Himawari-8 Sea Surface Temperature Data for Australian Ocean Phenomena

Himawari-8 satellite data provides high-frequency sea surface temperature observations at 10-minute intervals and approximately 2-kilometer resolution. The dataset was used to investigate upwelling events on the Bonney Coast, the East Australian Current, and Madden-Julian Oscillation diurnal variations between 2015 and 2017. The analysis was presented at the 2019 Australian Marine Science Association conference and is associated with the Australian Ocean Data Network.

Use Cases

• Monitoring upwelling events based on area of influence, minimum temperature, and duration described for the Bonney Coast.
• Analyzing seasonal and intra-seasonal variations of the East Australian Current (EAC) based on its mapped encroachment into coastal areas.
• Investigating diurnal sea surface temperature (dSST) variations correlated with Madden-Julian Oscillation (MJO) phases and surface wind speed.
• Studying the relationship between short-wave latent heat flux and diurnal sea surface temperature warming.

Strengths

• High temporal resolution of 10-minute intervals for observing rapid oceanographic changes.
• High spatial resolution of approximately 2 kilometers for detailed regional analysis.
• Covers a multi-year time range, including specific analysis for the 2015-16 and 2016-17 summer seasons.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on Australian coastal regions.
