Air Pollution: Short-Lived Climate-Forced Ozone in Urban Areas of Kolkata

Abstract

The rapid growth in the economy as well as urban population brings us challenges to the venture of maintaining the clean urban air. Urban air quality is a cause of public concern, largely as a result of increased instances of smog and health problems. New pollutants are being increasingly recognised and point to sources, which are of inevitable use in day-to-day modern life. Air pollution sources have grown and so the pollutants. Many of these sources are indices of development. As ubiquitous components in the atmosphere, non-methane volatile organic compounds have received immense attention due to not only their adverse health effects on humans but also because of their role as the precursor of lower tropospheric ozone which eventually leads to urban photochemical smog. Modern studies on atmospheric photochemistry indicate that ozone mixing ratios at ambient air depend on complex, non-linear, feedback control processes involving NOx and VOC precursor mixing ratio. Hence, control computation is required, adopting mathematical models that include the best representation of the non-linear chemistry as the basis.
