Sample Atmospheric Surface Layer Velocity and Temperature Measurements


Longitudinal Velocity (u)
Lateral Velocity (v)
Vertical Velocity (w)
Air Temperature (Tv)

The three velocity components (m/s) and temperature (K) measurements shown in adjacent figure were collected above a grass-covered forest clearing on 07/12/1995 at 5 m above the ground surface and at a sampling rate of 56 Hz. The ASCII files used to generate the time series displayed in the adjacent figure can be down-loaded. Details of the experiment can be found in:
