| Zusammenfassung |
| Houston, Texas has long been an urban area plagued with high levels of surface ozone,
particularly in spring and late summer. The combination of a large commuter population and
one of the largest concentrations of petrochemical plants in the world results in abundant and
nearly co-located sources of NOx and hydrocarbons. The location of Houston on the
South Coast of the United States in a subtropical climate results in meteorological
conditions that favor ozone production. Using MOZAIC (1994 - 2004), ozonesonde
(2000, 2004 - 2010), and TES (2005 - 2010) data, we examine the evolution of
ozone profiles over Houston during a period in which various strategies have been
implemented to alleviate the ozone pollution problem. Using meteorological data
from associated soundings and analyses, we identify and evaluate influences on the
ozone profiles from natural and anthropogenic sources, as well as local and remote
sources. We further investigate how these various influences have changed with time. |
