TexAQS2000: Houston Air Chemistry and Aerosol Data from 20 Research Flights

Twenty research flights were conducted from August 18 to September 12, 2000. This dataset contains air chemistry, aerosol, and meteorological measurements collected by the Department of Energy's G-1 aircraft during the Texas Air Quality Study 2000. It was produced under the NARSTO EPA Supersite program to characterize particulate matter sources and composition in Southeastern Texas.

Use Cases

• Characterizing particulate matter composition and sources based on the aerosol and air chemistry measurements mentioned in the description
• Developing and testing new methods for fine particulate matter characterization based on the stated study goals
• Supporting exposure and health effects studies based on the physical and chemical characterization data collected
• Analyzing tropospheric pollution behavior and informing air-pollution management strategies based on the NARSTO mission

Strengths

• Data from 20 dedicated research flights provides a focused temporal snapshot
• Covers multiple atmospheric domains: air chemistry, aerosols, and meteorology
• Part of a coordinated Supersite program with defined scientific goals for policy-relevant research

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 specific, short campaign in 2000; temporal generalizability is limited
