Abstract The turbulent fluxes of ozone and latent and sensible heat are computed from fast-response measurements made aboard a NOAA aircraft over downtown Philadelphia and the surrounding suburbs during the afternoon and evening of 22 August 1979. The normalized variances and spectra of vertical velocity, temperature, and ozone show little change with height or location in the urban center and northwest suburbs during the afternoon. Data from a cloud penetration by the aircraft is used to estimate a mean updraft velocity of 4 m/s and an updraft area of approximately 1 sq km. The flux of ozone due to the mean motion in the updraft is two orders of magnitude larger than the turbulent eddy fluxes within the cloud.
