Daily summary plots of sonic anemometer means and cross
products. Three instruments are shown on each day, coded Red, Green and
Blue, corresponding to 4m, 16m and 32m nominal heights. Two styles of
plot are presented:
Means: which show time series of speed, direction
and Temperature; mean w, pre-tilt corrected w/s, u*; kU/u*, Pr,
de-spike ratio
