Sentinel-3 OLCI: Daily Coastal Water Quality Data at 300m Resolution

Australian coastal waters are monitored by daily satellite-derived water quality parameters. The data includes chlorophyll-a (Chl-a), colored dissolved organic matter (CDOM), and total suspended solids (TSS) at a 300-meter pixel resolution, produced by CSIRO using the FUB-CSIRO Coastal Water Processor. It is a reprojected Level 2P product derived from Sentinel-3 OLCI imagery, with quality flags applied for data control.

Use Cases

• Monitoring algal bloom dynamics based on chlorophyll-a concentration data
• Tracking sediment plumes and coastal erosion based on total suspended solids (TSS) measurements
• Analyzing dissolved organic carbon transport based on colored dissolved organic matter (CDOM) levels
• Assessing daily changes in coastal water quality for environmental reporting

Strengths

• Daily temporal resolution enables tracking of short-term water quality changes
• Data is produced by CSIRO, a national scientific research organization, using a published processor (FUB-CSIRO Coastal Water Processor)
• Includes multiple quality control flags (standard Level 1 and in_out_OR_combined_flags) for data reliability

Limitations

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