Measurements of Aerosol Size and Chemical Composition by a Compact Time of Flight Aerosol Mass Spectrometer (C-ToF-AMS) Aboard NOAA WP-3D Aircraft during TexAQS- 2006
Abstract
In the summer of 2006, NOAA WP-3D aircraft will conduct research flights in eastern Texas as part of the Texas Air Quality Study (TexAQS)/Ozone 2006 campaign. With the extensive suit of instruments aboard the aircraft that measure concentration and properties of gas phase and particle phase pollutants, research flights will be planned to characterize daytime/nighttime urban pollution and to study the influence of the regions chemical/petrochemical industries on air pollution in eastern Texas. In this presentation, preliminary data on size dependant chemical composition of non-refractory sub-micron aerosols (ie. organics, sulfate, nitrate, and ammonium) measured by a Compact Time of Flight Aerosol Mass Spectrometer (C-ToF-AMS) will be presented. C-ToF-AMS data will be examined for correlations (or lack thereof) between aerosols' size and chemical composition and aerosol precursors measured aboard the aircraft in order to understand the mechanisms that lead to particle production and growth in the region as the pollution plumes are advected away from the sources.
