Abstract
This work presents measurements of sulfur dioxide (SO2) emission fluxes from point sources using airborne near-ultraviolet (UV) spectroscopy. A Czerny-Turner spectrograph has been optimized to measure SO2 and the oxygen collision complex (O4) in the wavelength region of 286-408 nm from an aircraft platform. The spectrograph was deployed aboard the NOAA WP-3D Orion aircraft during the New England Air Quality Study during the summer of 2004. The spectrograph has zenith and nadir field of views, allowing for measurements of pollution plumes when the aircraft is in or above the planetary boundary layer. The near-UV spectra are analyzed using the differential optical absorption spectroscopy (DOAS..
