SMEX04 Arizona Surface Temperature Data from Infrared Thermometers

SMEX04 Surface Temperature Data: Arizona, Version 1 contains in situ infrared thermometer measurements collected during the Soil Moisture Experiment 2004 (SMEX04). The data set is provided by the Principal Investigator(s) via the National Snow and Ice Data Center (NSIDC). Platform records show conflicting last updated dates of 2004-09-30 and 2026-03-12.

Use Cases

• Validating satellite-based land surface temperature products using ground-truth infrared thermometer readings.
• Analyzing diurnal and seasonal temperature variations in Arizona's semi-arid environment.
• Supporting soil moisture retrieval algorithms by providing concurrent surface temperature data.
• Studying land surface thermal properties and their relationship to soil moisture content.

Strengths

• Data originates from a structured scientific field experiment (Soil Moisture Experiment 2004).
• Provides in-situ measurements, a key source for validating remote sensing data.

Limitations

• Documentation was provided solely by the Principal Investigator(s) and not reviewed by NSIDC, indicating potential support limits.
• Key metadata such as row count, file size, and specific column names are unknown across all platforms.
• Platforms disagree on the 'last updated' date, with values of 2004-09-30 and 2026-03-12.
