Product Description
Annual Maximum Degree Heating Week (DHW): For each year during 1985-2021, and at each location, we provide the highest level of accumulated heat stress exposure, measured by Coral Reef Watch's daily global 5km satellite coral bleaching DHW product. Values are derived using the Version 3.1 daily global 5km CoralTemp satellite sea surface temperature (SST) data product.
