General Air Pollution and Meteorological Data
Air Quality and Meteorology
Hourly Air Pollution Data by Day, Month, or Year
Search for air quality data collected on a specific day, during a particular month, or a definite year and at a specific TCEQ air monitoring site.
Data Collected by Automated Gas Chromatographs (AutoGCs)
Links to air toxics data collected by our AutoGCs, a description of why this data is collected and how it is used, and monitoring network and program contact information.
Historical Pollutant and Weather Data
Air pollution and meteorological data from the TCEQ, local Texas monitoring networks, and the EPA, since 1972.
Web Camera Images of West Texas
Images showing current visibility, air quality, and meteorological information about the Big Bend, MacDonald Observatory, Guadalupe Mountains National Park, and El Paso.
Real-Time Winds Aloft
Current measurements of winds in the lower atmosphere, which help determine the movement of air pollution across Texas.
Trajectories that show the movement of air over metropolitan areas of Texas for the past 30 days. Used to better understand the behavior and potential impact of air pollution.
Meteorological Data for Air Dispersion Modeling
Compressed (zipped) ASCII files of datasets—use when air dispersion modeling is required for an air permit application, modification, or other permit action.
Texas Meteorological Satellite Images – GOES
Geostationary Operational Environmental Satellites images of Texas.
Texas Climatology 1974-2003
Average precipitation and snowfall, average minimum and maximum temperatures, and highest and lowest temperatures recorded across the state.
Illustrations of wind direction movement at particular Texas cities from 1984 to 1992, used to help predict long-term air quality.
