NOAA Coral Reef Watch Operational Near-real-time Twice-weekly Global 50 km Satellite Coral Bleaching Thermal Stress Monitoring Product Suite

NOAA Coral Reef Watch program produces a suite of near-real-time global 50 km monitoring products, based on sea surface temperature (SST) observations from NOAA's Polar-orbiting Operational Environmental Satellites (POES), to pinpoint areas around the world where heat stress is sufficient to cause mass coral bleaching. This product suite is produced twice a week operationally and includes nighttime sea surface temperature, nighttime sea surface temperature anomaly, coral bleaching HotSpot, Degree Heating Week, and Bleaching Alert Area products.
