In situ temperature and velocity spectra of atmospheric turbulence obtained from sensors suspended below a stable kite platform yield accurate high-resolution measurements of the temperature structure constant and the energy dissipation rate. The statistical description of the variability of these small scale turbulence metrics below the nose of a nocturnal low level jet during CASES-99 are presented. These include the probability density function and the spatial spectrum from multiple sensor packages as well as comparison with redictions of turbulence theory.
