Hyperion Surface Reflectance Images of Amazon Basin

20 multispectral surface reflectance images were collected by the EO-1 satellite Hyperion sensor at 30-meter resolution, covering the entire Amazon Basin from 2002 to 2005. The data was processed by ORNL_CLOUD using ENVI software and the ACORN atmospheric correction algorithm. Images are distributed in GeoTIFF format with companion ENVI header files.

Use Cases

• Analyzing land cover change using 196-band spectral reflectance data.
• Developing cloud masking algorithms based on the provided reflectance band scatter plot methodology.
• Calibrating other satellite sensors with the atmospherically corrected surface reflectance values.
• Studying Amazon Basin biogeochemistry across a multi-year time series from 2002-2005.

Strengths

• Contains 20 high-resolution (30-m) hyperspectral images, each with approximately 196 calibrated spectral bands.
• Includes rigorous processing: cloud masking, de-streaking, and atmospheric correction using ACORN 1.5pb.
• 18 of the 20 images were georeferenced using corresponding ALI satellite imagery for spatial accuracy.

Limitations

• Cross-source conflict: Last updated date is reported as both 2005-10-01 and 2026-03-13, suggesting potential metadata inconsistency.
• Some images have fewer than the typical 196 spectral bands due to removal of low-response bands.
• Specific row counts, file sizes, and detailed column/band names are not provided in the sources.
