MASTER Airborne Multispectral Imagery and Land Surface Temperature for Western USA

Fifteen NASA ER-2 aircraft flights over California, Arizona, Oregon, and Nevada collected this dataset in summer 2018. It provides Level 1B calibrated radiance imagery across 50 spectral bands and derived Level 2 products including land surface temperature and emissivity. The campaign supported the HyspIRI mission preparatory work and involved the Student Airborne Research Program.

Use Cases

• Calibrating and validating satellite land surface temperature and emissivity retrieval algorithms using the L2 data products.
• Analyzing surface radiative properties across diverse western US landscapes with 50-band multispectral radiance data.
• Studying spatial patterns of thermal emissions using the 5-band thermal infrared emissivity product.
• Mapping flight paths and correlating spectral measurements with ground features using included georeferenced imagery and ancillary data.

Strengths

• Contains data from 15 distinct airborne flights, providing multiple observational samples.
• Offers both raw sensor data (L1B radiance) and higher-level science products (L2 temperature/emissivity).
• Covers a broad spectral range from 0.460 to 12.879 micrometers across visible and infrared wavelengths.
• Includes ancillary materials like flight paths, instrument configuration, and browse images for context.

Limitations

• Specific row counts, file sizes, and a complete column list are not provided by any source.
• Sources conflict on the last updated date, listing either 2018-09-06 or 2026-03 13.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
