Plunket AQ

Richmond is the largest urban area within Tasman District. It is located on the Waimea Plain adjoining Tasman Bay and Nelson City.

It has one monitoring site of PM10 and PM2.5.

Richmond has one air quality monitoring site located between commercial and residential land uses. The main state highway runs to the north west.

Air Quality Monitoring for Richmond began in 2000 with the current site established in 2006 when continuous monitoring of PM10 commenced. Monitoring of PM2.5 began at the site in October 2015 as daily measurements before changing to continuous monitoring in October 2018. From January 2021 both PM10 and PM2.5 are measured by a Thermo 5028i Beta Attenuation Monitor (BAM). All continuous monitoring is periodically benchmarked to measurements from a Thermo Partisol Monitor to maintain consistency of the dataset over time. The last time benchmarking occurred was during 2020.

A meteorological monitoring station is located approximately 370 meters to the south east and a second meteorological monitoring site approximately 1350 meters to the north.

Scientific Indicators
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.
