STAQS: Air Quality Data from Chiwaukee Prairie

STAQS_Chiwaukee-Prairie_Data contains air quality measurements from the Chiwaukee Prairie site, part of NASA's Synergistic TEMPO Air Quality Science mission. The mission integrates observations from the TEMPO satellite, aircraft, and ground stations to map pollutants like NO2, HCHO, ozone, and aerosols. Data collection was conducted during summer 2023 to improve the understanding of air quality science.

Use Cases

• Validating TEMPO satellite Level 2 data products using coordinated ground and airborne measurements.
• Analyzing the temporal and spatial evolution of air pollution events tracked by high-resolution GEO satellite data.
• Improving emission estimates for anthropogenic sources in targeted urban areas like Los Angeles, New York City, and Chicago.
• Studying tropospheric ozone profiles by integrating data from the NASA TOLNet lidar network and Pandora spectrometers.

Strengths

• Integrates data from multiple platforms: TEMPO satellite (launched April 2023), two instrumented aircraft (Gulfstream-V and Gulfstream-III), and ground-based networks.
• Provides repeated high-resolution mapping of key pollutants (NO2, HCHO, ozone, aerosols) up to 3 times daily over targeted cities.
• Dataset is hosted by the authoritative source, NASA, and is present on multiple data platforms.

Limitations

• Critical metadata is missing: specific column names, row counts, and dataset size are not provided on any platform.
• Conflicting 'last updated' dates exist between sources (2026-04-09 on datagov vs. 2023-09-11 on nasa_earthdata).
• The license is ambiguously listed as 'other-license-specified' on datagov but is 'None' on nasa_earthdata.
