โœฆ Synopsis


From measurements in the atmospheric surface layer over a paddy field, the Kolmogorov constants for CO, and longitudinal wind velocity were obtained. In this study, the nondimensional dissipation rate & = (1-16~,)-'/2forC0,varianceand~~= (l-16i,)-'I"-i, for turbulent energy were used, assuming the equality of the local production term and the local dissipation term, and neglecting the divergence flux term in the budget equation. The value of the constant for CO, was consistent with recent determinations for temperature and humidity. The constant for longitudinal wind velocity showed good agreement with other recent observations.

Turbulent kinetic energy and its vertical flux were measured at two heights over a paddy field. The vertical transport of turbulent kinetic energy was always downward right above the paddy field and was frequently downward at higher levels within a few metres above the crop. Contributions to the dow
