California Foliar Chemistry Data for NASA SHIFT Campaign 2022

Santa Barbara County, California, USA hosts this dataset of laboratory foliar chemical analysis results from the 2022 NASA SBG SHIFT campaign. It contains 16 chemical traits from elemental and fiber analyses for leaf samples collected from three reserves between February and September 2022. The data was gathered by NASA to coincide with weekly AVIRIS-NG airborne spectrometer flights for calibration and validation.

Use Cases

• Calibrating airborne imaging spectrometer data by linking foliar nitrogen, phosphorus, and lignin percentages to spectral signatures.
• Modeling relationships between plant structural components (cellulose, hemicellulose) and micronutrient levels (iron, zinc, copper).
• Analyzing spatial and temporal variation in leaf elemental composition (magnesium, potassium, calcium, sulfur) across coastal California preserves.
• Validating remote sensing-derived estimates of plant biochemical traits against direct laboratory measurements.

Strengths

• Contains 16 precisely measured chemical traits from two standardized lab analyses (elemental and AnkomFiber).
• Data collection was temporally aligned with weekly NASA AVIRIS-NG flights, enabling direct sensor validation.
• Samples cover a 7-month period (2022-02 23 to 2022-09-27) across three distinct California reserves.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date: Data.gov lists 2026-03-12, while NASA Earthdata lists 2022-09-27.
