SMEX03 ENVISAT ASAR Radar Images for Soil Moisture

Browse images were acquired over Alabama, Georgia, and Oklahoma as part of the 2003 Soil Moisture Experiment. The dataset originates from the ENVISAT ASAR instrument and is provided by the NSIDCV0 organization. Data files are available in BIN, ISO, and HTML formats.

Use Cases

• Analyzing radar backscatter signals to estimate surface soil moisture levels.
• Calibrating and validating soil moisture models using regional field experiment data.
• Studying land cover influences on microwave remote sensing signatures.

Strengths

• Data is part of a coordinated field experiment (SMEX03) designed for soil moisture validation.
• Provides geospatial coverage for three distinct regional study areas in the USA.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating established use.

Limitations

• Sources conflict on the last updated date (2003-07-15 vs 2026-03 12).
• Specific row counts, file sizes, and detailed column/attribute information are unavailable.
