SHIFT: Dried Ground Leaf Spectral Reflectance

Full-spectrum (350-2500 nm) reflectance measurements cover dried ground leaf samples from meadow, shrub, and tree sites. Samples were collected from February 23 to September 27, 2022 for the NASA SBG High Frequency Time series campaign in Santa Barbara County, California. These data support validation of airborne imaging spectroscopy for vegetation biochemistry.

Use Cases

• Validating airborne Visible to ShortWave Infrared (VSWIR) imaging spectroscopy data based on coincident field measurements.
• Modeling vegetation biochemistry and leaf characteristics using full-spectrum reflectance.
• Analyzing spectral-temporal patterns across meadow, shrub, and tree biomes.
• Calibrating satellite-derived vegetation indices with ground-truthed laboratory spectra.

Strengths

• Provides detailed, laboratory-grade spectral reflectance across the full 350-2500 nm range.
• Samples were processed with standardized, documented methods (Serbin et al. 2014, Wang et al. 2020).
• Data collection is part of a coordinated NASA campaign (SHIFT) designed for high-frequency time series validation.

Limitations
