Northfield Station (Gaseous data) - 2015 to 2019
This data set contains validated gaseous pollution data for the years 2015 to 2019 for the North eastern Adelaide region in monthly files. Data was collected as 1 hour averages. Information provided is Ozone values expressed in parts per million (ppm), Nitrogen oxides values expressed in parts per million (ppm), Sulfur dioxide values expressed in parts per million (ppm). Time expressed as Time Ending Averages.
Negative values occur from time to time and are a result of the extremely low concentration levels and the noise of the instrument. Sampling methods, standards and uncertainties: Ozone (O3) Ultraviolet Absorbance (UVA), AS3580.6.1 – 1993, U95= ±0.005 ppm @ 0.100 ppm.
Nitrogen oxides (NO, NO2, NOx) Chemiluminescence, AS3580.5.1 – 1993, U95= ±0.050 ppm @ 0.400 ppm.
Sulfur dioxide (SO2) Ultraviolet Fluorescence (UVF), AS3580.4.1 – 1990, U95= ±0.011 ppm @ 0.200 ppm.
Carbon monoxide (CO) Gas Phase Correlation (GPC), AS3850.7.1 – 1992, U95= ±1.46 ppm @ 40 ppm.
Field labels: O3 UVA ppm – Ozone, NO Chemiluminescence ppm – Nitric oxide, NO2 calc Chemiluminescence ppm – Nitrogen dioxide calculated from NOx-NO, NOx Chemiluminescence ppm – Nitrogen oxides, SO2 UVF ppm – Sulfur dioxide, CO GPC ppm – Carbon monoxide.
For comparison to National Environment Protection (Ambient Air Quality) Measure (NEPM) standards, any average calculated from this data is only valid if it is based on at least 75% of the expected samples in the averaging period. This applies to all averaging periods. Further information on data availability and computing averages can be found in the National Environment Protection (Ambient Air Quality) Measure Technical paper No. 5 – Data Collection and Handling.
