The initial bearing for our lidar was 230 deg, which was measured at the beginning of the experiment. Today (20170615), we remeasured and the bearing was 234deg. This agrees more with the coordinates above, so a coordinate rotation on the data may be necessary to correct wind speeds and directions on the VAD profiles.
For the lidar comparison, we were instructed to aim 1m above the 100m sonic on tower 25 (trSE_09). These are the coordinates:
Easting: 34152.59m
Northing: 4844.49m
Height: 403.75m
Using the all these values, the az and elev should be 227.96 and 23.34, respectively. Due to the wrong heading, we used 132.5 and 23.5 after some guessing and checking.
