Grey Road

This was the main monitoring site for Timaru city from 1997 to early 2006. The site had to be moved when the Timaru Main School was closed, as it was located in the school's grounds. A new site was established in Anzac Square in April 2006.  A comparison of PM10 measured at both sites in 2006 is shown when you click Read more +.

Out of the contaminants measured at this site only PM10 has exceeded guidelines. Concentrations of carbon monoxide, sulphur dioxide and nitrogen dioxide have been lower than guidelines when measured. Only monthly and annual averages for all years can be seen in the graphs below. Nitrogen dioxide was monitored between July and December 2005.

    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).

    What do the dashboard colours mean for carbon monoxide?

    The dashboard colours show how carbon monoxide levels sit in relation to the guideline – from green (less than 10%) to red (over the guideline).  The guideline (100% value) for the hourly average carbon monoxide is 30 mg/m3.  There are no guidelines for daily, monthly or annual data (charcoal colour).
