SMEX04 Soil Moisture Data from San Miguel Watershed Transect

SMEX04 San Miguel Watershed Soil Moisture Data: Sonora, Version 1 is an in-situ measurement collection from the Soil Moisture Experiment 2004. The dataset was gathered along a topographical transect in northern Sonora, Mexico, by the NSIDC. Sources indicate last updates in 2004 and 2026, suggesting possible metadata revisions.

Use Cases

• Validating satellite-derived soil moisture estimates using in-situ soil moisture and temperature measurements.
• Analyzing relationships between topography and near-surface hydrology using data from a transect.
• Studying correlations between atmospheric conditions (pressure, temperature, humidity) and soil water content.
• Assessing land cover classification impacts on soil moisture variability within a watershed.

Strengths

• Data originates from a controlled field experiment (Soil Moisture Experiment 2004) designed for satellite validation.
• Includes a diverse collection of in-situ measurements across multiple earth science domains.
• The dataset's presence on multiple official platforms (NASA Earthdata, Data.gov) indicates recognized importance.

Limitations

• Documentation was provided solely by Principal Investigators and not thoroughly reviewed by NSIDC, so support may be limited.
• Sources conflict on the last updated date (2004-08 14 vs. 2026-03-12), creating uncertainty about data or metadata modifications.
• Specific column names, row counts, and file sizes are not provided by any source, hindering detailed assessment.
