SMEX02 Aircraft Radiometer Data for Soil Moisture

SMEX02 Aircraft Polarimetric Scanning Radiometer (PSR) Data, Version 1 includes brightness temperature (Tb) and soil moisture measurements. The dataset is produced by the National Aeronautics and Space Administration (NASA). Metadata update dates conflict between platforms, ranging from 2002 to 2026.

Use Cases

• Calibrating and validating satellite-derived soil moisture products using airborne brightness temperature data.
• Analyzing the relationship between microwave brightness temperature and in-situ soil moisture content.
• Studying land surface properties and water content variability during the Soil Moisture Experiment 2002 (SMEX02).

Strengths

• Data originates from NASA, a leading authority in Earth observation.
• Contains core variables for soil moisture research: brightness temperature and soil moisture.

Limitations

• Column names and specific row/record counts are unknown.
• There is a significant conflict in the last updated metadata date between sources (2002 vs. 2026).
