Texas Photochemical Modeling Results—Interactive Map

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

Hourly pollutant concentrations from the TCEQ’s 2006 episodic photochemical modeling are shown below as a shaded overlay on an interactive Google Map. Only results from the 4 km modeling domain are displayed. Other features include:

  • A control menu (right side of map) to alter and turn specific features on or off.
  • Date and time controls above the map in Local Standard Time (LST).
  • Surface pollutant observations from the Texas Air Monitoring network, represented with circles for the same time period.
  • A color scale for the modeled and observed pollutant concentrations.
  • Wind speed and direction observations using meteorological wind barbs.
  • Hover over the markers to view observed concentration or wind speed and direction values.

Learn about the model configuration.

This modeling replicates a period in 2006 and is not real time. Pollutant concentrations are shown, not emissions.
