Locations for analysis

For the analysis following cities are picked:

• Aligarh

• Bengaluru

• Gurgaon

• Mohali

Reason for picking the above location

• Aligarh is my hometown and is also known as City of Locks. Having a numerous large scale manufacturing units in this city, will like to study the how lockdown really impacted the air quality in this city.

• Bengaluru is known as Silicon Valley of India and most of the tech companies has their headquarter in this city. This city is also known as most traffic-congested city.

• Gurgaon is the second largest IT Hub of India and is home to the many startups. Apart from IT it is also home to huge manufacturing units like Maruti Suzuki.

• Mohali is the place where I spent most of the time from the beginning of 2019. This city is closed to the hilly areas and most of the part is covered by trees.
