INTEX-B Aircraft Trajectory Data on Transcontinental Pollution Transport

INTEX-B DC-8 Aircraft Trajectory data captures the transport and transformation of atmospheric pollutants across continents. The dataset originates from a NASA-led field campaign conducted over an 8-week period from March to April 2006, focusing on Asian and North American pollution flows. It was produced by the LARC_ASDC organization to support the INTEX-NA experiment's goals of assessing impacts on air quality and climate.

Use Cases

• Quantifying transpacific transport of Asian pollution to North America using trajectory data.
• Analyzing outflow and evolution of gases and aerosols from the Mexico City Megaplex.
• Investigating transport of pollution to the eastern Atlantic for European air quality assessment.
• Validating and refining satellite observations of tropospheric composition with in-situ campaign data.
• Mapping emissions of trace gases and aerosols by relating atmospheric composition measurements to source and sink regions.

Strengths

• Data is from a coordinated, multi-partner field campaign (INTEX-B, MIRAGE-Mex, DLR/IMPACT) enhancing reliability.
• Campaign focused on specific, high-impact phenomena over a defined 8-week period in Spring 2006.
• Cross-platform presence on NASA EarthData and Data.gov signals recognized scientific importance.

Limitations

• Critical metadata is missing: no column names, row counts, or exact file sizes are provided by any source.
• Conflicting license information: one source lists 'other-license-specified', another lists 'None'.
