Composite Products Description

Presented here are year-to-date (for the current year), monthly, and annual composites of the NOAA Coral Reef Watch (CRW) daily global 5km (0.05 degree) satellite coral bleaching heat stress monitoring products. Year-to-date and monthly composite data and images are available for the Version 3.0 (v3.0) 5km suite; annual composite images are available for the Version 3.1 (v3.1) 5km suite (see the Special Notice for more details). The v3.0 daily 5km products are based on the NOAA/NESDIS operational daily global 5km geostationary-polar-orbiting (geo-polar) blended night-only sea surface temperature (SST) analysis; the v3.1 daily 5km products are based on CRW's CoralTemp v1.0 SST dataset. Products currently include SST, SST Anomaly, Coral Bleaching HotSpot, Degree Heating Week (DHW), and Bleaching Alert Area. Maximum composites are available for all of these variables; minimum and mean composites are available only for SST and SST Anomaly products because the Bleaching Alert Area, DHW, and HotSpot are positive-value-only products.
