Australian Ocean Data Network provides satellite-derived chlorophyll-a concentration data. The data is inferred from multi-spectral measurements by the VIIRS sensor on the NOAA20 platform using the Garver-Siegel-Maritorena (GSM) algorithm. The dataset was last updated on 2026-07-13.
Use Cases
- Monitor phytoplankton biomass based on chlorophyll-a concentration estimates
- Study ocean surface layer properties based on multi-spectral satellite observations
- Validate or compare ocean color retrieval algorithms based on the GSM method
Strengths
- Data originates from the NOAA20 satellite platform, a specific sensor source
- Uses the Garver-Siegel-Maritorena (GSM) method, a documented retrieval algorithm
- Last updated on 2026-07-13, indicating recent maintenance
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
