Multi-sensor sea surface temperature skin (SSTskin) data composited from VIIRS and AVHRR satellite sensors over one month of consecutive daytime periods. The product is a 0.02-degree resolution cylindrical equidistant projected map covering the region 70E to 170W, 20N to 70S. It is provided by the Australian Ocean Data Network and referenced on the IMOS SST products web page.
Use Cases
- Analyzing regional ocean temperature trends based on the one-month average SSTskin composites.
- Validating ocean model outputs using satellite-derived, quality-weighted sea surface temperature data.
- Studying daytime sea surface temperature variability across the Australian region based on the multi-sensor composite.
Strengths
- Data is derived from multiple satellite sensors (VIIRS on Suomi-NPP/JPSS and AVHRR on NOAA/Metop), likely increasing coverage.
- Grid resolution is specified as 0.02 degrees, providing a detailed spatial scale.
- Quality levels are remapped using original sensor-specific error statistics before compositing.
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.
