Nelson Centre/North

Nelson Centre/North comprises mainly of residential housing and includes the commercial city centre and Port Nelson area. It extends along a narrow coastal strip crossed by numerous small valleys which drain air from the hills to the sea. 

 

Nelson Centre/North is complex in geography comprising valleys and coastal flats. It includes Britannia Heights, The Brook, Atmore, Maitai, Clifton, The Wood, Trafalgar, Atawhai and Port Nelson. The common characteristic is that it has sufficient air movement created by drainage air flowing out of valleys and coastal breezes to disperse PM10 which prevents high concentrations occurring. It has one PM10 monitoring site.  The main state highway runs to the north of the monitoring site.

Town Summary

    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.
