Description:
Sensible heat flux measurements were made in an agricultural setting near Champaign, Illinois by using doppler sodar, eddy correlations and profile methods during convective conditions during an experimental study called VOICE, (Vertical Observations Involving Convective Exchange). This paper presents details of the analyses which compares the heat flux measurements by these three techniques. The sodar data represents volume average estimates while the other two standard techniques are point time measurements. The results for these three methods are comparable but sodar estimates show wide variability during the midmorning time period compared to the other techniques.
