BOREAS TIMS: Thermal Infrared Imagery of Boreal Forests

Level-0 Thermal Infrared Multispectral Scanner (TIMS) imagery was collected during the Boreal Ecosystem-Atmosphere Study (BOREAS) to provide spatially extensive data over primary research areas. The uncalibrated images cover two distinct periods in 1994: April 16-20 and September 6-17. Companion files include an image inventory and thumbnail examples for data discovery and download.

Use Cases

• Analyzing forest canopy thermal properties based on uncalibrated thermal infrared imagery.
• Studying land surface reflectance changes between spring and fall seasons in boreal ecosystems.
• Integrating TIMS data with other BOREAS remotely sensed images for multi-sensor spatial analysis.

Strengths

• Provides data from two distinct time periods in 1994, enabling seasonal comparison.
• Includes companion files like an image inventory and thumbnails to aid data discovery.
• Part of the spatially extensive BOREAS project, suggesting relevance for ecosystem-scale studies.

Limitations

• Image data is in its original uncalibrated format, which likely requires significant preprocessing for analysis.
• Key metadata like file size, row count, and specific license terms are inconsistently reported or missing across platforms.
• The most recent update date (2026) conflicts with the actual data collection period (1994), indicating metadata may not reflect data freshness.
