Exit Polls Delhi 2020: Arvind Kejriwal set to return as CM for a third time

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Mumbai, Mar 13:  Investor wealth worth nearly Rs 12 lakh crore was wiped out in less than 15 minutes of trading on the stock exchanges on Friday, with the two benchmarks, the BSE Sensex and the NSE Nifty, crashing over 10 per cent.

The 30-share BSE Sensex plummeted 3,380.59 points, or 10.31 per cent, to 29,397.55. It hit an intra-day low of 29,388.97, falling up to 3,389.17 points.

Trading was halted for 45 minutes in the early session after the index hit its lower circuit limit.

The BSE and NSE benchmark indices, however, pared most losses with the Sensex trading 835.40 points, or 2.55 per cent, lower at 31,942.74, and the Nifty was down 253.25 points or 2.64 per cent at 9,336.90 at 10.40 am.

The mayhem on Dalal Street eroded investor wealth worth Rs 12,92,479.88 crore, taking the total m-cap to Rs 1,12,78,172.75 crore on the BSE at 1020 hours.

The m-cap of BSE-listed companies stood at Rs 1,25,70,652.63 crore at the end of trading on Thursday.

Traders said besides global selloff, incessant foreign fund outflows also weighed on investor sentiments.

On a net basis, foreign institutional investors sold equities worth Rs 3,475.29 crore on Thursday, data available with stock exchanges showed.

On the BSE, 1,279 scrips declined, while 193 advanced and 40 remained unchanged.

Volatility heightened in global markets as benchmarks world over went into panic mode, insinuating a freakish selloff.

Bourses in Shanghai dropped over 3.32 per cent, Hong Kong 5.61 per cent, Seoul 7.58 per cent and Tokyo cracked up to 7.97 per cent.

Wall Street lost 10 per cent in overnight trade.

More than 1,30,000 cases of the novel coronavirus have been recorded in 116 countries and territories, killing at least 4,900 people.

The number of coronavirus patients in India has risen to 74, as per the health ministry.

Mumbai, Mar 5: Jet Airways founder Naresh Goyal and few others have been booked by the ED in a money laundering case even as the agency is conducting searches at his premises, officials said on Thursday.

They said a criminal case against the former chairman of the airlines has been filed under the Prevention of Money Laundering Act (PMLA) after taking cognisance of a recent Mumbai Police FIR filed against him.

The Enforcement Directorate carried out raids at Goyal's premises in Mumbai on Wednesday and also questioned him after filing the case, they said.

The action is continuing, they added.

The Mumbai Police FIR pertains to charges of alleged fraud by Goyal and others against a Mumbai-based travel company.

Goyal has earlier been grilled by the central probe agency in a case filed under the Foreign Exchange Management Act (FEMA) in September last year.

The agency had carried out similar raids, under the FEMA, in August last year against Goyal, his family and others.

ED has alleged in the past that the businessman's empire had 19 privately-held companies, five of which were registered abroad.

The agency is probing charges that these firms allegedly carried out “doubtful” transactions under the guise of selling, distribution and operating expenses.

The ED suspects that expenses at these companies were allegedly booked at fake and high costs and as a result, they “projected” huge losses.

Alleged shady aircraft lease transactions with non-existent offshore entities are also under the ED scanner and it is suspected that Jet Airways made payments for lease rental to “ghost firms”, which purportedly routed the ill-gotten money in Goyal's companies.

A full-service carrier, Jet Airways shut its operations in April last year after running out of cash.

A month earlier, Goyal had stepped down as the chairman of Jet Airways.
