  Reduction of economic activities during the pandemic-related lockdown had resulted in decrease of air pollution in most parts of India, but satellite observations show that parts of central-western India and north India showed an increase in pollution in contrast to the general trend.   Scientists have identified that regions in the central-western part of India and north India are prone to higher air pollution exposure based on state-of-the-art satellite observations and hence are exposed to greater risk of respiratory problems. Multi-satellite remote sensing of air pollutants has evolved dramatically over the last decade. Synergic measurements of satellite and in-situ observation provide a more comprehensive understanding of air pollution episodes. In 2020, a complete nationwide lockdown was imposed over India to impede the spread of coronavirus disease. This enormously disrupted the economy with a single positive side effect, a short-term improvement in the air quali...
