COMEX Project AVIRIS-NG Flight Lines and Data Access, 2014

May through September 2014 flight lines and access information for the AVIRIS-NG airborne instrument used in the CO2 and Methane eXperiment (COMEX). This NASA dataset catalogs flights over Los Angeles, California, providing links to Level 1B Calibrated Radiance and Level 2 Calibrated Reflectance data. It was created to demonstrate the detectability of methane emissions from fossil fuel production for space-based observation validation.

Use Cases

• Mapping airborne survey paths for methane plume detection studies using flight line geometry.
• Linking to calibrated radiance and reflectance data products for spectral analysis.
• Providing temporal and spatial context for the 2014 COMEX campaign over Los Angeles.
• Supporting validation studies for satellite-based methane emission monitoring techniques.

Strengths

• Provides direct access links to primary Level 1B and Level 2 AVIRIS-NG data products.
• Focuses on a specific, well-documented scientific campaign (COMEX) from May-September 2014.
• Cross-platform presence on Data.gov and NASA Earthdata indicates established curation and importance.

Limitations

• Core dataset details like row count, column names, and file size are unknown across all sources.
• Conflicting 'last updated' dates: Data.gov shows 2026 (likely a metadata error), while NASA Earthdata shows 2014.
• License is specified as 'other-license-specified' on Data.gov but is 'None' on NASA Earthdata, creating ambiguity.
