Profiles of vertical heat flux were obtained by subtracting the component of temperature change due to long‐wave radiation flux divergence from some observed temperature changes and integrating the resultant temperature change. the method of computing the radiative component was essentially one suggested by Funk (1961). the resultant fluxes of sensible heat showed significant height variations near the ground at night but almost no variation near the ground in the day. At night the coefficient of eddy conductivity increased with height up to about 50 metres and subsequently decreased. In the daytime the concept of thermal diffusion does not appear to adequately describe the sensible heat flux.
