Sentinel-3 OLCI: Daily Coastal Water Reflectance at 1000m Resolution

Sentinel-3 OLCI reduced resolution daily reprojected Level 2P above-water spectral remote sensing reflectance produced by CSIRO under eReefs Phase 5. The data is processed using the FUB-CSIRO Coastal Water Processor and placed onto a regular grid using nearest neighbor resampling. Standard Level 1 quality flags and additional algorithm input/output out-of-range flags are provided for quality control.

Use Cases

• Monitor coastal water quality based on remote sensing reflectance data.
• Analyze daily changes in above-water spectral signatures for environmental studies.
• Apply quality control workflows using the provided Level 1 and out-of-range flags.
• Study phytoplankton dynamics or sediment transport using spectral reflectance.

Strengths

• Data is produced by CSIRO, a national scientific research organization.
• Includes multiple quality flag layers (Level 1 and in_out_OR_combined_flags) for data control.
• Data is reprojected onto a regular grid for easier analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The quality flags have not been applied to pre-mask the data, requiring user intervention.
