MASTER Airborne Imagery for Western Diversity Time Series Campaign

MASTER instrument data from the Western Diversity Time Series airborne campaign includes Level 1B and Level 2 products. The dataset contains calibrated radiance imagery across 50 spectral bands and derived land surface temperature and emissivity from nine NASA ER-2 flights over California and Nevada in spring 2021. It is provided by ORNL_CLOUD and serves as a benchmark for ecosystem state and change assessment.

Use Cases

• Vegetation type and health classification using 50-band multispectral radiance data.
• Land surface temperature and thermal emissivity analysis from five derived thermal infrared bands.
• Ecosystem change benchmarking by comparing calibrated radiance across the 2021 campaign timeframe.
• Spatial analysis of natural disaster impacts (wildfires, drought) using georeferenced imagery at ~50m resolution.
• Flight path and instrument configuration review for campaign metadata and data collection context.

Strengths

• Contains 50 spectral bands of calibrated radiance data, providing detailed spectral coverage from 0.460 to 12.879 micrometers.
• Includes derived Level 2 products for land surface temperature and emissivity in five thermal infrared bands (8.58-12.13 µm).
• Data collected over nine coordinated flights, offering systematic spatial coverage of target areas in California and Nevada.

Limitations

• Exact file size, row count, and specific column names are not provided by any source.
• Sources conflict on license (other-license-specified vs. null) and last updated date (2026-03-13 vs. 2021-04-02).
• Spatial resolution is approximate (~50 meters), which may limit analysis for very fine-scale features.
