Sight Wind Speed Accuracy 0.1 Meters Per Second Doppler Wind Lidar Operating

Product Description:

The Molas 3D is a cutting-edge three-dimensional scanning Doppler wind measurement lidar, designed on the fundamental principle of pulsed laser coherent Doppler frequency shift. By emitting pulsed laser beams and detecting the frequency changes in backscattered signals from atmospheric aerosols, this system accurately calculates the line-of-sight wind speed and direction at multiple spatial points. This capability enables the reconstruction of high-resolution, three-dimensional wind fields.

This lidar system offers a diverse range of scanning modes to meet various measurement needs:

• PPI (Plan Position Indicator): Enables horizontal sector or full 360° scanning, which is perfect for mapping wind fields across extensive areas.
• RHI (Range Height Indicator): Facilitates vertical elevation scanning, ideal for capturing vertical wind profiles and boundary layer structures.
• DBS (Doppler Beam Swinging): Employs multi-beam fixed-direction scanning to accurately retrieve horizontal wind vectors and vertical velocity components.
• Program Scan: Allows user-defined custom scanning trajectories, offering maximum flexibility tailored for specialized research projects.

The Molas 3D boasts impressive measurement capabilities, featuring a maximum acquisition range of 15 kilometers and an effective sight detection range of 10 kilometers at an altitude of 600 meters. Its vertical measurement extends up to 4 kilometers, with configurable distance resolutions of 15, 30, 75, or 120 meters, and support for up to 300 measurement layers. Wind speed detection spans from -75 m/s to +75 m/s, providing a high accuracy of 0.1 m/s. The scanning head can rotate 360° horizontally and tilt vertically between -10° and 190°, with a pointing precision of ±0.005°, ensuring consistent and reliable data collection.

Designed for a broad spectrum of challenging applications, the Molas 3D excels in:

• Offshore Wind Resource Assessment: Offers precise wind mapping over sea areas where conventional meteorological masts are impractical or expensive.
• Complex Terrain Research: Captures detailed wind flow characteristics over mountains, hills, and valleys where wind patterns are highly variable.
• Wind Turbine Wake Detection: Visualizes and analyzes wake deficits and turbulence downstream of turbines to optimize wind farm layouts and reduce mechanical stress.
• Airport Glide Path Wind Shear Warning: Provides early warnings of dangerous wind shear conditions along approach paths, enhancing aviation safety.
• Urban Meteorological Observation: Monitors wind field dynamics in urban environments, supporting city planning and pollution management.
• High-Altitude Turbulence Detection: Supports aviation and climate research by monitoring atmospheric turbulence at elevated altitudes.

The system is engineered for reliable operation under harsh environmental conditions. It operates within a temperature range of -40°C to +60°C and tolerates humidity levels from 0% to 95% relative humidity (non-condensing). The enclosure is rated IP65, while internal components comply with IP66 standards. Data storage capabilities range from 5 to 18 months using standard CSV format, with data transmission supported via 1000BASE-TX Ethernet or 4G remote access. Additionally, the Molas 3D includes multiple output interfaces such as Profibus DP, Modbus TCP, and CAN, which ensure seamless integration with a variety of control and data acquisition systems.

With its robust performance, versatile scanning modes, and wide-ranging applicability, the Molas 3D represents a premier solution for advanced wind measurement and atmospheric research. It empowers industries and researchers to make informed, data-driven decisions with confidence and precision.
