Sea Surface Temperature (daily, 1982 – present)

What this dataset is

A daily, gap-free global sea-surface temperature dataset on a 0.05° grid, blended from infrared, microwave and in-situ observations. Coverage starts on 1 January 1982 and is updated nightly with a one-day latency.

What you get

• A single global Zarr store, indexed by date, latitude and longitude.
• A monthly NetCDF mirror for file-based workflows.
• Anomaly products against the 1991–2020 climatological baseline.

Typical uses

• Marine heatwave detection and monitoring.
• El Niño / La Niña tracking.
• Coral-bleaching risk forecasting.
• Inputs to ocean, climate and fisheries models.

Notes

For higher-resolution coastal SST, see the regional ocean datasets in the catalogue.
