New Plymouth's air quality benefits from its exceptional Taranaki Province's Tasman Sea coastal position adjacent to Mount Taranaki volcano, with consistent Tasman Sea westerlies providing reliable and often powerful maritime ventilation. Vehicle traffic on surrounding roads and the petroleum, dairy, and manufacturing corridor contribute local sources, while the outstanding coastal exposure generally maintains New Plymouth among New Zealand's more moderately ventilated major coastal provincial cities and Mount Taranaki's occasional volcanic activity adds a distinctive geological dimension.

When is air pollution at its worst in New Plymouth?

New Plymouth usually sees its poorest air quality when road traffic as well as textile and manufacturing operations 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 New Plymouth 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.
