ABSTRACT: Spatial and temporal heterogeneity in pollutant concentrations exists at
the intra-urban level. In this research work, the concentrations of various
pollutants and meteorological parameters are characterized between various
central ambient monitoring sites at Houston, TX, and the Rio Grande Valley
Regions of South Texas. Meteorological (temperature, relative humidity, wind
speed and direction) and pollutant (O3, SO2, CO, NO2, and various PM species) concentrations were
downloaded from the appropriate Texas Commission on Environmental Quality
(TCEQ) Central Ambient Monitoring Station (CAMS) sites for the year 2016.
Correlation Analyses and Coefficient of Divergence (COD) analyses suggest that
statistically significant differences occur between the various TCEQ CAMS sites
in the Houston Region. Findings from this study will help the various
stakeholders involved in assessing the overall air pollutants exposure burden
for the local populations.
