Field notes
The described method matches model grids to city and town boundaries, weighting areas according to where people live. NASA GEOS-CF supplies the stated PM2.5 and ozone estimates, while Copernicus ERA5-HEAT supplies heat- and cold-stress estimates; the score gives those two measures equal weight. The page displays example readings, but says the full monthly edition is still loading pending file verification.
