Nitrogen (N) is the primary limiting nutrient for forest production. Therefore, understanding how environmental factors affect N transformation rates is essential for the provision of sustainable ecosystem services. Because these factors are interlin

Wind-tunnel experiments were conducted to investigate passive scalar diffusion behaviour in and above urban-like roughness under various thermal stratification conditions. Staggered arrays of rectangular blocks with aspect ratios of 0.96 or 1.92 were

Air velocity and temperature fields in urban street canyons depend mainly on the wind velocity at the rooftop level, the exposure of heated surfaces, and the canyon's aspect ratio (ratio of building height to street width). However, available experim

This paper proposes an atmospheric diffusion model for traffic-related emission in urban areas within a few hundred meters from relevant roads. The model adopts the mass-conservation (MC) principle for the velocity calculation and the advection-diffu

By a reduced-scale model in a wind tunnel, we investigate the dispersion behavior of exhaust gas from automobiles. Two types of vehicles are considered, a passenger car and a small-size truck. Tracer gas experiments show that the exhaust gas dispersi
