SMEX03 Soil Moisture Experiment Regional Site Photographs

Photographs from the 2003 Soil Moisture Experiment (SMEX03) capture regional study areas in Alabama, Georgia, and Oklahoma, USA. The dataset is provided by the National Aeronautics and Space Administration (NASA). It consists of visual documentation supporting the experiment's land surface and soil moisture research objectives.

Use Cases

• Validating satellite-derived soil moisture estimates by comparing them to ground conditions visible in the photographs.
• Classifying land cover types (e.g., vegetation, bare soil) within the SMEX03 study regions.
• Providing visual context for other SMEX03 datasets collected at the same sites and time period.
• Documenting field conditions and site characteristics for reproducibility in soil moisture studies.

Strengths

• Dataset is associated with a defined scientific campaign (the 2003 Soil Moisture Experiment).
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance and curation.

Limitations

• No concrete information on the number of photographs, file sizes, or specific column/attribute details is provided.
• Conflicting 'last updated' dates exist between sources (2003-07-07 on NASA EarthData vs. 2026-03-12 on Data.gov).
