SMEX03 Surface Roughness Data for Soil Moisture Experiment

SMEX03 Surface Roughness Data was collected over regional study areas in Alabama, Georgia, and Oklahoma, USA. The dataset is part of the 2003 Soil Moisture Experiment (SMEX03) and is provided by the NSIDCV0 organization. It contains measurements of land surface topography and roughness.

Use Cases

• Validating soil moisture estimates from satellite microwave sensors using ground-measured surface roughness parameters.
• Modeling the impact of land surface topography on radar backscatter coefficients for signal interpretation.
• Analyzing regional variations in surface roughness across different agricultural and natural landscapes in Alabama, Georgia, and Oklahoma.

Strengths

• Data was collected as part of a coordinated, multi-region field experiment (SMEX03) in 2003.
• The dataset has a cross-platform presence on NASA Earthdata and Data.gov, indicating established use and curation.

Limitations

• Specific row counts, column names, and file sizes are not provided by any source, limiting detailed assessment.
• Sources conflict on the last updated date, with one listing 2003-07-31 and others listing 2026-03-12, creating uncertainty about maintenance.
