AB: The Port of Houston is made up of the Houston Ship Channel and Galveston Bay. Together these comprise a 25- mile long complex of diversified public and private facilities, including a petrochemical complex that is among the largest in the world. The Houston Ship Channel is a major source of industrial pollution, emitting sulfur dioxide (SO₂), nitrogen oxides (NO_x), carbon monoxide (CO), carbon dioxide (CO₂), and volatile organic compounds (VOC). Unlike a single large power plant, the Houston Ship Channel consists of numerous sources that can be difficult to quantify in inventories. In order to evaluate and predict air quality in the Houston area, it is important to understand the magnitude and variability of sources in the Houston Ship Channel, and how these sources are evolving over time. We examine fluxes of SO₂, NO_x, and CO₂ from the Houston Ship Channel observed onboard the NOAA WP-3 during September - October 2006. We report the magnitude of these sources, and compare these results to aircraft measurements from 2000 to identify trends.
