SNPP VIIRS Satellite Data: Daily Chlorophyll-a Concentration via OCI Model

Satellite-derived chlorophyll-a concentration data from the VIIRS sensor on the SNPP platform. The data are produced using the OCI algorithm recommended by NASA's Ocean Biology Processing Group and processed with SeaDAS software. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-07-13.

Use Cases

• Monitoring phytoplankton biomass and algal blooms based on chlorophyll-a concentration estimates.
• Studying ocean primary productivity and its role in the carbon cycle based on satellite-derived pigment data.
• Validating biogeochemical ocean models using spatially extensive satellite observations.
• Assessing long-term trends in marine ecosystem health based on time-series of ocean color data.

Strengths

• Data originates from the VIIRS sensor on the operational SNPP satellite platform.
• Uses the OCI algorithm, a method recommended and implemented by NASA's Ocean Biology Processing Group.
• Last updated on 2026-07-13, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial/temporal coverage are unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the satellite's coverage and the data_gov_au source.
