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.

Scientific data for this site

This dashboard shows the latest results for air quality indicators collected by regional councils and unitary authorities.  Indicators are shown against the National Environmental Standards for Air Quality (NES-AQ).  Where no national standards exist for the air quality measurements shown, the data are compared against other guidelines (e.g. World Health Organization (WHO) 2021 guidelines, Ambient Air Quality Guidelines (AAQG)).

    What is this graph showing me?

    This graph shows how concentrations of PM10 change on an hourly, daily, monthly or annual basis for the selected time period. The number of exceedance days can be viewed over the last 10 years or all years if available.

    The PM10 daily average concentrations and exceedance days are compared to the National Standard (NES-AQ), and the PM10 annual average concentrations are compared to the WHO guideline.  The standard and guideline limits are denoted by the red horizontal line.   There are no guidelines for hourly or monthly average concentrations.  For information about allowable exceedances and targets, and the limitations of data shown, see the factsheet on monitoring air quality in New Zealand. 

    The concentrations depend on local sources of emissions and weather conditions. 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 go 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.  At some monitoring sites, the hourly temperature and wind data are available to explore the relationship between local weather conditions and PM10 concentrations.  See this factsheet about why air quality is important and factors that influence air quality.

    What is this graph showing me?

    This graph shows how concentrations of nitrogen dioxide change on an hourly, daily, monthly or annual basis for the selected time period.  The number of exceedance hours can be viewed over the last 10 years or all years if available. 

    The nitrogen dioxide hourly average concentrations and exceedances are compared to the National Standard (NES-AQ). The nitrogen dioxide daily and annual average concentrations are compared to the WHO guidelines.  The standard and guideline limits are denoted by the red horizontal line. There is no guideline for monthly average concentrations.  For information about allowable exceedances and targets, and the limitations of data shown, see the factsheet on monitoring air quality in New Zealand. 

    The concentrations depend on local sources of emissions and weather conditions. Emissions from various sources change, depending on whether it's a weekday or the weekend or at different times of the year.  Still conditions often lead to high concentrations, as there is no wind to blow away the pollutants in the air.  At some monitoring sites, the hourly temperature and wind data are available to explore the relationship between local weather conditions and nitrogen dioxide concentrations.  See this factsheet about why air quality is important and factors that influence air quality.

    What is this graph showing me?

    This graph shows how concentrations of carbon monoxide change on an hourly, daily, monthly or annual basis for the selected time period. 

    The carbon monoxide hourly and daily concentrations are compared to WHO guidelines. The guideline limits are denoted by the red horizontal line.  There are no guidelines for monthly or annual average data. The NES-AQ is for an eight-hour average carbon monoxide concentration of 10 mg/m3, not shown here.  For information about allowable exceedances and targets, and the limitations of data shown, see the factsheet on monitoring air quality in New Zealand. 

    The concentrations depend on local sources of emissions and what the weather is.  Emissions from various sources change, depending on whether it’s a weekday or the weekend or at different times of the year. Still conditions often lead to high concentrations, as there is no wind to blow away the pollutants in the air. At some monitoring sites, the hourly temperature and wind data are available to explore the relationship between local weather conditions and carbon monoxide concentrations.  See this factsheet about why air quality is important and factors that influence air quality.
