Town Summary
Air quality in this town

The sources shown below (Show +) don't include natural sources, such as sea salt in the air, and these are likely to have a big impact on PM10 concentrations in Kaikoura.

No seasonal variation is shown further below, as there is no current PM monitoring. In other Canterbury towns PM concentrations are highest during winter evenings, when temperatures are coldest and there is little wind.

    The table shows the proportions of the main sources of PM10, PM2.5 and nitrogen oxides (NOx) in this town from home heating, industrial activities, outdoor burning and traffic.  (Indoor, natural and shipping sources are not included in this breakdown). 

    These values come from 2013 data sourced from MfE’s data service.  Consistent methodology was used to calculate these estimates of PM and NOx emissions, which allows comparison between towns throughout New Zealand.  Regional council or unitary authority published emissions information might differ if they were prepared in a different year or used another method. Contact your regional council or unitary authority for more information about PM and other emissions in your area.

What is this graph showing me?

The graph shows the monthly average PM concentrations at one representative site in this town for the year selected. In many towns in New Zealand, PM peaks in the winter when air temperatures and wind speeds are lowest as more people heat their homes during colder weather, and still conditions mean that there is no wind to disperse the air pollutants.
