SMEX04 Soil Moisture Experiment Field Photographs from Arizona and Sonora

2004 field photographs document regional study areas in Arizona, USA and Sonora, Mexico for the Soil Moisture Experiment (SMEX04). The dataset provides visual context of land surface conditions during the campaign. Documentation was provided by the Principal Investigator(s) and support may be limited.

Use Cases

• Visual validation of land cover types for soil moisture model calibration.
• Providing ground-truth context for satellite-based soil moisture observations.
• Documenting field site conditions and vegetation states during the 2004 experiment.

Strengths

• Provides direct visual evidence from a major, focused soil moisture field campaign (SMEX04).
• Covers two distinct arid and semi-arid regions (Arizona, USA and Sonora, Mexico).

Limitations

• Documentation and support are limited as it was not fully reviewed or edited by NSIDC.
• Key metadata such as column names, row counts, and exact number of photographs are unknown.
• Conflicting last updated dates exist across platforms (2004-08-25 vs 2026-03 12).
