BOUSSOLE Ocean Optical Properties Time Series

BOUSSOLE project data establishes a long-term time series of optical properties in oceanic waters to support bio-optics research and satellite calibration. The dataset is built from a permanent marine optical buoy and monthly cruises in the Ligurian Sea, a sub-basin of the Western Mediterranean. It is a joint effort funded and supported by multiple international space and research agencies including ESA, CNES, CNRS, and NASA.

Use Cases

• Vicarious calibration of ocean color satellite sensors like SeaWiFS, MODIS, and Sentinel-3.
• Validation of satellite-derived products such as chlorophyll-a concentration and water-leaving radiance.
• Analysis of bio-optical relationships and inherent optical properties (IOPs) in oceanic waters.
• Studying temporal variability of ocean optics and temperature in the Ligurian Sea.
• Performing match-up analyses between in-situ buoy measurements and concurrent satellite overpasses.

Strengths

• Data is sourced from a permanent, dedicated optical buoy and regular monthly cruises, ensuring a consistent collection method.
• Project involves multiple major space agencies (ESA, NASA, CNES), indicating high institutional support and data quality standards.
• Designed specifically for satellite calibration and validation, making it a benchmark dataset for the ocean color community.

Limitations

• Specific row counts, file sizes, and a complete column list are unavailable across all sources, limiting precise technical assessment.
• License information is conflicting: one source specifies 'other-license-specified' while another lists 'None'.
• The dataset's exact temporal coverage (start and end dates) is not provided.
