The experiment — Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX phase-4) — was a scientific investigation conducted in Solapur city.
The primary objective was to investigate the efficacy of hygroscopic seeding in deep convective clouds and to develop a cloud seeding protocol.
The study found that cloud seeding is an effective strategy for enhancing rainfall in a region under suitable conditions.
The seeded clouds produced more rainfall than the unseeded clouds.
It can help produce 18% more rainfall and partially address water requirements.
Calcium chloride flare was used for seeding the clouds.
The approximate cost of producing water through cloud seeding was 18 paisa per litre.
