The GHRSST task team on Coral Heat Stress Task Team updated the report to include other uses of SST regarding coral reef science and management beyond the quantification of heat stress. To requirements for stability, geo-location accuracy, SST accuracy (including high SSTs), SST uncertainty, and timeliness, the update adds requirements for diurnal variation, increased spatial resolution, preservation of oceanographic features such as upwelling, and a measure of effective spatial resolution.
