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.

Feb 26: In a midnight hearing, the Delhi High Court directed police to ensure safe passage to government hospitals and emergency treatment for those injured in the communal violence erupted in northeast Delhi over the amended citizenship law.

The court held a special hearing, which started at 12:30 am, at the residence of Justice S Muralidhar after receiving a call from an advocate explaining the dire circumstances under which the victims were unable to be removed from a small hospital to the GTB Hospital.

A bench of Justices S Muralidhar and Anup J Bhambhani directed the Delhi Police to ensure safe passage of the injured victims by deploying all resources at its command and on the strength of this order as well as to make sure they receive immediate emergency treatment if not at the Guru Teg Bahadur Hospital then at the Lok Nayak Jai Prakash Narayan Hospital (LNJP) or Maulana Azad or any other hospital.

The bench also called for a status report of compliance, including information about the injured victims and the treatment offered to them, and the matter will be heard during the day at 2:15 pm.

It said the order be communicated to the medical superintendents of the GTB and the LNJP Hospitals.

The urgent hearing was conducted after advocate Suroor Mander called the judge and sought urgent orders for safe passage of ambulances for the injured.

The Delhi Police and the government were represented through additional standing counsel Sanjoy Ghose.

During the hearing, the bench spoke over phone to doctor Anwar of the Al-hind Hospital in New Mustafabad who told the court that there were two bodies and 22 injured persons there and he had been trying to seek police assistance since 4 pm on Tuesday without success.

The court then directed the senior officials to reach to the hospital forthwith, following which they started the process of evacuating the injured to the nearest hospitals.

It also said this order be brought to the knowledge of the Delhi Police Commissioner.

Communal violence over the amended citizenship law in northeast Delhi claimed at least 18 lives till Wednesday.

On Tuesday, the violence escalated in northeast Delhi as police struggled to check the rioters who ran amok on streets, burning and looting shops, pelting stones and thrashing people.

New Delhi, Jan 22: Delhi Chief Minister Arvind Kejriwal has assets worth Rs 3.4 crore, an increase of Rs 1.3 crore from 2015, according to his election affidavit.

Kejriwal's total assets were worth Rs 2.1 crore in 2015.

The cash and fixed deposits of Kejriwal's wife Sunita Kejriwal increased from Rs 15 lakh in 2015 to Rs 57 lakh in 2020.

A party functionary said Rs 32 lakh worth cash and fixed deposits have been received by Sunita Kejriwal as voluntary retirement benefits while the rest are savings.

The cash and fixed deposits of the chief minister increased from Rs 2.26 lakh in 2015 to Rs 9.65 lakh in 2020.

There was no change in the value of immovable assets of his wife while Kejriwal's immovable assets' worth increased from Rs 92 lakh to Rs 177 lakh.

The party functionaries said increase in Kejriwal's immovable assets' worth is due to the increased valuation of the same asset as in 2015.
