Northcote in Auckland reflects the flat North Shore metropolitan corridor adjacent to Auckland Harbour, with vehicle traffic on surrounding roads and the suburban residential and commercial character contributing local sources. Consistent Pacific westerlies and the Waitemata Harbour breezes provide reliable ventilation, while the generally good New Zealand atmospheric conditions and the maritime exposure maintain Northcote among Auckland's more moderately ventilated northern harbour communities throughout most of the year.

When is air pollution at its worst in Northcote?
Northcote usually sees its poorest air quality when traffic on the surrounding roads along with harbour and shipping traffic coincide with periods when maritime winds die down. Sea breezes typically keep conditions in check, except during still weather. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Northcote based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
