Composite Datasets Product Description

Presented here are year-to-date (for the current year), monthly, and annual composites of the NOAA Coral Reef Watch (CRW) Version 3 experimental daily global 5km (0.05 degree) satellite coral bleaching heat stress monitoring products. The high-resolution 5km daily products are based on the NOAA/NESDIS operational daily global 5km geostationary-polar-orbiting (Geo-Polar) Blended Night-only SST Analysis and currently include sea surface temperature (SST), SST Anomaly, Coral Bleaching HotSpot, Degree Heating Week (DHW), and Bleaching Alert Area products. The maximum composites are available for all of these variables; minimum and mean composites are available only for SST and SST Anomaly because the Bleaching Alert Area, DHW, and HotSpot are positive-value-only products.
