BOREAS Radiometrically Rectified Landsat TM Imagery

23 Landsat TM images from 1984 to 1995 were processed using a radiometric rectification method to standardize digital number values for comparison across different atmospheric conditions. The dataset covers the BOREAS Southern and Northern Study Areas (SSA and NSA) in Canada. It was produced by the BOREAS TE-18 team, with data managed by ORNL_CLOUD.

Use Cases

• Analyzing temporal changes in boreal forest reflectance using standardized DN values.
• Comparing land surface conditions under varying atmospheric states across a decade.
• Validating other atmospheric correction models against a rectified reference dataset.
• Studying seasonal and interannual variability in the BOREAS SSA and NSA regions.

Strengths

• Contains 23 rectified images, providing a multi-year time series for analysis.
• Covers a significant time range from 22-Jun-1984 to 18-Sep-1994, enabling decade-scale studies.
• Uses a defined radiometric rectification process with clear reference images (02-Sep-1994 for SSA, 21-Jun-1995 for NSA) for standardization.
• Presence on multiple platforms (nasa_earthdata, datagov) indicates established use and importance.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the last updated date: one states 2026-03-13, another states 1994-09-18.
• The license is listed as 'other-license-specified' or 'None', requiring user verification.
