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. Minimal rainfall was recorded in Noida and Better Noida after the trials.
“The trial was performed over an space of 300 sq. kilometres. The general value of that, in my tough estimate, got here to round Rs 60 lakh. It roughly involves round Rs 20,000 per sq. kilometre.
“If we conduct the train over an space of 1,000 sq. kilometres, the price could be round Rs 2 crore,” Agrawal defined in a video assertion.
Delving into additional particulars, he mentioned whether it is performed over your complete winter interval, and it's assumed that clouds are current as soon as in 10 days, the price would come to round Rs 25 to Rs 30 crore.
“That, within the total scheme of issues, shouldn't be a really great amount. The sum of money spent on air pollution management in Delhi is sort of giant,” the IIT-Kanpur director mentioned.He asserted that within the absence of quite a lot of cloud moisture, the opportunity of inducing rainfall acquired lowered.”It (moisture content material) was solely round 15 per cent. With that low moisture content material, the opportunity of making rain may be very low. We didn't obtain success from that perspective, however we acquired quite a lot of helpful info.
“We arrange 15 stations at numerous areas to measure air air pollution and moisture ranges. There was some discount in PM 2.5 and PM 10 concentrations. Even with a low stage of moisture, seeding does have some influence, albeit not the identical that one would ideally prefer to see,” he mentioned.
As a part of trials, a finely floor combination of widespread salt, rock salt and silver iodide was injected into clouds to induce rain.
Round every tiny particle, water begins condensing, he mentioned, including that when there's condensation, water droplets kind. As soon as the droplets are in a ample quantity, rain happens, Agrawal mentioned.
A cloud-seeding trial scheduled for Wednesday in Delhi was placed on maintain resulting from inadequate moisture within the clouds.
