The ongoing COVID-19 pandemic led to a worldwide reduction in aerosol emissions. Anecdotal effects on air quality and visibility were widely reported. Less known are the impacts on the planetary energy balance, and by extension, on weather and climate. By separating the impacts from meteorology and emissions with model simulations, the authors, led by AOS Faculty Member Yi Ming, a GFDL senior scientist, found that about one‐third of the clear‐sky anomalies can be attributed to pandemic‐related emission reductions, and the rest to weather variability and long‐term emission trends.
