A 0.02° x 0.02° resolution map of sea surface temperature (SST) skin for a single daytime period, derived from the VIIRS instrument on the Suomi-NPP satellite. The Australian Ocean Data Network provides this product, which covers the region from 70°E to 170°W and 20°N to 70°S. Each grid cell contains a 1-day average of the highest quality SSTs, weighted by the area of overlap from multiple swaths.
Use Cases
- Monitoring daily sea surface temperature anomalies based on the 0.02° resolution grid.
- Validating oceanographic models using daytime-only satellite observations.
- Analyzing spatial temperature patterns in the Australian region based on the defined geographic bounds.
- Studying short-term SST variability using the single-day composite product.
Strengths
- Data is derived from the VIIRS instrument on the Suomi-NPP satellite, a specific sensor source.
- Product has a defined spatial resolution of 0.02° x 0.02° and covers a specific region (70°E to 170°W, 20°N to 70°S).
- Quality levels are remapped using original ACSPO VIIRS L3U levels and Sensor Specific Error Statistics (SSES).
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.
- Data may reflect geographic/temporal bias inherent to data_gov_au, focusing on a single daytime period.
