Description

Processed marine heatwave metrics are provided for the tropical western and central Pacific Ocean region (120°E-140°W, 40°S-15°N). The metrics are computed from daily sea surface temperature (SST) data, from both observations and models. The observed marine heatwave data are calculated from NOAA 0.25° daily Optimum Interpolation Sea Surface Temperature (OISST) over the period 1982-2019. The modelled marine heatwave data are from analysis of 18 model simulations as part of the Coupled Model Intercomparison Project, Phase 6 (CMIP6) over the period 1982-2100, where two future scenarios have been analysed. Marine heatwaves are computed with respect to the 1995-2014 climatology. The marine heatwave data are provided on a grid point basis across the domain. Marine heatwave timeseries metrics are also provided for three case study regions: Fiji, Samoa, and Palau.

Notes

We acknowledge the World Climate Research Programme's Working Group on Coupled Modelling, which is responsible for CMIP, and we thank the climate modelling groups for producing and making available their model output. CMIP6 model outputs were made available with the assistance of resources from the National Computational Infrastructure (NCI), which is supported by the Australian Government. NOAA High Resolution SST data were provided by the NOAA National Centers for Environmental Information. JBK, NJH, and PP acknowledge ongoing support from the Australian Research Council Centre of Excellence for Climate Extremes (CE170100023). JBK, VH, and NJH acknowledge support from the Australian Government's National Environmental Science Programme (NESP) Earth Systems and Climate Change Hub (Project 5.8). JBK and NJH acknowledge further support from the Climate Systems Hub under phase 2 of NESP. We acknowledge Eric Oliver for the use of his marineHeatWaves python module, freely available at https://github.com/ecjoliver/marineHeatWaves.
