NOAA20 VIIRS Satellite Data: Daily Chlorophyll-a Concentration via OC3 Model

Australian Ocean Data Network provides satellite-derived chlorophyll-a concentration data from the NOAA20 platform's VIIRS sensor. The data uses the OC3 algorithm recommended by NASA's Ocean Biology Processing Group and processed with SeaDAS software. The dataset was last updated on 2026-07-10.

Use Cases

• Monitoring phytoplankton bloom dynamics based on chlorophyll-a concentration.
• Studying ocean primary productivity and carbon cycling based on satellite-derived pigment data.
• Validating biogeochemical ocean models based on remote sensing observations.
• Assessing coastal water quality and eutrophication based on inferred chlorophyll levels.

Strengths

• Data originates from the NOAA20 satellite platform, a recognized operational environmental satellite.
• Uses the OC3 algorithm, a standard method recommended by NASA's Ocean Biology Processing Group.
• Last updated on 2026-07-10, indicating recent maintenance.

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's coverage and the data_gov_au source.
