HighResCoralStress is a statistically downscaled thermal stress dataset at 0.01° / 1 km spatial resolution for 420,334 global coral reef pixels for historical (1985-2019) and future (2020-2100) time periods. The methodology for generating the HighResCoralStress dataset is detailed in the following PLOS Climate paper.

We provide eight thermal stress metrics which can be visualised and downloaded on the Data page. Thermal stress datasets can be visualised by selecting layers on the left-hand side of the map (e.g. metric, time period, emissions scenario).

The daily downscaled SST data are available from CEDA:

The authors thank all the data providers whose datasets have fed into HighResCoralStress including the following observed datasets:

The authors acknowledge the World Climate Research Programme, which, through its Working Group on Coupled Modelling, coordinated and promoted CMIP6. The authors thank the climate modelling groups for producing and making available their model output, the Earth System Grid Federation (ESGF) for archiving the data and providing access, and the multiple funding agencies who support CMIP6 and ESGF.

Historical, SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5 r1i1p1f1 simulations were used for all models except NESM3 (no SSP3-7.0 available at time of download) and GFDL-CM4 (no SSP1-2.6 and SSP3-7.0 available at time of download).
