Himawari-8 Sea Surface Temperature Data for Oceanographic Phenomena

Geoscience Australia provides Himawari-8 satellite data for monitoring dynamic oceanographic phenomena. The data has high temporal frequency (10-minute intervals) and spatial resolution (approximately 2 kilometers). The associated presentation analyzes events from 2015 to 2017, including upwelling on the Bonney Coast and variations in the East Australian Current.

Use Cases

• Monitoring upwelling events based on area, temperature, and duration metrics described for the Bonney Coast.
• Analyzing seasonal and intra-seasonal variations of major currents like the East Australian Current.
• Investigating diurnal sea surface temperature variations linked to the Madden-Julian Oscillation phases.
• Correlating sea surface temperature with surface wind speed and short-wave latent heat flux as indicated in the analysis.

Strengths

• High temporal frequency of 10-minute observations enables tracking of rapid oceanographic changes.
• High spatial resolution of approximately 2 kilometers provides detailed geographic mapping.
• Analysis covers a multi-year period, including specific events from 2015 to 2017.

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 regional phenomena.
