Little Washita Watershed Soil Moisture and Temperature Data

SMEX03 Little Washita Micronet Soil Moisture Data provides soil conditions from a watershed in southwestern Oklahoma, USA. The dataset is managed by the National Snow and Ice Data Center (NSIDC). Metadata indicates updates as recent as 2026, though a source also lists a 2003 date.

Use Cases

• Analyzing soil moisture-water content for hydrological modeling.
• Studying land surface temperature and soil thermal properties.
• Investigating soil salinity and sodicity impacts on electrical conductivity.
• Validating satellite-derived soil moisture estimates with ground measurements.

Strengths

• Data originates from a specific, instrumented watershed (Little Washita Creek, Oklahoma).
• Covers multiple interrelated land surface variables including moisture, temperature, and conductivity.

Limitations

• Critical details like row count, column names, and exact size are unavailable from all sources.
• Sources conflict on the last updated date, listing both 2003 and 2026.
