Upper Hutt (Savage Park)

The Upper Hutt site is located on the eastern side of the Hutt River, within Savage Park. This site was established in late 2005 and replaces a previous site at Trentham. The air quality indicators measured at this site are PM10, nitrogen dioxide and carbon monoxide.

 

This site measures the impact of residential, traffic and commercial emissions on air quality. In Upper Hutt, the main source of air pollution is from home heating using wood or coal.

General trends show that PM10 concentrations are highest during winter evenings when people are using fires for home heating, and if there is little wind and clear skies.  PM10, nitrogen dioxide and carbon monoxide levels measured at this site all meet national standards and guidelines. PM10 levels measured at the site improved between 2006 and 2011, but have not changed much since 2012.

    What do the dashboard colours mean for PM10?

    The dashboard colours show how PM10 levels sit in relation to the guideline – from green (less than 10%) to red (more than 100% of the guideline).  The guideline (100%) value for the daily average PM10 is 50 µg/m3 and  20 µg/m3  for the annual average.  There are no guidelines for hourly or monthly data (charcoal colour).

    What is this graph showing me?

    This graph shows how levels of PM10 change on an hourly, daily, monthly or annual basis for the selected time period. The levels depend on local sources of emissions and what the weather is doing.  Emissions from various sources change, depending on whether it’s a weekday or the weekend or at different times of the year (e.g. emissions from home heating goes up in the cold winter months).  Still conditions often lead to high concentrations, as there is no wind to blow away the pollutants in the air.   The PM10 concentrations are shown against the guidelines for air quality (for daily and annual averages), and where concentrations exceed the guideline (red line) this can be a cause for concern, especially if this occurs on a frequent basis. 

    Exceedance data (when available) shows the number of days per year that the concentrations went above 100% of the air quality guideline.

    What do the dashboard colours mean for nitrogen dioxide?

    The dashboard colours show how nitrogen dioxide levels sit in relation to these guidelines – from green (less than 10%) to red (over the guideline).  The guideline (100% value) for the hourly average is 200 µg/m3, for the daily average 100 µg/m3, and 4µg/m3 for the annual average.  There are no guidelines for monthly data (charcoal colour).
