High resolution global mass coral bleaching dataset Version 2.0

This two-part database is version 2.0 of the global mass coral bleaching database presented in Donner et al. (2017). The updated database is documented in Virgen-Urcelay and Donner (2023).

The first part is a spreadsheet listing raw bleaching observations from 1963 to 2017, developed through outreach to the coral reef research and monitoring community and from observations available in the literature. The spreadsheet in .xlsx format lists each individual bleaching observation and a database legend (see "README").

The second part is the annual probability of bleaching occurrence in a given year between 1985 and 2017 at 0.05° X 0.05° latitude-longitude resolution for all warmwater reef cells, developed via spatial modelling. Probabilities were not estimated for years in which there were no reports or the modeled semi-variograms failed to converge due to the low number of bleaching observations that year. The annual gridded maps are provided in .geotiff format within the zip file.

Please consult the manuscript and the authors before employing this data.
