WINDCUBEv2 introduction The WINDCUBEv2 is a Lidar (Light Detection And Ranging) used for wind profile measurement up to 200m. The Lidar sends infrared laser pulses into the atmosphere. Four beams are sent successively in four cardinal directions along a 28°scanning cone angle. Laser pulses are backscattered by aerosol particles in the air (dust, water droplets, aerosol, etc.), that move at wind speed. The collected backscattered light allows for the calculation of wind speed and direction using Doppler induced laser wavelength shift. Up to 10 different range gates can simultaneously be measured using the laser pulse time of flight allowing to measure the wind speed at
10 different heights. The backscattered light is converted into an electronic signal and digitized. A dedicated signal processing algorithm computes wind vector components from four consecutive line of sight measurements. Leosphere Windsoft software controls the hardware and performs the processing. The user interacts with the WINDCUBEv2 (measurement configuration and real-time monitoring) through a graphical user interface, Windweb. Windweb can be displayed on any web-browser. Real time and statistical wind data are stored on WINDCUBEv2’s solid-state hard disk drive. The user downloads accumulated data files

1. IDENTIFY LOCATION • Before installing your WINDCUBEv2, determine its future location and ensure that:
Wind 28°
Fig. 6 - No obstacle in prevailing wind direction The system is located away from any obstacles in all wind directions of interest (Fig. 6).
28°
Fig. 7 - No obstacle in scanning cone
Obstacles do not interfere with any of the four 28° laser beams (Fig. 7).

Ackowledgements 2. PREPARE AND SECURE LOCATION
Difference of altitude
Fixing ring against theft
Fig. 8 – Put on flat ground or hard material. Possible tilt up to 15° In case the ground is soft and/or wet at the site location, it is highly recommended to install the WINDCUBEv2 on a wood palette (or any hard material) to make sure that the system level remains stable over time. A proper and consistent level is vital to maintain in order to keep the same altitude on both sides of the scanning cone and record accurate data (Fig. 8).
Fig. 9 – Chain WINDCUBEv2 to anchor RECOMMENDATION To prevent theft, chain WINDCUBEv2 to one or more ground anchors. Hook a heavy duty chain (not included) through WINDCUBEv2 ring (Fig. 9). The anchor should be located below the system so it is less visible to the public. Plan to install hook on chosen spot

3. INSTALLATION • Unpack system and its elements
Shipping case must be placed in a dry environment.
• Install WINDCUBEv2 in the predetermined location. • Adjust the levelling of WINDCUBEv2: use adjustable feet to center the bubble in the level located atop the system (Fig. 10). NOTE: Fine level adjustments are performed through Windweb interface. This step is described later (Fig.23).

What is CNR?
CNR = Career to Noise Ratio This value depends on the concentration of aerosols in the atmosphere that backscatter laser light. High atmospheric backscatter coefficient leads to high CNR. CNR level depends on weather conditions. .

• The four curves should have approximately the same signal level. If one (or more) curves are more than 3dB below the other, it means that an obstacle blocks one (or more) beam. • Rotate WINDCUBEv2 in order to have all CNR curves superimposed (within a 3dB tolerance margin) and as shown in the good print screen above.
