CAS students, mentored by faculty members, have prepared an exhaustive report (over three days during a hackathon) on 'cloud seeding.' The report critically examines whether cloud-seeding is a viable option for reducing air pollution, taking into account various scientific factors such as atmospheric stability, thermodynamic conditions, aerosol-cloud interaction, and washout and recovery rate.
