New statistical method to detect ozone pollution hot spots and monitor instrument failure; combining PCA and MEWMA

Green Car Congress

NOVEMBER 13, 2016

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. Ozone is the reactive form of oxygen that contains three atoms per molecule (O 3 ) rather than the normal two. Khadraoui, S. &

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

Scaling of industry sales statistics enabled the discrepancy to be attributed to the use of ancillary solvent products such as screenwash and deicer which are not included in internationally applied vehicle emission methodologies. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

The largest sources of air pollution are not industry and transport but small domestic fires and agriculture. In the EU exposure to fine particles and ozone claims 180,000 lives a year, including 35,000 in Germany. Other major sources are fossil-fuel fired power plants, industry, biomass combustion and motor vehicles.
