SMEX03 Soil Characteristics Data for Regional US Study Areas

SMEX03 Ancillary Soil Characteristics data contains geospatial soil property information for the regional study areas of Alabama, Georgia, and Oklahoma, USA. The dataset was extracted from a multi-layer national database and generated using ESRI ArcMap software by the National Aeronautics and Space Administration. It originates from the 2003 Soil Moisture Experiment (SMEX03).

Use Cases

• Analyzing regional soil bulk density for hydrological modeling.
• Studying soil texture and porosity variations across Alabama, Georgia, and Oklahoma.
• Mapping soil classification for agricultural land assessment.
• Correlating soil moisture content with ancillary soil characteristics.

Strengths

• Data is derived from a multi-layer soil characteristics database for the conterminous United States.
• Provides specific coverage for three distinct regional study areas (Alabama, Georgia, Oklahoma).
• Generated using industry-standard ESRI ArcMap software.

Limitations

• Specific row counts, column names, and dataset size are not provided by any source.
• Sources conflict on the last update date, with one listing 2003-07-31 and another listing 2026-03-12.
