Biogenic hydrocarbon emission estimates for North Central Texas

Biogenic hydrocarbon emissions were estimated for a 37 county region in North Central Texas. The estimates were based on several sources of land use/land cover data that were combined using geographical information systems. Field studies were performed to collect species and tree diameter distribution data. These data were used to estimate biomass densities and species distributions for each of the land use/land cover classifications. VOC emissions estimates for the domain were produced using the new land use/land cover data and a biogenic emissions model. These emissions were more spatially resolved and a factor of 2 greater in magnitude than those calculated based on the biogenic emissions landuse database (BELD) commonly used in biogenic emissions models.
