Himawari-8 satellite sea surface temperature data used to map the East Australian Current's spatial structure and temporal evolution. The dataset covers the period from July 2015 to September 2017. The research was published in the Journal of Geophysical Research: Oceans in 2020.
Use Cases
- Tracking the meanders and offshoots of the East Australian Current based on its sea surface temperature signature.
- Analyzing the temporal evolution of eddy-shedding events based on the described 65-100 day timescales.
- Investigating seasonal cycles in current encroachment based on the described austral summer/winter patterns.
- Relating sea surface temperature signatures to surface current speeds based on the described 60% overlap metric.
Strengths
- Uses very high spatiotemporal resolution Himawari-8 SST images.
- Covers a 26-month study period from July 2015 to September 2017.
- Enables mapping of complex spatial structures like meanders, eddies, and extensions.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update was 2026-06-16.
