SMEX03 Microwave Brightness Temperature Data for Brazil

SMEX03 SSM/I Brightness Temperature Data, Brazil, Version 1 contains microwave brightness temperature measurements collected during the 2003 Soil Moisture Experiment. The dataset was produced by the National Aeronautics and Space Administration. Sources disagree on the last update date, with one listing 2004 and another listing a future date of 2026.

Use Cases

• Calibrating and validating soil moisture retrieval models using microwave brightness temperatures.
• Analyzing temporal changes in land surface emission during the SMEX03 field campaign.
• Comparing satellite-derived brightness temperature with in-situ soil moisture measurements for the Brazil region.

Strengths

• Data originates from a focused field experiment (Soil Moisture Experiment 2003) designed for validation.
• Provided by the authoritative source, the National Aeronautics and Space Administration.
• Dataset is available on multiple platforms, indicating recognized importance.

Limitations

• Critical metadata conflicts exist: the last updated date is listed as both 2004-02-28 and a future date of 2026-03 12.
• No column names, row counts, or specific size information are provided by any source.
• The license is ambiguously listed as 'other-license-specified' without details.
