The study objective is to contemplate the effectiveness of COVID-19 on the pollution of Indian territory from January 2020 to April 2020. we've executed data from European Space Agency (ESA) and CPCB online portal for air quality data dissemination. The Sentinel – 5 P satellite images elucidate that the Air quality of Indian territory has been improved significantly during COVID-19. Mumbai and Delhi are among the foremost populated cities. These two cities have observed a considerable decrease in dioxide (40–50%) compared to an equivalent period last year. It suggests that the emergence of COVID-19 has been proved to a necessary evil as being advantageous for mitigating pollution on Indian territory during the lock-down. The study found a big decline in dioxide in reputed states of India, i.e., Delhi and Mumbai. Moreover, a faded track of dioxide is often seen at the Maritime route within the Indian Ocean. An upsurge within the environmental quality of India also will be beneficial for its neighbour countries, i.e., China, Pakistan, Iran, and Afghanistan.COVID-19 has not only breached the circle of the planet-wide economy but also stopped transportation throughout the world.

International and native transportation has been reduced, which lessens oil consumption and energy utilization. These variations have greatly influenced the environmental quality. National Aeronautics and Space Administration (NASA) and European Space Agency (ESA) reported that the extent of dioxide has imperatively diminished up to 30%, and there's a big improvement in environmental quality. NASA and ESA published images of various nations taken through its satellite to point the environmental quality before and after the COVID-19 lock-down. NASA utilized its Ozone Monitoring Instrument (OMI) through the AURA satellite, and ESA operated Tropospheric Monitoring Instrument (TROPOMI) through the Sentinel-5P satellite to gather this data.
