A Comprehensive Review on Recent Advances in Observation and Estimation of Nitrogen Oxide (NOx) Emissions

The rapid rise in urbanization and industrialization has adverse effects on air pollution and the emission of Nitrogen Oxide NO
x
into the atmosphere. For effective mitigation of pollution, it is necessary to understand the impact of various NO
x
sources on the air quality. The article examines the recent advances in NO
x
emission measurements using satellite-based computer-aided models. Additionally, this article also explores several investigative studies evaluating the distinct aspects of NO
x
emissions. This comprehensive study also examines the temporal and spatial variations in NO
x
emissions, inspects the use of satellite data for assessing emissions, and explores the impact of meteorological conditions on NO
x
levels. This research is conducted in various regions like China, India, Europe, and the Middle East demonstrating the scope of this study worldwide. This review article aims to provide a comprehensive interpretation of monitoring NO
x
emissions from space and assessing their implications on air quality and environmental regulations. The synthesis of findings from this review using various scholarly articles will be used to provide a comprehensive overview of the current NO
x
emission situation.
