SMEX04 Arizona Soil Characteristics from Multi-Layer Database

SMEX04 Soil Characteristics data provides soil property measurements for Arizona, USA, collected during the 2004 Soil Moisture Experiment. The dataset was extracted from a multi-layer soil characteristics database for the conterminous United States and processed using ESRI ArcMap software. It is provided by the National Aeronautics and Space Administration (NASA).

Use Cases

• Validating satellite soil moisture retrievals using ground-based soil texture and bulk density measurements.
• Modeling hydrological processes by analyzing soil porosity and water content parameters.
• Characterizing regional terrain for climate studies using elevation data alongside soil classification.
• Studying land-atmosphere interactions by correlating soil moisture content with other soil properties.

Strengths

• Data originates from a multi-layer soil characteristics database covering the conterminous United States, providing regional context.
• Includes multiple specific soil property measurements such as bulk density, texture, porosity, moisture content, and elevation.

Limitations

• Documentation was provided solely by the Principal Investigators and not reviewed by NSIDC, leading to potentially limited support.
• Key technical details like row count, file size, and specific column names are unavailable across all sources.
• Sources conflict on the last updated date, listing either 2004-12-31 or a future date of 2026-03-12.
