Methodology
The U.S. National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch (CRW) program has developed a daily global 5 kilometer (km) product suite based on satellite observations to monitor Sea Surface Temperature and thermal stress on coral reefs. Data is recorded every 7-day period. It is compatible with Coral Reef Watch's heritage twice-weekly global 50 km Bleaching Alert Area product, as the 50 km Bleaching Alert Area is based on a half-week (3 or 4 days) composite of 50 km Sea Surface Temperature
Data description
The Coral Bleaching Monitoring dataset draws its layers from Version 3.1 of NOAA Coral Reef Watch’s experimental coral bleaching heat stress monitoring product suite. This product suite spans January 1, 1985 to present and is derived from CRW's Version 3.1 daily global 5 km satellite sea surface temperature (SST) data product known as 'CoralTemp'.
The Version 3.1 product suite was developed based on user requests and in order to address errors that were identified in the source SST data for CRW's Version 3.0 products for some coral reef regions during 2013-2016. It now comprises the core of CRW's Decision Support System (DSS) for coral reef management, providing service at or near reef-scales, allowing direct monitoring of 95% of global coral reefs and significantly reducing data gaps caused by cloud cover.
