MASTER Airborne Imagery and Temperature Data for California

MASTER instrument data from the HyspIRI mission preparatory campaign includes Level 1B calibrated radiance imagery and Level 2 derived products like land surface temperature and emissivity. The dataset covers four NASA ER-2 flights over California from August 18 to 29, 2014, providing 50 spectral bands from visible to thermal infrared wavelengths at approximately 50-meter resolution. It is managed by ORNL_CLOUD and includes flight paths, instrument configuration, and browse images.

Use Cases

• Validating satellite-derived land surface temperature algorithms using the provided L2 temperature and emissivity products.
• Assessing vegetation health and land cover using multispectral radiance data across 50 bands from visible to thermal infrared.
• Calibrating and testing atmospheric correction models with georeferenced, calibrated radiance imagery.
• Studying spatial patterns of surface energy balance using co-located radiance and temperature data over diverse California landscapes.
• Supporting the HyspIRI mission preparatory work by providing airborne simulator data for future sensor and product development.

Strengths

• Provides calibrated radiance data across 50 spectral bands (0.460 to 12.879 µm), enabling detailed spectral analysis.
• Includes derived geophysical products like land surface temperature and emissivity in 5 thermal infrared bands (8.58 to 12.13 µm).
• Covers a specific, focused campaign with four flights over a 12-day period in August 2014, offering temporal consistency.

Limitations

• Spatial resolution is approximately 50 meters, which may be coarse for fine-scale local studies.
• Sources conflict on the last updated date, with one platform listing 2014-08-29 and another listing 2026-03-13, suggesting potential metadata inconsistency.
• Key quantitative details like total file size, row count, and specific column names are not provided across any platform.
