MASTER Airborne Imagery of Hawaii Volcanoes and Western US

Eighteen flights from December 2016 to March 2017 collected Level 1B and Level 2 data products from the MODIS/ASTER Airborne Simulator (MASTER) instrument aboard a NASA ER-2 aircraft. The dataset provides calibrated radiance imagery across 50 spectral bands and derived products including land surface temperature and emissivity, focusing on areas in Hawaii, California, and Nevada. It was produced as part of the Hyperspectral Infrared Imager (HyspIRI) airborne campaign.

Use Cases

• Analyzing volcanic thermal activity and surface composition using the 5-band thermal infrared emissivity and land surface temperature products.
• Calibrating and validating satellite-based land surface temperature algorithms with airborne data at approximately 50-meter resolution.
• Studying surface radiative properties across diverse landscapes using calibrated radiance values from 50 spectral bands (0.460 to 12.879 micrometers).
• Mapping flight paths and correlating spectral measurements with specific geographic locations and times using the included ancillary data.

Strengths

• Contains data from 18 distinct flights, providing multiple observational snapshots across the campaign period.
• Offers both raw calibrated radiance (L1B) and scientifically derived products like land surface temperature and emissivity (L2).
• Covers a wide spectral range from visible to thermal infrared (0.460 to 12.879 µm) in 50 discrete bands.

Limitations

• Spatial resolution is approximate (~50m); precise resolution may vary per band or flight condition.
• Key metadata conflicts exist: the 'last updated' date differs between sources (2017-03-03 vs. 2026-03-13).
• The exact data volume, row count, and detailed column schema are not provided by any source.
