    abstract = "The surface heat flux (Q(O)) and the friction velocity (u*) are
important parameters of the Atmospheric Boundary Layer (ABL). Vertical
velocity variance (sigma(w)2) profiles have been used to estimate the
parameters Q(O) and u* from             Acoustic Sounder (AS) data
according to the similarity theory. A comparison was made using data
from a 12 m high mast equipped with humidity, and fast responding wind
and temperature sensors and a high resolution monostatic AS. The
comparison confirms the ability of the sigma(w)2 profile method to
provide, even in a noisy environment (inhabitant area), estimates of
these parameters with reasonable accuracy and on a continuous basis. The
requirements for the method to be applied is that convective conditions
or a minimum mechanical mixing exist and the level of acoustic noise is
not too high."
