The trace gases released or influenced by plants play a key role in atmospheric processes. In the troposphere, methane and carbon monoxide are key species that react with the hydroxyl radical (OH), an effective atmospheric detergent. Carbon monoxide is formed by the oxidation of the biogenic hydrocarbons discussed previously. In the presence of NO, the oxidation of CO, CH{sub 4} and NMHC can lead to the formation of ozone, a tropospheric pollutant. In the stratosphere, methane is an important source of water vapor. Volatile sulfur compounds released by plants may be an important source of cloud condensation nuclei. Collectively, these compounds may directly regulate the earth`s climate because they are radiatively active and influence the radiation balance at the earth`s surface or indirectly regulate the earth`s climate because they influence the concentration of radiatively active gases. The focus of the workshop was on naturally occurring gas fluxes. It is sometimes claimed that the gas fluxes from plants pollute the atmosphere. Our focus was on the natural chemistry occurring at the biosphere-atmosphere interface. Individual reports are processed separately for the data bases.
