Australia's Integrated Marine Observing System provides sea surface temperature maps composited from VIIRS and AVHRR satellite sensors. The data is a 6-day average of daytime observations, gridded at 0.02-degree resolution over the region from 70E to 170W and 20N to 70S. Each pixel's quality is remapped using Sensor Specific Error Statistics before compositing.
Use Cases
- Modeling ocean heat content based on multi-sensor SST composites
- Analyzing regional SST trends based on 6-day averaged daytime data
- Validating satellite-derived SST products based on quality remapping using SSES
- Studying marine ecosystem responses based on high-resolution SST skin measurements
Strengths
- Multi-sensor product derived from VIIRS and AVHRR satellites, likely increasing data coverage and reliability
- Gridded at a high 0.02-degree resolution, providing detailed spatial information
- Quality levels remapped using Sensor Specific Error Statistics (SSES) as described in Griffin et al. (2017)
- Data covers a large geographic region (70E to 170W, 20N to 70S) relevant to Australian and Southern Hemisphere oceanography
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
Provenance
- Source
- Australian Ocean Data Network
- Collection Method
- Derived from sea surface temperature retrievals from VIIRS and AVHRR sensors on Suomi-NPP, JPSS, NOAA, and Metop satellites.
