Satellite-derived chlorophyll-a concentration data from the SNPP platform's VIIRS sensor. The data uses the Garver-Siegel-Maritorena (GSM) retrieval algorithm processed with SeaDAS software. It is provided by the Australian Ocean Data Network and was last updated on 2026-07-10.
Use Cases
- Monitoring marine phytoplankton blooms based on chlorophyll-a concentration data.
- Studying ocean primary productivity patterns based on satellite-derived bio-optical measurements.
- Validating ocean biogeochemical models based on remote sensing estimates of chlorophyll-a.
- Assessing long-term changes in ocean ecosystems based on time-series satellite data.
Strengths
- Data is derived from the VIIRS sensor on the SNPP satellite platform, a specific source.
- Uses the Garver-Siegel-Maritorena (GSM) method, a defined retrieval algorithm.
- Last update timestamp is precisely recorded as 2026-07-10 15:15:05.422832.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- Data may reflect geographic or temporal bias inherent to the satellite platform's coverage.
