MASTER Airborne Imagery of Hawaii Volcanoes and California

Twelve NASA ER-2 flights collected multispectral and thermal infrared data over Hawaii and southern California from January 11 to February 20, 2018. The dataset provides Level 1B calibrated radiance imagery across 50 spectral bands and Level 2 derived products including land surface temperature and emissivity. Data products are managed by ORNL_CLOUD and are available in HDF-4, ENVI, and KMZ formats.

Use Cases

• Analyzing volcanic thermal emissions and surface features using land surface temperature and emissivity bands.
• Calibrating and validating satellite-based thermal infrared sensors with airborne-collected radiance data.
• Studying land surface radiative properties across diverse Californian and Hawaiian terrains.
• Mapping surface composition and temperature gradients at approximately 50-meter spatial resolution.

Strengths

• Data covers 50 spectral bands from visible to thermal infrared (0.460 to 12.879 micrometers).
• Includes derived Level 2 science products: land surface temperature and 5-band emissivity.
• Collection spans 12 specific flights over a focused six-week campaign in 2018.

Limitations

• Exact file size and row/record counts are not provided by any source.
• Sources conflict on the last updated date (2018-02 20 vs. 2026-03-13).
• Column names and detailed data structure are not specified in the available metadata.
