✦ Synopsis

Turbulence spectra and integral statistics measured in unstable conditions over a suburban surface are presented. The stability dependence of the integral statistics is shown to be consistent with surface layer scaling with adiabatic limits near those over much smoother surfaces. The spectra are computed over a wider range of non-dimensional frequency than previously reported for this type of surface, and show clearly the low-frequency roll-off The horizontal components show three distinct spectral regions as elucidated by . Due to large uncertainties in the spectral amplitudes, very little systematic dependence on the Monin-Obukhov stability parameter could be detected over a wide range of unstable conditions.
