Chomh maith le CO2, bíonn tionchar ag an eitlíocht ar an aeráid trí astaíochtaí neamh-CO2 amhail ocsaídí nítrigine (NOx), cáithníní súiche, speiceas sulfair ocsaídithe agus éifeachtaí ó ghal uisce, chomh maith le próisis atmaisféaracha arb iad is cúis leo astaíochtaí den sórt sin, mar shampla foirmiú an ózóin agus ciorras conaire comhdhlúthaithe.
In addition to CO2, aviation affects the climate through non-CO2 emissions such as oxides of nitrogen (NOx), soot particles, oxidised sulphur species, and effects from water vapour, as well as through atmospheric processes caused by such emissions, for example the formation of ozone and contrail cirrus.
