When wiki.ucar.edu was down I put misc entries here:
6-4-09 (twh) NOTE: I found (see below) that the 8m sonic on the profile tower appears to have occurred on 8-11
8/11:
New heights were 5.37m above ref4 level (which is 0.04m above ref3 level).
Thus, the new heights should be 5.37+1.65=7.02m and 8.02m. upwind was setup
this way.
These are close enough to the existing profile 7.08 and 8.05, that we're not planning
to move them.
