SMEX04 Surface Roughness Data for Arizona and Sonora

SMEX04 Surface Roughness Data contains measurements collected over regional study areas in Arizona, USA, and Sonora, Mexico. The dataset was produced as part of the 2004 Soil Moisture Experiment (SMEX04) by the Principal Investigator(s) and archived by NSIDC. Documentation and support for this dataset may be limited as it was not formally reviewed by NSIDC.

Use Cases

• Validating satellite-derived soil moisture estimates using in-situ surface roughness measurements.
• Modeling microwave backscatter for remote sensing studies in semi-arid regions.
• Analyzing land surface characteristics for hydrological studies in the Arizona and Sonora study areas.
• Supporting the calibration of airborne or satellite sensors used in the SMEX04 campaign.

Strengths

• Data is part of a structured scientific campaign, the 2004 Soil Moisture Experiment (SMEX04).
• Provides geospatial coverage for two distinct regional study areas in Arizona, USA, and Sonora, Mexico.

Limitations

• Documentation and support are limited as it was not formally reviewed or edited by the hosting archive (NSIDC).
• Key technical details like row count, column names, and file size are unknown across all platforms.
• There is a conflict in the 'last updated' metadata between platforms (2004-08-25 and 2026-03 12).
