IMOS SNPP: Daily Ocean Chlorophyll-a Concentration via OC3 Algorithm

Satellite-derived chlorophyll-a concentration data from the SNPP platform's VIIRS sensor. The data is processed using the OC3 algorithm recommended by NASA's Ocean Biology Processing Group and implemented in SeaDAS software. It is provided by the Australian Ocean Data Network and was last updated in July 2026.

Use Cases

• Monitoring phytoplankton biomass dynamics based on inferred chlorophyll-a concentration.
• Studying ocean primary productivity patterns based on multi-spectral satellite measurements.
• Validating biogeochemical ocean models based on satellite-derived chlorophyll-a data.
• Assessing water quality and algal bloom events based on chlorophyll-a concentration estimates.

Strengths

• Uses the NASA-recommended OC3 algorithm for chlorophyll-a retrieval.
• Data is derived from the VIIRS sensor on the SNPP satellite platform, a known source for ocean color data.
• Last updated date is explicitly provided as 2026-07-10 02:43:19.156412.

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.
