In an interview with PTI, Agrawal, whose crew led the latest cloud-seeding trials in Delhi, stated whereas the 2 makes an attempt didn't result in synthetic rain, they supplied worthwhile information and scientific insights for future operations.
“It helps us perceive the connection between the quantity of seeding materials used, the moisture content material of clouds, and their ground-level affect. This may assist us fine-tune future operations,” he stated.
Agrawal defined that the train was paused as a consequence of low moisture content material in clouds, making situations unsuitable for efficient seeding.
“We'd like at the very least 30 to 50 per cent cloud moisture. Since that was not accessible, we determined to attend till situations enhance,” he stated, including the trials will resume as soon as beneficial climate returns.
Dispelling fears about environmental or well being hazards, Agrawal stated the combination sprayed into clouds primarily accommodates frequent salt and a small quantity of silver iodide.”We use lower than one kilogram of silver iodide over 100 sq. kilometres — lower than 10 grams per sq. kilometre. That is too little to have any dangerous impact on people, animals or vegetation,” he stated.Agrawal acknowledged that cloud seeding can't be a everlasting resolution to air air pollution.
“It's an SOS measure, one thing that can be utilized solely when air pollution ranges are very excessive and appropriate clouds can be found. The true resolution lies in lowering emissions and controlling air pollution on the supply,” Agrawal stated.
Environmentalists have expressed considerations concerning the potential accumulation of silver iodide in soil and water, which might have an effect on crops, aquatic life, and consuming water high quality.
Agrawal maintained that the concentrations used are negligible and don't pose ecological dangers.
Highlighting the innovation behind the trouble, Agrawal stated the know-how, together with the flares and seeding materials, has been developed indigenously at IIT-Kanpur, marking a ‘Make in India' milestone.
The institute had earlier performed profitable trials in Kanpur in 2017-18, however that is the primary such experiment within the Delhi-NCR area, he added.
The Delhi authorities performed two cloud-seeding trials in Burari, north Karol Bagh, and Mayur Vihar on Tuesday in collaboration with IIT-Kanpur, however there was no rain.
