Abstract: Utilizing the concepts of localized near-field diffusion, a modeling system was developed to estimate isoprene emissions from foliage of a mixed deciduous forest. The model determined radiation disposition and foliage ...

Abstract: The primary objective of this study was to understand the environmental and seasonal controls over isoprene emissions from a boreal forest ecosystem whose isoprene source came from trees of the same species and age. A ...

Abstract: Above-canopy sampling of trace gases to determine volatile organic compound (VOC) emissions should be interpreted in terms of footprint considerations. This can be accomplished by defining the upwind canopy areas effectively ...

Abstract: During the wet season in the southwestern Amazon region, daytime water transport out of the atmospheric mixed layer into the deeper atmosphere is shown to depend upon cloud amounts and types and synoptic-scale velocity ...

Abstract: Nonmethane hydrocarbons are ubiquitous trace atmospheric constituents yet they control the oxidation capacity of the atmosphere. Both anthropogenic and biogenic processes contribute to the release of hydrocarbons to the ...
