SHIFT: HyTES L1 Brightness Temperature for Santa Barbara County

Santa Barbara County, California, and the nearby ocean are covered by 91 flight scenes of Level 1 brightness temperature data from the HyTES airborne spectrometer. The data, collected on March 23, 2022, covers 1,656 square kilometers and provides 256 spectral bands in the 7.5 to 12 micrometer thermal infrared range. These radiance measurements are used to derive land surface temperature and emissivity, informing models of evapotranspiration and water flux.

Use Cases

• Modeling evapotranspiration and water flux based on derived land surface temperature (LST).
• Detecting sources of air pollution using thermal infrared radiance patterns.
• Analyzing plant community responses to thermal stress across a high-frequency time series.
• Calibrating or validating satellite-derived thermal data with high-resolution airborne imagery.
• Generating Level 3 geophysical products like latent heat flux from the provided radiance data.

Strengths

• Contains 91 discrete flight scenes, providing substantial spatial coverage.
• Covers a specific, high-resolution area of 1,656 square kilometers.
• Data is hyperspectral, with 256 spectral bands in the thermal infrared range.
• Includes multiple ancillary files (ENVI, KML, quicklook) for georeferencing and visualization.

Limitations

• Metadata completeness is low; column names, row counts, and exact file sizes are unknown.
• Conflicting 'last updated' dates (2026-04-09 vs. 2022-03-23) create uncertainty about provenance.
• Data is from a single day (2022-03 23), limiting temporal analysis without other campaigns.
