The influence of rainstorm on soil respiration of a mixed forest in southern New England, USA was investigated with eddy covariance, rain simulation and laboratory incubation. Soil respiration is shown to respond rapidly and instantaneously to the onset of rain and return to the prerain rate shortly after the rain stops. The pulse-like flux, most… More

In this paper, a model is presented for scalar advection inside canopies. A key result is an advection/diffusion equation that captures the persistence effect of the diffusion plume from elevated sources through a near-field modifier. The model is applicable to various source configurations including line source, plane and canopy sources with finite fetch, and horizontally… More
