Sentinel-3 OLCI: Daily Water Quality Maps for Australian Coastal Waters

Daily full-resolution (approximately 300m) satellite-derived water quality data for Australian coastal waters, produced by CSIRO under the eReefs Phase 5 project. The dataset includes Level 2P reprojected maps of chlorophyll-a (Chl-a), colored dissolved organic matter (CDOM), and total suspended solids (TSS), generated using the FUB-CSIRO Coastal Water Processor. Data is quality-controlled with standard Level 1 flags and additional algorithm input/output out-of-range flags.

Use Cases

• Monitoring coastal algal blooms based on chlorophyll-a (Chl-a) concentrations.
• Analyzing water clarity and sediment transport based on total suspended solids (TSS) data.
• Tracking dissolved organic matter in coastal zones based on colored dissolved organic matter (CDOM) measurements.
• Developing time-series models for water quality trends using daily satellite observations.

Strengths

• Daily temporal resolution supports time-series and trend analysis.
• Full-resolution data with approximately 300-meter pixel size provides detailed spatial information.
• Includes multiple water quality parameters: Chl-a, CDOM, and TSS.
• Data is produced by the authoritative research organization CSIRO using a peer-reviewed processor.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to its focus on Australian coastal waters via data_gov_au.

Provenance
