Product Description

Annual History metrics: The maximum experienced satellite sea surface temperature (SST), SST Anomaly, and Degree Heating Week (DHW, accumulated heat stress) metrics for each year during 1985-2018 are provided at coral reef-containing and adjacent satellite pixel locations worldwide using the Version 3.1 'CoralTemp' daily global 5km satellite SST data product.

Where relevant, the range of values calculated from analyzed pixels is shown in [brackets] after each metric name.

Annual Maximum SST [20.1-38.3°C], SST Anomaly [-0.7-6.6°C] and DHW [0.0-38.5°C-weeks]: For each year during 1985-2018 and at each location, the warmest SST, the greatest SST Anomaly (i.e., the departure from the expected SST value at each location for that time of year, derived from the monthly climatology; see Climatology page), and the highest DHW are provided.

Within-year SST Average [16.3-30.5°C]: For this metric, the average temperature is determined for each year in the time-series (1985-2018).

Within-year SST Variability [0.18-7.02°C]: For this metric, the standard deviation of temperature is determined for each year in the time-series (1985-2018).
