Marine heatwave projection output as in Hayashida et al. (2020)

There are two files

grid_spec_simple.nc contains the grid information for OFAM3 (e.g. longitude, latitude, cell area).

mhwout_1982-2018_OFAM_cmip5.nc contains the MHW metrics over 1982-2050 simulated by OFAM3:

It’s a 4D array [3, 69, 1200, 3600], where:

The first dimension refers to the MHW metric (count, total_days, total_icum). ‘count’ is the frequency (number of MHW events in a year), ‘total_days’ is the annual MHW days, and ‘total_icum’ is the total cumulative intensity (degree days). To calculate mean MHW intensity (as in Hayashida et al. (2020)), you need to divide ‘total_icum’ by ‘total_days’.

The second dimension is the years from 1982-2050.

The third and fourth dimensions are the latitude and longitude grid points.
