These states With Uttar Pradesh following close with 3 cities It is not surprising to see that these states are located in Northern India as it is known that the South has better air quality as compared to the North. Also, more monitoring devices are required to have adequate air quality data in a particular area, as most cities have limited monitoring stations in India which causes much of the pollution to go unreported. Furthermore, not all cities have equal monitoring stations. For example, Delhi has over 30 stations.
