Delhi Government to Conduct Fourth Cloud Seeding Trial on Thursday, Conditions Permit

Strategic Insights -

The Delhi government, in its efforts to combat air pollution, plans to conduct a fourth trial of cloud seeding on Thursday, contingent upon moisture content above 30%. The decision comes after two planned trials for Wednesday were abandoned due to low moisture levels. This development follows the recent cloud seeding pilot operation, which was executed in partnership with IIT Kanpur and aimed at reducing particulate matter (PM) in select areas of the city.

Key Takeaways:

  • The Delhi government will conduct a fourth trial of cloud seeding on Thursday, provided moisture content is above 30%.
  • The recent cloud seeding pilot operation, in partnership with IIT Kanpur, recorded reductions in PM10 as high as 41.9% along with significant AQI improvements.
  • IIT Kanpur reported a reduction of 610% in PM2.5 and PM10 concentrations in real-time data.
  • Three previous trials of cloud seeding were conducted, but none resulted in rain activity in Delhi due to low moisture levels.
  • At least 50% moisture is required for cloud seeding, but the trials conducted so far had moisture levels below 20%.
  • Officials are in touch with the IMD for updates and plan to conduct the next trial once conditions permit.
  • The Delhi government combines technology with civic engagement and enforcement to achieve improved air quality.
  • IIT Kanpur stated that even under limited moisture conditions, cloud seeding can contribute to improved air quality.

Statistics:

  • Moisture content needed for cloud seeding: at least 50%
  • Moisture content during previous trials: less than 20%
  • Reduction in PM10: up to 41.9%
  • Reduction in PM2.5 and PM10 concentrations: 610%
  • Number of cloud seeding trials conducted so far: 3
  • Date of the first cloud seeding trial: October 23
  • Date when two more cloud seeding trials were conducted: Tuesday
  • Percentage of parts per million (ppm) of particulate matter reduced: not specified
  • Air Quality Index (AQI) improvements: significant
