Description

  • Content Description: The emission of NO from microbial processes in soils can contribute signif icantly to levels of NO{sub x} (NO + NO{sub 2}) in the planetary boundary layer and can lead to modifications of O{sub 3} concentrations there. Accordingly, the rates of NO emission should be simulated in atmospheric chemistry models used to investigate methods of reducing tropospheric concentrations of O{sub 3}. Developing good simulations of the rates is complicated by the large seasonal and spatial variability of NO emissions from soils. The availability of efficient methods of surveying NO emissions would result in more complete information for evaluating the model outputs. In addition, the atmospheric chemistry models need to take into account the rapid conversion of NO to NO{sub 2} in the lower atmosphere because this rapid conversion permits some of the NO{sub 2} to be removed by dry deposition before it mixes into the atmospheric boundary layer above the surface layer. Such small-scale processes usually must be parameterized rather than explicitly simulated in regional- or large-scale atmospheric numerical models used to construct tropospheric budgets of NOx. Here, preliminary results are described from experimental efforts (1) to evaluate methods of estimating NO emissions from soils and (2) to gather information that could lead to parameterization of the rapid conversion of NO to NO{sub 2} in the lowest few meters of the atmosphere.
