During the Deepwater Horizon (DWH) oil spill, a wide range of
gas and aerosol species were measured from an aircraft around,
downwind, and away from the DWH site. Additional hydrocarbon
measurements were made from ships in the vicinity. Aerosol
particles of respirable sizes were on occasions a significant air quality
issue for populated areas along the Gulf Coast. Yields of organic
aerosol particles and emission factors for other atmospheric pollutants
were derived for the sources from the spill, recovery, and
cleanup efforts.
