Sentinel-3 OLCI: Daily Ocean Reflectance Data for Australian Waters

Sentinel-3 OLCI reduced resolution daily remote sensing reflectance data is produced by CSIRO for the eReefs project. The product uses the FUB-CSIRO Coastal Water Processor and is placed onto a regular grid using nearest neighbor resampling. Standard and additional quality flags are provided for data control.

Use Cases

• Monitor coastal water quality based on spectral remote sensing reflectance.
• Analyze daily changes in above-water optical properties for marine research.
• Apply quality control workflows using the provided standard and out-of-range flags.
• Study Australian marine regions using the eReefs project's reprojected data.

Strengths

• Data is produced by CSIRO, a national scientific research institution.
• Includes standard Level 1 quality flags and additional algorithm input/output flags for quality control.
• Product is derived from Level 2 geophysical quantities and reprojected onto a regular grid.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
