Profiling lidar

For the profiling lidars, we plan:

- global study (throughout XPIA) comparing the WCv1 lidars to each other and to the WCv2 lidar (after it was deployed 12 March)
- global study (throughout XPIA) comparing the lidars to tower sonics for mean wind speed and direction
- global study (throughout XPIA) comparing the wind fluctuations from the lidars to TKE from the tower sonics
- case study of some interesting LLJs (0-6 UTC) such as 5 March, 16-17 March (odd NEly jet), 4 Apr, 6 Apr (2-6 UTC), 6-7 Apr (22-4 UTC), 10 Apr (0-6 UTC), 12 Apr (0-12 UTC), 14 Apr (0-8 UTC, very strong),  23 Apr (0-8 UTC, very strong, sswly), 24 Apr (0-6 UTC, pulsing LLJ, NWly)
