Degree Heating Weeks
Degree Heating Weeks (DHW) is a thermal stress metric that quantifies accumulated heat exposure above a coral bleaching threshold, computed from satellite sea surface temperature data. Developed by NOAA's Coral Reef Watch program in 2003, DHW provides a standardized index for predicting and monitoring coral bleaching stress globally. The metric combines intensity and duration of thermal anomalies to estimate cumulative physiological stress on coral colonies.
