How much can artificial rain reduce pollution levels?

Question

Accepted Answer

Artificial Rain Can Reduce Pollution Levels by Up to 50 Percent

Artificial rain, induced through cloud seeding, has the potential to decrease pollution levels by as much as 50 percent. However, this reduction may be temporary, necessitating repeat applications as the underlying sources of pollution remain.
Cloud Seeding Process Aims to Increase Precipitation

The method involves introducing small chemical particles into clouds. These particles act as nuclei around which water droplets can form and coalesce, eventually developing into raindrops. Authorities in Delhi have initiated this process, with the Indian Institute of Technology in Kanpur spearheading the effort.
Potential for Rainfall and Effectiveness

According to a scientist at IIT-Kanpur, rainfall could occur between 15 minutes and four hours after the seeding process, with the quantity of rain being variable. While this technique has been used in other countries for agricultural purposes or to improve air quality, its effectiveness in reducing pollution is subject to scientific debate, with some studies showing mixed results.
Temporary Nature of Pollution Reduction

A key aspect of this intervention is its temporary impact on pollution. While rainfall can indeed wash pollutants from the air, the sources of pollution, such as vehicular emissions and industrial activity, are not eliminated. Therefore, as stated by an IIT-Kanpur scientist, the process may need to be repeated whenever suitable cloud cover is present to maintain reduced pollution levels.
