Rs 389 crore dam collapses a day before inauguration

Mumbai, Mar 6: Harried Yes Bank depositors rushed to ATMs to withdraw cash but faced multitude of problems including closed down machines and long queues, after the RBI placed the bank under a moratorium, capping maximum withdrawals at Rs 50,000 per account for a month.

Aggravating the problems of depositors were difficulties accessing the internet banking channel, which ensured that they can't transfer the funds online as well. At an ATM in south Mumbai's Horniman Circle, with the RBI headquarters overlooking it, the shutters were pulled down.

The guard on duty said the machine was non-operational before he reported to work late in the evening and he was ordered to shut it after 2200 hrs. In the residential area of suburban Chembur, one ATM was dispensing cash but had a long queue of anxious depositors.

One man said it was still possible to withdraw up to Rs 50,000 in multiple transactions from the machine.

However, another machine nearby had run dry within minutes of the RBI announcement, a woman said.

The regulatory actions, undertaken by the RBI and the government, came hours after finance ministry sources confirmed that SBI was directed to bail out the troubled lender.

For the next month, Yes Bank will be led by the RBI-appointed administrator Prashant Kumar, an ex-chief financial officer of SBI.

New Delhi, Feb 28: The months of March, April and May are "likely to be warmer than normal" over northwest, west, central and parts of south India, the India Meteorological Department said today in its summer forecast.

Above normal heat wave conditions are also likely in the core heat wave (HW) zone during the season (March-May), the weather department said.

The core heat wave zone covers the states of Punjab, Himachal Pradesh, Delhi, Uttarakhand, Haryana, Rajasthan, Uttar Pradesh Gujarat, Madhya Pradesh, Bihar, Chhattisgarh, Jharkhand, West Bengal, Odisha and Telangana and parts of Maharashtra and coastal Andhra Pradesh.

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.
