MASTER Airborne Multispectral FireSense Data for Western US

MASTER instrument data captures calibrated radiance in 50 spectral bands from 0.460 to 12.879 micrometers. The dataset comprises georeferenced imagery from 11 NASA B200 flights over four western U.S. states in October 2023, collected for the FireSense project to improve wildland fire management. It includes flight paths, band information, instrument configuration, and browse images alongside the primary HDF-4 files.

Use Cases

• Analyzing post-fire landscape recovery using 50-band spectral signatures.
• Mapping burn severity and vegetation stress from calibrated radiance values.
• Validating satellite-derived fire products with 10-meter resolution airborne imagery.
• Studying thermal infrared emissions from recent fire scars across multiple states.
• Correlating flight path data with spectral measurements for precise geolocation.

Strengths

• Contains 50 discrete spectral bands, providing detailed electromagnetic spectrum coverage from visible to thermal infrared.
• Data was collected during 11 dedicated flights, offering systematic spatial coverage over a multi-state region.
• Imagery is georeferenced and calibrated to radiance, enabling direct scientific analysis.

Limitations

• Specific file sizes, row counts, and total data volume are not provided by any source.
• Sources conflict on the last updated date, listing both 2023-10-26 and 2026-03 13.
• Primary data is in HDF-4 format, which may require specialized software for access and processing.
