
• DBS (Doppler Beam Swinging): Utilizes multi-beam fixed-direction scanning, allowing precise retrieval of horizontal wind vectors and vertical velocity components.
• Program Scan: Offers user-defined custom scanning trajectories, providing maximum flexibility for specialized research applications.

The system boasts a maximum acquisition distance of 15 kilometers and a sight detection range extending up to 10 kilometers at 600 meters altitude. Vertically, measurements can reach as high as 4 kilometers. Users can configure distance resolutions at 15 m, 30 m, 75 m, or 120 m, with support for up to 300 distance layers. The line-of-sight wind speed measurement range covers -75 m/s to +75 m/s with an accuracy of 0.1 m/s. Furthermore, the scanning head enables a full 360° horizontal rotation combined with vertical tilting from -10° to 190°, achieving a pointing precision of ±0.005°, assuring reliable and repeatable data collection.

Designed for versatile usage, the Molas 3D is ideally suited for a variety of demanding applications:

• Offshore Wind Resource Assessment: Provides accurate wind mapping in marine environments where conventional meteorological masts are impractical or expensive to deploy.
• Complex Terrain Research: Enables detailed analysis of wind flows across mountains, hills, and valleys characterized by highly inhomogeneous wind patterns.
• Wind Turbine Wake Detection: Visualizes and examines wake deficits and turbulence downstream of turbines, aiding in the optimization of wind farm layouts and reducing fatigue loads.
• Airport Glide Path Wind Shear Warning: Delivers early warnings of dangerous wind shear conditions along aircraft approach paths, enhancing aviation safety.
• Urban Meteorological Observation: Captures dynamic wind field behavior within urban canyons, supporting city planning and pollution dispersion studies.
• High-Altitude Turbulence Detection: Monitors atmospheric turbulence at elevated altitudes, contributing to aviation safety and climate research efforts.

The Molas 3D is engineered for dependable operation under harsh environmental conditions. It operates within a temperature range from -40°C to +60°C and tolerates humidity levels between 0% and 95% RH (non-condensing). The system enclosure holds an IP65 rating, while internal components achieve IP66 protection standards. Data can be stored locally for durations ranging from 5 to 18 months in standard .csv file format. Communication is facilitated through 1000BASE-TX Ethernet or 4G remote access, with output interfaces including Profibus DP, Modbus TCP, and CAN options, enabling seamless integration with diverse control and data acquisition systems.

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