Modh agus leasuithe
Cuireann an tInnéacs cúig thomhas le chéile do gach cathair: spás glas in aghaidh an duine, chomh te is a éiríonn na comharsanachtaí is teo, agus trí thruaithíúir aeir (PM2.5, PM10, NO2). Cuirtear gach cathair ó chéad go deireanach i ngach tomhas agus déantar meán de na háiteanna sin, le spás glas á chomhaireamh faoi dhó. Is fearr uimhir níos ísle.
Is éard is teas ann ná teocht dhromchla an talaimh, ní teocht an aeir. Is meastacháin samhlacha iad luachanna cáilíochta an aeir. Is éard is limistéar glas ann ná méid an fhásra a bhraitear leis an satailít, ní airde na gcrann.
