Turbulent transport near the ground as determined from measurements of the ozone flux and the ozone gradient

Simultaneous measurements of the vertical fluxes of ozone and heat were made near Albuquerque, New Mexico, in 1968, together with measurements of the vertical profiles of ozone and temperature in the first 16 meters above the surface. The eddy flux of ozone was determined by a new method using the decay of ozone in a box with open bottom, placed on the ground. The eddy flux of heat was determined as the difference between the net radiative flux and the soil heat flux. The vertical distributions of ozone, temperature, and wind were measured with sensors mounted on a platform that was raised and lowered electrically along a 16-meter tower. The profiles and the flux values are used to compute coefficients of eddy diffusivity of ozone and heat. The results show that measurements of the ozone flux and of the ozone gradient can be used for determinations of the eddy transport of atmospheric properties in low-wind situations, whenever measurements of temperature or wind profiles, and of the related fluxes, are not practical.
