Estimating Primary and Secondary Production of Formaldehyde in Houston Based on Aircraft and Ground-Based Measurements During SHARP
Room 342 (New Orleans Convention Center )

As part of the 2009 SHARP (Study of Houston Atmospheric Radical Precursors ) project, aircraft-based and ground-based measurements of SO2, CH2O, CO, NOx NOy and alkenes were made of the Houston-Galveston urban area, the Houston Ship Channel (HSC), and the Mt Belvieu area. Sources of ambient mixing ratios of formaldehyde include biogenic, mobile or industrial sources through either primary or secondary formation. This work investigates these sources by utilizing CH2O/CO, CH2O/NOy, SO2/CH2O ratios and other methods to categorize these sources.
