Awatoto AQ

Monitoring at Awatoto began in 2012. Air quality is reduced by industrial or rural activities as well as from natural sources (salt spray).

The Awatoto monitor has been at its present location in Waitangi Road since February 2012. It is a small, localised airshed where land use includes industry (manufacturing and processing) and rural activities. In contrast to the urban areas, at Awatoto it is windy weather that increases PM10 concentrations and the airshed receives a high level of PM10 from natural sources such as wind-blown soil/dust and sea spray. Awatoto is limited to no more than one exceedance of the NES in a year.

Note: On two occasions when concentrations exceeded the NES (11/6/2014 & 1/10/2014), these were considered to result from high sea salt levels in stormy conditions and have been recognised as ‘exceptional events’ by the Minister for the Environment.

    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.
