As noted by @amoebaliz, the GLORYS SST comparison weights the statistics by area, but the OISST comparison doesn't:

CEFI-regional-MOM6/diagnostics/physics/sst_eval.py

Line 105 in 42d3647

    
           annotate_skill(mom_rg, oisst_ave, grid[2], dim=['lat', 'lon'], x0=config['text_x'], y0=config['text_y'], xint=config['text_xint'], plot_lat=config['plot_lat'])

Since the OISST comparison is done on a regular lat/lon grid, it should be possible to simply use cosine(lat) as the weights.
