RISDeducing Ground-to-Air Emissions from Observed Trace Gas Concentrations: A Field Trial with Wind Disturbance
Publisher: American Meteorological Society
Abstract: Inverse-dispersion techniques allow inference of a gas emission rate Q from measured air concentration. In ?ideal surface layer problems,? where Monin?Obukhov similarity theory (MOST) describes the winds transporting the ...
Deducing Ground-to-Air Emissions from Observed Trace Gas Concentrations: A Field Trial
Publisher: American Meteorological Society
Abstract: The gas emission rate Q from an artificial 36-m2 surface area source was inferred from line-average concentration CL measured by an open-path laser situated up to 100 m downwind. Using a backward Lagrangian stochastic (bLS) ...
Ammonia Emissions from Anaerobic Swine Lagoons: Model Development
Publisher: American Meteorological Society
Abstract: Concentrated animal production may represent a significant source for ammonia emissions to the environment. Most concentrated animal production systems use anaerobic or liquid/slurry systems for wasteholding; thus, it is ...
