Product Description:
Molas 3D: Advanced 3D Doppler Wind Measurement Lidar
The Molas 3D is a cutting-edge three-dimensional scanning Doppler wind lidar, developed based on the pulsed laser coherent Doppler frequency shift principle.
It operates by emitting pulsed laser beams and detecting frequency shifts in the backscattered signals reflected from atmospheric aerosols.
Using this data, the system precisely computes the line-of-sight wind speed and direction at multiple spatial points,
enabling high-resolution reconstruction of the three-dimensional wind field.
This state-of-the-art lidar supports a variety of scanning modes tailored to different measurement needs:
-
PPI (Plan Position Indicator):
Performs horizontal sector scans or full 360° rotations, ideal for mapping wind fields across large areas.
-
RHI (Range Height Indicator):
Conducts vertical elevation scans suited for capturing vertical wind profiles and boundary layer structures.
-
DBS (Doppler Beam Swinging):
Uses multiple fixed-direction beams to accurately retrieve horizontal wind vectors and vertical velocity components.
-
Program Scan:
Allows user-defined custom scanning paths, providing maximum flexibility for specialized research applications.
The Molas 3D achieves an impressive maximum acquisition range of up to 15 kilometers, with a sight detection range reaching 10 kilometers at an altitude of 600 meters.
Vertically, it can measure up to 4 kilometers in height, featuring configurable distance resolutions of 15, 30, 75, or 120 meters and supporting up to 300 discrete distance layers.
The wind speed measured along the line-of-sight ranges from -75 m/s to +75 m/s, with an accuracy of 0.1 m/s.
The scanning head is capable of a full 360° horizontal rotation combined with a vertical tilt spanning from -10° to 190°, maintaining a pointing accuracy within ±0.005°, ensuring highly reliable and repeatable data.
Designed to cater to a wide spectrum of demanding applications, the Molas 3D is employed in:
-
Offshore Wind Resource Assessment:
Precisely mapping wind conditions over marine environments where conventional meteorological masts are impractical or prohibitively expensive.
-
Complex Terrain Studies:
Analyzing wind flow over mountainous, hilly, and valley regions with highly variable wind patterns.
-
Wind Turbine Wake Detection:
Visualizing and analyzing wake deficits and turbulence downstream of turbines to optimize wind farm layouts and reduce mechanical fatigue.
-
Airport Glide Path Wind Shear Warning:
Providing early alerts of hazardous wind shear along approach corridors to enhance aviation safety.
-
Urban Meteorological Observation:
Monitoring wind field dynamics within urban canyons to support city planning and pollution dispersion studies.
-
High-Altitude Turbulence Detection:
Tracking atmospheric turbulence at elevated layers for aviation safety and climate research purposes.
Built to operate reliably in harsh environmental conditions, the Molas 3D can function within a temperature range of -40°C to +60°C,
tolerates humidity from 0% to 95% RH (non-condensing), and features an IP65-rated housing with internal components compliant with IP66 standards.
It offers local data storage capacity ranging from 5 to 18 months in standard .csv format.
Data transmission options include high-speed 1000BASE-TX Ethernet and remote access via 4G connectivity.
Output interfaces such as Profibus DP, Modbus TCP, and CAN facilitate seamless integration with diverse control and data acquisition systems.
Combining robust performance, versatile scanning capabilities, and extensive application flexibility, the Molas 3D is a premier solution for advanced wind measurement and atmospheric research.
It empowers professionals across industries to make informed, data-driven decisions with confidence and precision.
