Description:

Next generation air measurements (NGAM) is an EPA term for the advancing field of air pollutant sensor technologies, data integration concepts, and geospatial modeling strategies. Ranging from personal sensors to satellite remote sensing, NGAM systems may provide revolutionary new capability in exposure and air quality science. One aspect enabled by NGAM is improved understanding of fugitive and area sources of air pollution and greenhouses gases. Whereas the knowledge base for emissions from point sources (stacks) and mobiles sources (tailpipes) is relatively mature, non-point such as landfills, waste water, and agricultural operations, and fugitive sources in industrial facilities and energy production is in less developed. The reason for this lies in the complexity of these sources that can be of significant spatial extent or distributed over large areas with uncertain emission locations. Emissions can be temporally variable and profoundly affected by environmental factors and operational conditions. The stochastic and site-specific nature of fugitive and area sources make them difficult to both measure and model. This talk provides a brief overview of some NGAM concepts in the in fugitive and area source space.
