      abstract     = {The high level of aerosol pollution in South Asia has a
                      measurable impact on clouds, radiation, and precipitation.
                      Here, exploring multiple observational data sets and
                      simulations of the state-of-the-art ECHAM6-HAMMOZ
                      chemistry-climate model, we report that the reduction in
                      anthropogenic emissions during the COVID-19 lockdown period
                      has enhanced precipitation by $5–25\%$ over India. This
                      precipitation enhancement is the result of the combined
                      effect of an enhancement in cloud cover, a reduction in
                      aerosol induced cloud invigoration and dynamical changes. We
                      observed that the increase in cloud cover was associated
                      with a reduction in cloud base height and an increase in the
                      effective radius of cloud particles which led to an increase
                      in cloud water content. In response to sudden emission
                      reduction, an anomalous northward moisture transport was
                      observed adding convection and precipitation over the Indian
                      region. Importantly, we show that there is an advantage of
                      anthropogenic pollution reduction for water availability in
                      addition to benefits of air quality, human health, and crop
