During 2006 NOAA Texas Air Quality Study (TexAQS II) field
mission members of the Real-time Air Quality Modeling System (RAQMS)
team, in collaboration with representatives from the NOAA P3 and NASA
HSRL, AIRS, CALIPSO, OMI, and TES instrument teams, conducted a field
study involving synthesis of near-real-time satellite, airborne and
surface measurements, and RAQMS chemical/aerosol analyses to
investigate regional influences on Houston and Dallas Air Quality.
Results show that enhanced background O3 production was present 16% of
days during the study in Houston and Dallas Fort Worth (DFW), and
preceded 3 out of 6 Houston periods and 4 out of 6 DFW periods with
elevated O3. Case studies linking Houston local air quality to remote
satellite observations during TEXAQS illustrate the influence of remote
emissions from the SE US and Pacific NW on Houston air quality and
demonstrates the importance of integrating of satellite, aircraft, and
surface measurements of aerosol and trace gases in conjunction with
advanced modeling techniques for characterizing the impact of emissions
from remote sources on local air quality.
