A regional GHRSST Level 3 collated dataset on a 0.02-degree grid covering the Australasian domain from 70E to 190E and 70S to 20N. The Bureau of Meteorology produces these Integrated Marine Observing System (IMOS) SSTskin products from Himawari-8 satellite retrievals, processed every 10 minutes and composited into 4-hour and hourly products. The product format is compliant with the GHRSST Data Specification (GDS) version 2.
Use Cases
- Monitoring diurnal and seasonal sea surface temperature cycles based on 4-hourly composited SSTskin data.
- Validating oceanographic and climate models using high-resolution (0.02-degree) gridded SST observations.
- Studying marine heatwaves and thermal stress events in Australian coastal waters based on reprocessed multi-swath data.
- Assimilating near-real-time satellite SST data into operational forecasting systems based on the real-time and delayed-mode production.
Strengths
- High spatial resolution on a 0.02-degree rectangular grid.
- Data is produced in both real-time and delayed (reprocessed) modes.
- Processing uses a Radiative Transfer Model (RTTOV12.3) and a Bayesian cloud clearing method.
- Product is compliant with the international GHRSST Data Specification version 2.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
