Urban air quality issues have emerged as a major concern impacting quality of life. India is ranked as one of the worlds’ most polluted countries, with 14 cities in the top 20 most polluted cities globally, according to the 2018 Global Ambient Air Quality Database of the World Health Organisation. An Air Quality Index is defined as an overall scheme that transforms weighted values of individual air pollution related parameters into a single number or set of numbers. Air quality indicates the state of air around us. Like the weather, air quality can change from day to day or even hour to hour. Air Quality Index of Mumbai and Pune City is considered for the present research. The Paper attempts to analyze the variations in air quality Index in year 2018. The average RSPM concentration was 87.8 μg/m3 at Karve road Pune and 128.49μg/m3 at Sion, Mumbai in 2018.Both Cities have significant variations in topographical and meteorological factors. The observation and analysis reflects that the Mumbai city has higher concentration of NOx and RSPM as compared to Pune during the year 2018. According to the, Central Pollution Control Board, PM 10 and PM 2.5 levels in Mumbai have been steadily increasing.
