TexAQS2000: Houston Air Quality Formaldehyde and Hydrogen Peroxide Measurements

August-September 2000 continuous measurements of formaldehyde (HCHO) and hydrogen peroxide (H2O2) collected during the Texas Air Quality Study 2000 at the Houston Regional Monitoring Site 3. The dataset contains integrated 3-minute samples collected every 10 minutes. It was produced by the NARSTO EPA Supersite program to characterize particulate matter sources and support health effects studies.

Use Cases

• Modeling atmospheric oxidation chemistry based on concurrent formaldehyde and hydrogen peroxide measurements.
• Analyzing diurnal patterns of volatile organic compound oxidation products based on the 10-minute sampling interval.
• Studying the relationship between fine particulate matter (PM) precursors and secondary pollutant formation in Southeastern Texas.
• Validating air quality model outputs for urban environments based on high-temporal-resolution ground measurements.

Strengths

• High-temporal-resolution data with 3-minute integrated samples collected every 10 minutes.
• Continuous measurements over a defined campaign period (August-September 2000).
• Data collected as part of a coordinated EPA Supersite program with defined scientific goals.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single monitoring station (HRM Site 3), limiting spatial representativeness.
