SMEX04 SCAN Soil and Atmospheric Sensor Data from Arizona

SMEX04 Soil Climate Analysis Network (SCAN) Data: Arizona, Version 1 contains automated sensor measurements from a field experiment in 2004. The dataset captures soil and atmospheric conditions from a station in southern Arizona, USA. Documentation was provided by the Principal Investigators and is not formally reviewed by NSIDC, which may limit support.

Use Cases

• Calibrating remote sensing soil moisture algorithms using in-situ soil moisture and temperature measurements.
• Analyzing relationships between atmospheric variables like solar radiation, humidity, and surface soil conditions.
• Studying diurnal and seasonal cycles of land surface temperature and air temperature in a semi-arid environment.
• Investigating the coupling between precipitation events, wind speed, and subsequent changes in soil water content.

Strengths

• Data originates from a controlled field experiment (Soil Moisture Experiment 2004) designed for validation.
• Includes multiple concurrent sensor measurements covering soil and atmospheric variables.
• Time-series data is automatically recorded, providing consistent temporal resolution.

Limitations

• Documentation is not formally reviewed or edited by the hosting organization (NSIDC), potentially limiting usability.
• Key technical details like row count, file size, and specific column names are unavailable across all sources.
• Conflicting 'last updated' dates (2004-09-30 and 2026-03 12) create uncertainty about metadata maintenance.
