摘要: Abstract Deposition velocities for O3 to grassland have been measured by the gradient method. Values range from 0.08 0.91 cms−1 and are shown be influenced most substantially changes in surface conditions. deposition is inhibited presence of snow or moisture at tends decrease as afternoon progresses. Vertical profiles temperature 100 m height indicative depletion dry a diminution concentration ground-level due inhibition vertical mixing aloft during periods atmospheric stability. Dry fluxes adequate account diurnal variation observed rural areas summer anticyclonic
