SMEX04: Vegetation Water Content in Arizona and Sonora

2004 data consists of Vegetation Water Content measurements for two regional study areas: Arizona, USA and Sonora, Mexico. This dataset was collected for the Soil Moisture Experiment 2004 (SMEX04). Documentation was provided solely by the Principal Investigator(s) and support may be limited.

Use Cases

• Calibrating soil moisture remote sensing algorithms based on vegetation water content.
• Modeling land-atmosphere interactions in arid and semi-arid regions.
• Validating satellite-derived vegetation indices with ground-based VWC measurements.

Strengths

• Data is associated with a specific, well-defined NASA field experiment (SMEX04).
• Covers two distinct geographic regions (Arizona, USA and Sonora, Mexico) for comparative study.

Limitations

• Documentation was not reviewed or edited by the hosting platform (NSIDC), indicating potential gaps.
• Column names and data structure are unknown, hindering immediate analysis.
• Sources conflict on the last updated date (2004 vs. 2026), creating uncertainty about metadata maintenance.
