AN EVALUATION OF HEAT FLOW TRANSDUCERS AS A MEANS OF DETERMINING SOIL HEAT FLOW,
Abstract
From data the author obtained on the Dallas Tower Program, an investigation is made of the responses of several newly-designed heat flow transducers in the soil under varying meteoro logical conditions. The Fourier heat conduction equation is used as a standard in evaluating the transducers' ability to represent surface soil heat flow. The results show that acceptable performance of the plates in the measurement of heat flow is possible although in general should not be expected without thorough testing, and even then there are restrictive considerations, primarily in depth of placement. This holds for averaging periods as short as 15 min, although better results are obtained with longer time intervals. The results also show that the new transducers are much more accurate than the older standard types, and that c-stent varia tions in response are not introduced by varia tions in soil moisture.
