Description
NASA's Synergistic TEMPO Air Quality Science (STAQS) mission collected a multi-instrument dataset to validate and enhance observations from the TEMPO satellite. The dataset includes measurements from aircraft, drones, sondes, and ground stations targeting urban areas like Los Angeles, New York City, and Chicago during summer 2023. It provides repeated high-resolution mapping of pollutants including nitrogen dioxide (NO2), formaldehyde (HCHO), ozone, and aerosols.
Use Cases
Validating TEMPO satellite Level 2 data products for trace gases and aerosols.
Analyzing the temporal and spatial evolution of urban air pollution events.
Improving emission estimates for anthropogenic and biogenic sources using multi-platform observations.
Studying vertical profiles of ozone and aerosols from lidar and sonde measurements.
Assessing ground-level particulate matter (PM 2.5) concentrations from drone and surface network data.
Strengths
Data collection is complete for the targeted summer 2023 campaign.
Integrates observations from multiple, sophisticated platforms including two research aircraft with specialized lidar and spectrometer payloads.
Targets specific, high-priority urban areas (Los Angeles, New York City, Chicago) for focused analysis.
Limitations
Column names and dataset sizes (rows, file size) are not provided in any source, limiting immediate usability assessment.
The license is inconsistently specified as 'other-license-specified' without details.
Update dates conflict between platforms, with one showing 2026 and another 2023, creating uncertainty about data currency.
Provenance
Source
National Aeronautics and Space Administration (NASA)
Collection Method
Collected via airborne remote sensing (Gulfstream V & III aircraft, SeaRey), drone (BlueHalo E900 UAV), balloonsondes, and ground-based instruments as part of the STAQS field campaign.
Time Range
Summer 2023
Freshness
2026-04-09 (from datagov), but conflicting with a 2023 date on nasa_earthdata.
Geography
Urban areas in North America, specifically Los Angeles, New York City, and Chicago.
License details are not explicitly provided; users must investigate the specific 'other-license-specified' terms. Data formats include BIN and ISO, which may require specialized software to read.
