Tropical western and central Pacific marine heatwave data calculated from gridded sea surface temperature observations and CMIP6

Processed marine heatwave metrics are provided for the tropical western and central Pacific Ocean region (120 degrees E 140 degrees W, 40 degrees S-15 degrees 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 degrees 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. The marine heat wave 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.
