SMEX03 Microwave Brightness Temperature Data for Georgia

Georgia, USA, is the geographic focus of this brightness temperature dataset collected by the Special Sensor Microwave/Imager (SSM/I) during the Soil Moisture Experiment 2003 (SMEX03). The dataset is produced by the National Aeronautics and Space Administration (NASA) and contains measurements from the 2003 field campaign. Its cross-platform presence on government data portals indicates its established role in soil moisture and remote sensing research.

Use Cases

• Calibrating and validating soil moisture retrieval models using passive microwave brightness temperatures.
• Analyzing temporal changes in land surface emissivity during a controlled field experiment.
• Comparing satellite-derived microwave observations with ground-based soil moisture measurements from the SMEX03 campaign.

Strengths

• Data originates from a controlled NASA field experiment (SMEX03) designed for soil moisture validation.
• Dataset is hosted on multiple official government platforms, signaling reliability and ongoing curation.

Limitations

• Critical metadata such as row count, file size, and specific column names are unavailable across all sources.
• A significant conflict exists in the 'last updated' date: one platform shows 2003-09-29, while another shows a future date of 2026-03 12.
