✦ Synopsis

By non-dimensionalizing a trajectory-simulation (TS) model of turbulent dispersion, it is shown that the dimensionless concentrationz,cu./kQ (cu./kQ)due to a continuous line (area) source ofstrength Q in the atmospheric surface layer depends only on z/z,, x/zc, z,,/L and z,/z,, where z, is the source height. The TS model is used to tabulate concentration profiles due to ground-level line and area sources. Concentration profiles generated by the TS model for elevated sources are shown to be inconsistent with the Reciprocal Theorems of Smith (1957) and it is suggested that this is because the flux-mean gradient closure scheme inherent in the Reciprocal Theorem is invalid for an elevated source.

## Abstract Spectra and cospectra of turbulence in the constant‐flux surface layer of the atmosphere are studied with measurements made by rapid response propeller anemometers and a bead thermistor. The results are described in comparison with those obtained at other sites.

Velocity and temperature derivatives were obtained at a height of 4 m in the atmospheric surface layer above land. With the assumption of local isotropy, these measurements are used to obtain some statistics of the turbulent energy and scalar dissipation fields. These statistics include the variance
