Corona virus was first observed in Wuhan City of China in the end of the year 2019. In less than 3 months of its appearance, it turned out to be a global pandemic. The virus has affected more than 4.3 million of people across the globe till midmonth of May 2020. As a protective measure, many countries have enforced lockdown, which certainly reflected some beneficial effects on Nature. Lesser human-induced pollution has introduced us to a whole new healthy environment. This study is based on the observations of AOD (Aerosol Optical Depth) from the satellite Himawari-8. This study will also include the observation of tropospheric level of NO2 with the help of an instrument Aura-OMI over the region of southeast Asia (SEA). This study also focuses on measurements at ground level across several stations of Malaysia, to check the changes in level of aerosol and air pollutants caused by this lockdown. This lockdown has caused a considerable decrease in the level of AOD across Southeast Asia and also in the pollution current in oceans, a notable decrease of 27 percent to 30 percent of NO2 has also been observed in the troposphere. The respective amount of PM 10, PM 2.5, NO2, SO2, and CO has also decreased by 26–31%, 23– 32%, 63–64%, 9–20%, and 25–31%, in the region of Malaysia. Since, this reduction is favorable for our environment, it is also beneficial for one’s health, and thus, it has become an interesting field of research related to health and pollution.
