This paper reports the first power spectra of ozone (O 3 ) in the surface layer for which the data quality approaches that of high‐quality spectra of meteorological properties. These results are employed in a surface layer scalar similarity study involving temperature, moisture, and O 3 measurements over cotton. All data were obtained during the California Ozone Deposition Experiment, in the San Joaquin Valley of California, during July and August, 1991. A detailed comparison of nondimensional scalar power spectra during unstable conditions showed that the three scalars behaved similarly, thereby providing the first completely general test of scalar similarity theory.
