NOAA Coral Reef Watch (CRW) Daily Global 5-km (0.05 degree) Satellite Coral Bleaching Heat Stress Monitoring Product Suite

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:03 AM | Dataset Last Updated: August 01, 2026 at 12:00 AM
The NOAA Coral Reef Watch (CRW) daily global 5-km (0.05 degree) satellite coral bleaching heat stress monitoring product suite (currently Version 3.1, released August 1, 2018) is a next-generation version of CRW's twice-weekly global 50-km (0.5 degree) satellite monitoring product suite. The 5-km suite currently includes sea surface temperature (SST, also known as "CoralTemp"), SST Anomaly, Coral Bleaching HotSpot (HS), Degree Heating Week (DHW), and Bleaching Alert Area (BAA) products, along with a 7-day maximum BAA and a 7-day SST Trend product. It also includes Year-to-date, Monthly, as well as Annual composite (maximum, minimum, and mean) products based on the daily products. This 5-km product suite provides service at or near reef-scales, allowing direct monitoring of the majority of coral reefs globally and significantly reducing data gaps (caused by cloud cover) that were present in the heritage 50-km products. The 5-km products now comprise the core of CRW's next-generation Decision Support System (DSS) for coral reef management. File formats provided are: netCDF and PNG.
