IMOS SST: Multi-Sensor 6-Day Daytime Sea Surface Temperature for Australia Region

A multi-sensor sea surface temperature (SST) product for 6 consecutive daytime periods, derived from VIIRS and AVHRR satellite sensors. The data is provided as a 0.02-degree resolution map over the region 70E to 170W, 20N to 70S, with each grid cell containing a 6-day average of the highest quality SSTs. The dataset is provided by the Australian Ocean Data Network and was last updated in July 2026.

Use Cases

• Analyzing regional sea surface temperature patterns based on the 6-day composite data.
• Validating oceanographic models using the multi-sensor, quality-controlled SST data.
• Studying short-term ocean temperature changes based on the daytime-only satellite observations.

Strengths

• Data is derived from multiple satellite sensors (VIIRS and AVHRR), likely improving coverage and reliability.
• Quality levels are remapped using original sensor-specific error statistics before compositing.
• Spatial resolution is specified as 0.02 degrees, providing a detailed geographic grid.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
