BOREAS AVHRR-LAC: Ten-Day Composite Radiance Images

Sixteen 10-day composite periods from April 11 to September 10, 1994, provide at-sensor radiance data for the BOREAS study region. These gridded AVHRR Level-4b images from NOAA-11 and -14 satellites were processed to support the Boreal Ecosystem-Atmosphere Study. The dataset is stored in binary image format with companion thumbnail viewers.

Use Cases

• Analyzing seasonal vegetation changes in boreal forests based on 10-day composite radiance values.
• Validating land surface models using spatially extended satellite data from the BOREAS campaign.
• Comparing point-based field measurements with gridded, regional-scale AVHRR imagery.
• Developing or testing remote sensing compositing techniques for reducing cloud cover in time-series data.

Strengths

• Provides a consistent temporal series of 16 distinct 10-day composite periods over a key growing season.
• Covers the entire BOREAS study region, offering spatially complete data for a major ecological campaign.
• Data is hosted on multiple authoritative platforms (Data.gov, NASA EarthData), indicating established provenance and importance.

Limitations

• Key metadata such as row count, file size, and specific column/band information is unavailable across all sources.
• There is a conflict in 'last updated' metadata between platforms (1994 vs. 2026), creating uncertainty about maintenance.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
