The Coral Reef Temperature Anomaly Database (CoRTAD) Version 2 - Global, 4 km Sea Surface Temperature and Related Thermal Stress Metrics for 1982-2008 (NCEI Accession 0054501)

The Coral Reef Temperature Anomaly Database (CoRTAD) Version 2, developed for coral reef ecosystem applications, offers global weekly sea surface temperature (SST) data from 1982 to 2008 at approximately 4 km resolution. It includes additional years compared to Version 1, and unlike Version 1's HDF4 format, Version 2 is in HDF5 format. The database provides SST metrics, thermal stress anomalies, and parameters like SSTA Degree Heating Week, designed for climate and ecosystem studies to explore the correlation between coral disease, bleaching, and temperature stress.
