DISCOVER-AQ Texas Deployment: Ground Site Air Quality Measurements

Texas Commission on Environmental Quality ground site data collected in Houston, Texas, as part of NASA's DISCOVER-AQ field study. The dataset likely contains surface-level measurements of pollutants and meteorological variables from sites including Aldine, Channelview, Clinton, and West Houston. It was created by NASA in collaboration with universities to validate satellite observations for air quality monitoring.

Use Cases

• Validate satellite column observations of ozone, nitrogen dioxide, and formaldehyde based on surface-level measurements.
• Analyze diurnal variability of pollutants based on ground-based monitoring.
• Investigate horizontal scales of variability and pollution gradients across the Houston region.
• Correlate aircraft in-situ profiling data with concurrent ground site measurements.

Strengths

• Data collection is complete for the Texas deployment.
• Integrates measurements from an existing network of surface air quality monitors, AERONET sun photometers, and Pandora spectrometers.
• Part of a four-year NASA campaign involving multiple research centers and universities.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN, PDF, ISO, HTML, which may require specialized tools for processing.
