Using an online trajectory analysis tool NASA, ArcGIS, Satellite and EPA in situ data, we assess whether high pollution events in Texas are primarily sourced locally or remotely. We focus satellite data that exemplify high O3 and NO2 over Texas’s lower troposphere. Four day back trajectory analyses of all dates show that upper-, mid-, and lower-tropospheric air over Texas, containing high O3, is transported from the Gulf of Mexico, Southeast USA, Midwest USA, Northeast USA, the Atlantic Ocean, Pacific Ocean, Mexico, etc. Only day showed air at 1 km is sourced within Texas. Satellite data show O3 enhancements in the boundary layer and O3 and NO2 enhancements via tropospheric column profiles. These enhancements complement four-day trajectory analysis. This study provides a viable basis for more quantifiable and accurate information for developing effective air quality State Implementation Plans.

STEM Impact: (i) D. Bella was an NSF-LSAMP undergraduate research mentee with me at Medgar Evers College-CUNY; she received a B.S. in Environmental Science (and a Chemistry Minor) and is now a Ph.D. graduate student at University at Albany’s School of Public Health. (ii) J. Khaimova is an undergraduate Geology and Planetary Science B.S. major at Brooklyn College-CUNY. I have supported Jessica’s summer internship in summer 2013 as a CUNY Summer Research Fellow, where she is currently an NSF-REU research mentee at Pennsylvania State University’s Meteorology Department. (iii) J. Culpepper received his B.S. in Environmental Science from MEC-CUNY and will be a Ph.D. student, Fall 2014 at University of Iowa’s Civil and Environmental Engineering Department. (iv) S. Gentle was a high school researcher with me within ACS’s Project SEED Program for high school students. S. Gentle will start her undergraduate career Fall 2014 at Pennsylvania State University and seeks to attain a B.S. in Chemistry. (v). All parties, including high school and undergraduate researchers seek to attend medical/graduate school to pursue an M.D/Ph.D. in a STEM-discipline.
