Multi-channel DustTraks are used for stations reporting TSP, PM10 and PM2.5. Single-channel DustTraks are used for stations reporting TSP only. An ongoing upgrade is underway to replace all NSW sites with multi-channel instruments.
Most rural network stations use mid-cost indicative monitors which respond to all aerosols including dust, sea salt and smoke. Single-channel DustTraks (TSP only) will also respond to fog.
We have undertaken best efforts to ensure that data from these instruments is consistent with measurements from compliance instruments. However, note that instrument accuracy does not meet strict Australian Standards, therefore care must be taken in interpreting the data compared with Air NEPM standards without additional information. Reported data has only undergone preliminary automated checks, and further manual validation is performed for data stored in the DPIE database.
Data is reported in Australian Eastern Standard Time (AEST), and updates approximately 30 minutes past the hour (e.g. 11:00 values are online at approximately 11:30). However, during daylight saving, data is still collected and stored in AEST and will be presented with an apparent 90 minutes delay. Gaps indicate that a pollutant is not measured at the site OR instrument was offline OR that wireless or satellite connection was not able to be established with the site.
