During the reporting period, experimental data collected in June 2010 were analyzed, and a more sophisticated experiment was conducted in June 2011. The analysis of the 2010 data set confirmed that the optical retrievals of (1) temporal fluctuations of path-averaged, vertical temperature gradient fluctuations, (2) path averages of the transverse wind velocity, and (3) path averages of the temperature structure parameter agreed well with the sonic measurements down to time scales of 1 minute or even less. 收起
