Sight Wind Speed Accuracy 0.1mps Doppler Wind Lidar with 10km Detection Distance under 600m Height and Temperature Range Minus 40 to Plus 70 Celsius

The Molas 3D is an advanced three-dimensional scanning Doppler wind lidar, meticulously designed based on the principle of pulsed laser coherent Doppler frequency shift technology. By emitting pulsed laser beams and analyzing the frequency shifts of the backscattered signals reflected from atmospheric aerosols, this system accurately determines the line-of-sight wind speed and direction at various spatial points. This capability enables high-resolution reconstruction of three-dimensional wind fields.

To meet a wide range of measurement needs, the Molas 3D offers multiple versatile scanning modes:

• PPI (Plan Position Indicator): Enables horizontal sector or a full 360° sweep, perfect for mapping wind patterns over large areas.
• RHI (Range Height Indicator): Conducts vertical elevation scans, ideal for capturing vertical wind profiles and boundary layer structures.
• DBS (Doppler Beam Swinging): Utilizes multi-beam fixed-direction scanning to precisely retrieve horizontal wind vectors and vertical velocities.
• Program Scan: Allows users to define custom scanning paths, providing flexibility tailored to specialized research requirements.

The system boasts a maximum acquisition range of 15 kilometers and a sight detection capability extending up to 10 kilometers at 600 meters altitude. Vertically, it can measure up to 4 kilometers with configurable distance resolutions of 15 m, 30 m, 75 m, or 120 m, supporting up to 300 discrete range layers. Its wind speed measurement along the line of sight ranges from -75 m/s to +75 m/s with a fine accuracy of 0.1 m/s. The scanning head offers 360° horizontal rotation and vertical tilt ranging from -10° to 190°, with a pointing precision within ±0.005°, ensuring highly reliable and repeatable data acquisition.

The Molas 3D is specifically engineered to serve multiple challenging applications:

• Offshore Wind Resource Assessment: Provides precise wind mapping over marine environments where traditional meteorological masts cannot be practically deployed or are cost-prohibitive.
• Complex Terrain Research: Effectively characterizes wind flow in mountainous, hilly, and valley regions where wind patterns exhibit significant heterogeneity.
• Wind Turbine Wake Detection: Enables visualization and analysis of turbine wake deficits and turbulence, assisting in optimizing wind farm layouts and reducing structural fatigue.
• Airport Glide Path Wind Shear Warning: Offers early detection and alerts for hazardous wind shear conditions along aircraft approach paths, enhancing aviation safety.
• Urban Meteorological Observation: Captures wind dynamics within urban canyon environments, supporting city planning and pollution dispersion analysis.
• High-Altitude Turbulence Detection: Monitors atmospheric turbulence at elevated altitudes, aiding aviation operations and climate-related research.

Designed for robust performance in harsh environments, the Molas 3D operates reliably across a temperature range from -40°C to +60°C and tolerates relative humidity levels between 0% and 95% (non-condensing). The device’s enclosure is rated IP65, while the internal components meet the stricter IP66 standard. Data storage is available locally for periods between 5 and 18 months in standard .csv file format. For data transmission, the system supports 1000BASE-TX Ethernet and remote access via 4G networks. Additionally, it includes multiple output interfaces such as Profibus DP, Modbus TCP, and CAN protocols, ensuring easy integration with diverse control and data acquisition systems.
