BOREAS AOCI: Aquatic Remote Sensing Imagery from 1994

Level-0 AOCI imagery was collected on a single flight on 21-Jul-1994 to provide spatially extensive radiant energy information over the BOREAS study areas. The instrument's wavelength bands were specific to investigating aquatic parameters like chlorophyll content and turbidity. Companion files include an image inventory and example thumbnails for data access.

Use Cases

• Estimating chlorophyll content in water bodies based on specific AOCI wavelength bands.
• Assessing water turbidity levels from calibrated remote sensing imagery.
• Studying radiant energy over forest ecosystems as part of the broader BOREAS investigation.
• Developing or validating algorithms for aquatic parameter retrieval from airborne imagery.

Strengths

• Data has a precise collection date of 21-Jul-1994 and location (SSA - BOREAS study area).
• AOCI was the only instrument flown with bands specific to aquatic parameters like chlorophyll and turbidity.
• Dataset is hosted by the National Aeronautics and Space Administration, indicating authoritative provenance.

Limitations

• Metadata completeness is low: column names, row counts, and exact file sizes are unknown across all sources.
• There is a significant conflict in 'last updated' dates between platforms (1994 vs. 2026), creating uncertainty about metadata maintenance.
• Data is from a single flight, limiting temporal coverage and potentially spatial extent.
