BOREAS Radiometrically Rectified Landsat TM Imagery for Boreal Ecosystem

BOREAS TE-18 team produced a series of 23 radiometrically rectified Landsat TM images for the Southern and Northern Study Areas (SSA and NSA). The dataset provides standardized digital number values, enabling comparison of scenes collected under different atmospheric conditions between 1984 and 1995. ORNL_CLOUD processed the original data received from the Canada Centre for Remote Sensing (CCRS).

Use Cases

• Comparing land cover classification across multiple years using standardized digital number values.
• Studying atmospheric effects on satellite reflectance by referencing scenes to clear-condition base images.
• Analyzing temporal trends in boreal forest regions from 1984 to 1995.
• Validating atmospheric optical thickness measurements from coincident RSS-11 data.

Strengths

• Contains 23 rectified images providing multi-year coverage from 1984 to 1995.
• Images are radiometrically standardized to a clear-atmosphere reference scene for each study area.
• Includes coincident atmospheric optical thickness measurements for reference scenes.

Limitations

• Full-resolution images are not publicly distributed due to copyright and process restrictions; only a 60-m degraded version is available.
• Sources conflict on the last updated date, reporting both 1994-09-19 and 2026-03 -13.
