abstract={The purpose of this study is to compare the Air Quality Index (AQI) in India before (1<SUP>st</SUP> January 2020 - 16<SUP>th</SUP> March 2020) and during the lockdown period (26<SUP>th</SUP> March 2020 - 4<SUP>th</SUP> June 2020). The AQI improved significantly throughout the lockdown resulted through spatio-temporal fluctuations based on Geographic Information System (GIS) mapping and multivariate statistical analysis using Correlation Matrix Analysis and Principal Component Analysis (PCA). The AQI declined by 34.51 percent in Northern India, 22.14 percent in Central India, 48.84 percent in Eastern India, 42.75 percent in Western India, 32.64 percent in Southern India, and 54.46 percent in Northeastern India during the lockdown. The findings would prompt the governments across the world to consider ways to reduce vehicle and industrial pollution to enhance air quality.},
