Texas Photochemical Modeling Results—Interactive Time-Series Plot

Interactive chart comparing results of the TCEQ’s air quality modeling and surface observations.

This interactive chart shows time-series plots of pollutant concentrations from the TCEQ's 2012 photochemical modeling comparing modeled values with available surface observations at locations of air quality monitoring sites in Texas. The observed data are shown as red dots; modeled data a solid blue line; and modeled 3×3-cell minimum and maximum range a light-blue shaded area.

If you have any questions regarding this interactive chart, please send an email to amda@tceq.texas.gov with the subject "Texas Photochemical Modeling Results - Interactive Time-Series Plot".
