Himawari-8 Sea Surface Temperature Analysis for Australian Waters

Himawari-8 satellite data provides high-frequency (10-minute) and high-resolution (~2 km) sea surface temperature (SST) observations. This presentation demonstrates its application for investigating the Bonney Coast upwelling, East Australian Current (EAC) seasonal variations, and Madden-Julian Oscillation (MJO) diurnal SST signals from 2015 to 2017.

Use Cases

• Analyze diurnal SST (dSST) variations correlated with surface wind speed and short-wave latent heat flux for MJO phase studies.
• Map seasonal and intra-seasonal variations of the East Australian Current (EAC) extension into coastal areas.
• Investigate distinct upwelling events along the Bonney Coast using metrics like area of influence, minimum temperature, and duration.

Strengths

• Data sourced from the Himawari-8 satellite, providing high temporal (10-minute) and spatial (~2 km) resolution.
• Analysis covers specific, dynamic oceanographic phenomena: the Bonney Coast upwelling, the EAC, and MJO-related dSST.
• Temporal coverage spans from July 2015 to September 2017, capturing multiple seasonal cycles.

Limitations

• The primary input is a conference presentation (PDF/HTML), not a structured, tabular dataset for direct analysis.
• Sample data and column definitions are unavailable, limiting immediate machine learning application.
• Geographic focus is specific to Australian coastal regions and the northwest shelf, not global.
