 The study investigates the impact of reduced aerosol and gases pollution loadings on the Indian summer monsoon, ISM, due to lockdown measures imposed during the Covid-19 pandemic. It shows that the decrease in anthropogenic emissions led to an increase in surface solar radiation, strengthening of the ISM, changes in atmospheric circulation, and accumulation of dust over the Tibetan Plateau, resulting in enhanced rainfall over India. The study emphasises the need for stringent measures to limit future anthropogenic emissions in South Asia for protecting the region's water resources.
