Australia's region from 70°E to 170°W and 20°N to 70°S is covered by a 0.02° x 0.02° gridded map of sea surface temperature (SSTskin). The data is derived from night-time observations by the AVHRR instrument on NOAA-XX satellites, with each grid cell containing a weighted average of the highest quality SSTs for a single night. The Australian Ocean Data Network provides this product as part of the GHRSST suite, with validation references indicating typical biases of < 0.05°C and standard deviations of 0.5°C to 0.6°C for NOAA-18 and NOAA-19 in 2014.
Use Cases
- Analyzing nocturnal sea surface temperature patterns based on the night-time-only data collection.
- Validating satellite SST algorithms based on the documented bias and standard deviation metrics.
- Monitoring ocean temperature changes over the Australian region based on the 0.02° resolution gridded map.
- Integrating Level 3 collated SST data into larger ocean models based on its GHRSST product suite classification.
Strengths
- Provides a spatially continuous map at a 0.02° x 0.02° resolution.
- Focuses on night-time passes, which can reduce diurnal variability effects.
- Validation against buoy data indicates a typical bias of < 0.05°C and standard deviation of 0.5-0.6°C.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
