FLUXES AND RATES OF OZONE DRY DEPOSITION IN THE FOREST ENVIRONMENT NEAR LAKE BAIKAL

摘要

The results of measurements of surface ozone concentration in a forest near the coastal zone of Lake Baikal were analyzed. Using a micrometeorological models the characteristics of gas exchange processes (fluxes and rates of dry deposition) between the atmosphere and forest vegetation are studied. A new modified micrometeorological gradient method has been developed and used to quantify the dry deposition of ozone over the forest canopy using concentration gradients at levels above and below the top of the forest canopy. Based on the approved calculation method and experimental data the quantitative estimates of flows and rates of dry ozone deposition in the forest environment in Baikal region were obtained.
