The wind direction sensor (WD) is mounted on the lower (shorter) 'leg' of the arm.
The wind speed sensor (u) and lightning rod are mounted on the upper (longer) 'leg'.
2. The 2-sided mounting arm is fitted to the middle section of the mast at about 2.7 m.
The upper temperature sensor (T+) is mounted on the longer side of the arm.
The NR Lite2 net radiometer (Q* or R
The bubble level and the anti-bird stick must be facing upwards.
The net radiometer must be pointing towards the equator to avoid shadows from the mast.
3. The 1-sided mounting arm is fitted to the lower section of the mast at a height of about 0.5 m.
The lower temperature sensor (T-) is mounted on the arm.
The sensor must be oriented vertically below the upper temperature sensor.
) is mounted on the shorter side of the arm.
