The COVID lockdown in India provided a unique opportunity to study anthropogenic emissions under relatively cleaner conditions. This study reports an episodic event characterized by rapid growth and high hygroscopicity of new aerosol particles formed in the SO2 plume from a large coal-fired power plant. These sulfate-rich particles exhibited high cloud-forming potential, offering insights into the contributions of different anthropogenic emission sectors to climate forcing.
