MASTER: Airborne Multispectral and Thermal Data for HyspIRI Mission Prep

Eleven NASA ER-2 flights collected 50-band multispectral radiance and derived land surface temperature data over California and Nevada in fall 2013. This dataset provides Level 1B calibrated radiance and Level 2 emissivity and temperature products at approximately 50-meter spatial resolution. It was gathered as a preparatory campaign for the Hyperspectral Infrared Imager (HyspIRI) mission.

Use Cases

• Validating land surface temperature algorithms using the derived L2 temperature product.
• Analyzing surface emissivity variations across landscapes with the 5-band thermal infrared data.
• Simulating future HyspIRI satellite observations with the 50-band multispectral radiance imagery.
• Conducting regional environmental studies over California and Nevada using the georeferenced flight data.

Strengths

• Covers 11 distinct airborne flights, providing multiple observational snapshots.
• Includes both raw radiance (50 bands) and derived physical products (emissivity, temperature).
• Data is georeferenced and collected at a consistent ~50-meter spatial resolution.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided.
• Conflicting 'last updated' dates exist between platforms (2013-12-05 vs. 2026-04-10), creating uncertainty about maintenance.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
