Mobile air quality monitoring trailers

NIWA's mobile air quality monitoring trailers contain equipment capable of measuring a range of key air contaminants and meteorological parameters.

A basic mobile unit consists of a secure air-conditioned trailer complete with:

  • a 10-m telescopic mast with meteorological sensors for measuring wind speed, wind direction, air temperature, relative humidity, and solar radiation
  • data logging system linked to a local PC for data download and processing
  • modem and cell-phone for remote access
  • GPS for accurate positioning and tracking.

This set-up also allows it to be used as a general mobile laboratory. In addition, various high performance continuous air quality analysers are available and can be added as required to the system. These include instrumentation to measure:

  • fine particulate (PM10)
  • carbon monoxide (CO)
  • nitrogen oxides (NOX)
  • ozone (O3)
  • sulphur dioxide (SO2) and hydrogen sulphide (H2S).

Other equipment, such as an Aethalometer (for measuring Black Carbon or BC) and a Scanning Mobility Particle Sizer (SMPS), can also be incorporated.

As the mobile units are quick to install and can be configured for a range of user requirements, they are ideal for short-term investigations of local air quality issues.
