Microscale temperature fluctuations were measured at 2 m above a grassy surface. The temperature-derivative spectrum was in general agreement with earlier results but the bump at nondimensional wavenumbers higher than 0.02 was not as pronounced as has been observed. The Obukhov-Corrsin constant for

Production, transport and dissipation terms in the temperature variance equation have been measured in the atmospheric surface layer. The transport term is, within the experimental uncertainty, negligible. The dissipation term, determined by assuming local isotropy, is approximately equal to product
Production, transport and dissipation terms in the mean cube temperature equation have been evaluated from measurements in the atmospheric surface layer under moderately unstable conditions. The transpart term, calcuIated by making use of the quasi-Gaussian approximation, is, on average, comparable
## Abstract This paper describes a singleβbeam infrared fluctuation hygrometer, operating in the 2.7 ΞΌm water vapour band. By restricting attention to frequencies making up the atmospheric eddy spectrum, a calibration equation for fluctuations is obtained which is independent of moderately stable i
