MASTER HyspIRI Airborne Campaign Multispectral and Thermal Data

MASTER L1B and L2 data products from the NASA HyspIRI preparatory airborne campaign include calibrated radiance imagery across 50 spectral bands and derived land surface temperature and emissivity. The dataset covers six flights over California and Nevada from April 16 to May 5, 2015, captured by the MODIS/ASTER Airborne Simulator aboard a NASA ER-2 aircraft. Products are provided in HDF-4, ENVI, and KMZ formats alongside flight paths, instrument configuration, and browse images.

Use Cases

• Validating land surface temperature retrieval algorithms using the 5-band thermal infrared emissivity and temperature products.
• Analyzing surface material composition via 50-band multispectral radiance data from visible to thermal infrared wavelengths (0.460 to 12.879 µm).
• Assessing spatial patterns of radiative properties across California and Nevada landscapes at ~50-meter resolution.
• Supporting preparatory studies for the Hyperspectral Infrared Imager (HyspIRI) mission using flight-specific configuration and ancillary notes.

Strengths

• Data includes both raw calibrated radiance (L1B) and derived geophysical products (L2) like emissivity and land surface temperature.
• Covers a wide spectral range with 50 bands from visible to thermal infrared (0.460 to 12.879 micrometers).
• Provides ancillary data including flight paths, spectral band information, and instrument configuration for each of the six flights.

Limitations

• Key metadata such as row count, dataset size, and specific license terms are not provided across any platform.
• Conflicting last updated dates exist between sources (2015-05-05 on NASA Earthdata vs. 2026-03-13 on Data.gov), suggesting potential metadata inconsistency.
