COMEX: AVIRIS-Classic Flight Lines for Methane Detection

Los Angeles, California is the focus of this dataset, which catalogs flight lines and data access links for airborne remote sensing missions. The data supports the 2014 CO2 and MEthane eXperiment (COMEX) Project, which aimed to quantify methane emissions from fossil fuel production. It provides contextual flight information and links to calibrated radiance and reflectance data from the AVIRIS-Classic instrument.

Use Cases

• Mapping methane plume locations based on flight path geospatial data.
• Validating space-based emission estimates using calibrated airborne spectral data.
• Analyzing the spatial distribution of fossil fuel emissions referenced in the project description.

Strengths

• Data is associated with a specific, well-documented NASA project (COMEX).
• Provides direct access links to Level 1B and Level 2 calibrated data products.

Limitations

• Column names and dataset size are unspecified across all sources, limiting understanding of structure.
• Conflicting last-updated dates (2014 vs. 2026) suggest metadata may be inconsistent.
