The following graphs show an example of wind velocity (left) and signal strength (right) of wind measurements with 13 ° elevation (5000 shots at 10 kHz, averaged over 500 ms) over a time of 45 hours (x-axis).
The color scale in the left graph shows wind velocities of -2,7 m/s (blue) to 8 m/s (red). Positive velocities describe wind directions towards the system. The range (y-axis) of the system of these measurements is 2-3 km. Cloud structures with strong backscatter can be identified in a range of up to 8-10 km.
The visibility according to the DWD-Wetterstation in Göttingen during this measurement was 10 to 59 km.
The following graphs show wind velocities (left) and signal strength (right) of a wind measurement for 75 min (top) and 10 min (bottom) at an elevation of 57° with 5000 shots at 10 kHz averaged over 50 ms. The graphs for wind velocities show wind turbulences in up to 1 km distance to the measurement system.
The visibility according to the DWD-Wetterstation in Göttingen during this measurement was 26 km (top) and 13 km (bottom).
