NOTICE !!!

NOAA Coral Reef Watch's operational twice-weekly global 50km satellite coral bleaching heat stress monitoring products were retired in April 2020, after being in service for more than two decades
(January 1997 - April 2020).

These products have been replaced with higher-resolution daily global 5km satellite products.
