Australia's ocean region from 70°E to 170°W and 20°N to 70°S is covered by this sea surface temperature (SST) product. It is a Level 3C (L3C) single-day average derived from daytime passes of the AVHRR instrument on NOAA-19 satellites, gridded at 0.02-degree resolution. The Australian Ocean Data Network provides this data, with referenced accuracy metrics from 2014.
Use Cases
- Validate satellite SST algorithms based on reported biases and standard deviations.
- Model regional ocean heat content based on daily averaged skin temperature data.
- Assimilate SST observations into numerical weather prediction models based on gridded temperature fields.
- Study diurnal warming cycles based on daytime-only satellite passes.
- Calibrate other SST sensors using this product as a reference based on its documented accuracy.
Strengths
- Provides documented accuracy metrics: typical 2014 biases of < 0.1 degC and standard deviations of 0.5 degC to 0.6 degC.
- Offers a consistent spatial grid at 0.02-degree resolution over a defined region.
- Derived from a specific, high-quality source: the AVHRR instrument on NOAA-19 satellites.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect temporal bias inherent to data_gov_au, as accuracy metrics are from 2014.
- Row count is unknown, which may limit suitability assessment for large-scale analyses.
