Expository Assessment of Air Quality Scenario with Sentinel-5 Precursor TROPOMI Explorer Sensor

Abstract

Air pollution is the atmospheric state in which specific elements concentrations has adverse impacts on human health as well as the environment including global warming, transportation, acidic rain, and ozone layer depletion. Nowadays, a large portion of the world's population lives in urban areas, where population growth and the increasing number of vehicles have significantly worsened air quality. Clean air is essential for the health and well-being of any region's environment and its inhabitants.

Henceforth, the primary focus of this research endeavour is to meticulously scrutinize the levels of key air pollutants, notably nitrogen dioxide (NO₂) and sulphur dioxide (SO₂), leveraging satellite remote sensing data obtained from TROPOMI EXPLORER across a network of monitoring stations dispersed throughout Lucknow City. Additionally, it aims to meticulously dissect ground-based air quality monitoring data to validate and amalgamate the observations derived from satellite technology. Furthermore, it analyses the distribution of concentrations of primary air pollutants, encompassing NO₂, SO₂, and PM₁₀, within Lucknow City, juxtaposing it against the stringent benchmarks stipulated by the World Health Organization (WHO) for air quality standards. Moreover, it endeavours to ascertain the deleterious health ramifications of air pollution by correlating air quality metrics with health outcomes among denizens of Lucknow City through a meticulously crafted questionnaire survey. The scrutiny of satellite imagery unveiled a conspicuous escalation in the concentration of air pollution parameters vis-à-vis the WHO's prescribed thresholds, portending consequential adverse ramifications for both the environment and human health.
