Sentinel-3 OLCI Coastal Water Reflectance for Australia

Giving access to daily, reprojected Level 2P remote sensing reflectance data for Australian coastal waters, derived from Sentinel-3 OLCI satellite imagery at approximately 1000-meter resolution. The data is produced by CSIRO using the FUB-CSIRO Coastal Water Processor and includes quality control flags. It is available in PNG, HTML, and WMS formats.

Use Cases

• Analyze spectral remote sensing reflectance patterns in Australian coastal waters to monitor water quality.
• Apply the in_out_OR_combined_flags for quality control and filtering of out-of-range reflectance values.
• Use the pre-applied Level 1 quality flags (file_version_quality_control) to mask unreliable data pixels before analysis.
• Investigate daily changes in above-water reflectance for coastal environmental monitoring and modeling.

Strengths

• Data is derived from Sentinel-3 OLCI satellite imagery, a known source for ocean color observations.
• Includes multiple quality control layers: standard Level 1 flags and additional algorithm input/output flags.
• Data is reprojected onto a regular grid using nearest neighbor resampling for spatial consistency.
• Produced by CSIRO, a national scientific research organization, under the eReefs Phase 5 project.

Limitations

• The spatial resolution is reduced to approximately 1000 meters, limiting fine-scale analysis.
• Specific technical details, such as the exact temporal coverage and data volume (rows, size), are not provided in the input.
• The license is listed as 'notspecified', which may create uncertainty for commercial or redistribution use.
