Performed air dispersion modeling to assess the air quality impacts from a variety of sources: drift from aerial spraying, wind erosion from piles of fly ash, fugitive emission of asbestos from an industrial facility, accidental leaks of chemicals from pipes or other structures , fertilizer decomposition following the explosion in a warehouse, active aeration of pesticide fumigation chambers.
Completed a modeling study of a hypothetical oil spill in the Red Sea which included VOC evaporation from the oil surfacing on the sea, as well as other air emissions associated with the recovery and remediation operations. This included smoke plumes from in-situ burning, emissions from response vessels in the vicinity of the spill, oil and gas flares, and emissions of the secondary organic aerosols which form as a result of reaction of less volatile hydrocarbons with the atmosphere.
Analyzed meteorological data and helped provide expert opinions on meteorological conditions for a number of clients’ needs, including the meteorological impacts on solar panels, batteries in cars, LNG facilities, and siting of air quality monitoring instruments.
