As People Stay Home, Air Pollution In North India At 20-Year Low: NASA

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.

New Delhi, Jan 15: Suspended Deputy Superintendent of J&K Police Davinder Singh had ferried Hizbul Mujahideen terrorist Naveed Babu to Jammu last year also and facilitated his return to Shopian after "rest and recuperation", officials interrogating him said here Tuesday.

"Meri mati maari gayi thi (I must have lost my mind to do what I did)," an interrogator quoted Singh as saying after the DSP failed to impress them with his theory of catching a big terrorist.

Singh was arrested last Saturday along with Naveed Babu alias Babar Azam, a resident of Nazneenpora in South Kashmir's Shopian district, and his associate Asif Ahmad.

He is believed to have taken Rs 12 lakh for smuggling the two to Chandigarh for providing them accommodation for a couple of months, officials said. The officials, who have been spending considerable time questioning Singh, said there have been many inconsistencies in his statements and everything was being crosschecked and corroborated with the confessions of captured militants who have been kept in different rooms at an interrogation centre in South Kashmir.

During questioning it emerged that Singh had taken them to Jammu in 2019 also, the officials said.

In a tone laced with sarcasm, they said the DSP was taking the militants for "rest and recuperation".

Naveed told the interrogators that they used to stay in the hilly regions to avoid the J&K police and left the areas to escape harsh winters, they said.

The official said the DSP's bank accounts and other assets were being verified by the police and papers were being collected, amid speculations that the case may be handed over to the National Investigation Agency (NIA).

Going into the service history of Singh, majority of retired and serving officials of the JKP spoken to referred to a proverb -- coming events cast their shadows long before -- to say that if action had been taken against the officer during his probation period, such things would not have happened.

Recruited in 1990 as a sub-inspector, Singh along with another probationary officer were subject of an internal enquiry where some narcotics had been seized from a truck. However, the contraband was sold by Singh and another sub-inspector, the officials recalled.

There was a move to dismiss them from the service which was stalled by an Inspector General rank officer purely on humanitarian ground and the duo was shifted to the Special Operations Group, a team of policemen engaged in counter-militancy offensive.

However, he could not last there for long and was shifted this time to the police lines only to be rehabilitated in 1997 again in the SOG.

During this period, he was posted in Budgam and is alleged to have indulged in extortion for which he was sent back to the police lines.

His proper rehabilitation began in 2015 by the then Director General of Police K Rajendra, who posted him in district headquarters of Shopian and Pulwama, the officials said.

However, after some alleged wrongdoing during his stint in Pulwama, the then Director General of Police S P Vaid transferred him in August 2018 to the sensitive Anti-Hijacking Unit in Srinagar, though the move was opposed by some other officers.

An advocate, Irfan Ahmad Mir, was driving the vehicle when they were caught by the police on National Highway in Kulgam district.

The advocate, who has also been arrested, had travelled to Pakistan five times on an Indian passport.

New Delhi, May 19: In a fresh blow to saffronite journalist Arnab Goswami, the Supreme Court of India today rejected his plea seeking transfer of the investigation of a case, filed against him for defaming Congress interim president Sonia Gandhi, to the CBI. The court also refused to quash the FIRs filed against him.

Goswami, editor-in-chief of Republic TV, has been booked in connection with a TV show on the gathering of migrants outside Bandra railway station on April 14. This apart, multiple FIRs have been filed against him for his show on Palghar lynching. In that show, he had posed certain questions on the incident to Congress President Sonia Gandhi, following which Congress workers lodged complaints against him in various states.

Extending Goswami’s interim protection from arrest by three weeks, the Supreme Court said, “Right of a journalist under 19 1 (a) higher…Free citizens can’t exist if news media can’t speak.”

During the earlier hearing, Senior Advocate Harish Salve, appearing for Goswami, had urged the court to transfer the probe to an agency like CBI. He said the “nature of the” second FIR against Goswami over a show on the migrant gathering outside Bandra station on April 14 “shows that it’s arm-twisting tactic”. 

“They are trying to stifle an unpleasant voice. This is a political party targeting a journalist. All complainants are members of one political party. They have a problem with the government. They want to teach this journalist a lesson,” he added.

Objecting to Salve’s plea to transfer the case to the CBI, Maharashtra government counsel, Senior Advocate Kapil Sibal, had said, “CBI investigation will go into your hands”. 

Sibal denied that Goswami was being harassed and said he was only asked relevant questions. He said Goswami should “stop this communal violence and communal mongering”.

New Delhi, Aug 3: Congress leader and Rajya Sabha MP Digvijaya Singh on Monday said that Prime Minister Narendra Modi should defer the foundation stone laying ceremony for Ram temple from August 5 as it will be an "inauspicious hour" for the event.

"I request Modi Ji again that the inauspicious occasion of August 5 (for foundation stone laying ceremony for Ram temple) should be deferred. The construction of Ram temple is to begin after hundreds of years of struggle and PM Modi should leave his stubbornness that may cause an obstruction in the process," Digvijaya tweeted (translated from Hindi).

The Congress leader went on to claim that several BJP leaders were falling sick due to COVID-19 as the result of ignoring the norms of Sanatan Dharma. "The results of ignoring the norms of Sanatan Dharma are - all priests of Ram temple tested positive for COVID-19, death of UP Minister Kamal Rani Varun due to corona, UP BJP chief tested COVID-19 positive, Home Minister Amit Shah tested positive for COVID-19, Madhya Pradesh CM Shivraj Singh Chouhan tested positive for COVID-19, Karnataka CM Yediyurappa tested positive for COVID-19," he added.

"Lord Ram is the epicentre of faith for crores of Hindus and the PM should not play with norms and traditions of Sanatan Dharma established across thousands of years," he added.

The Congress leader further questioned the urgency of holding the foundation stone laying event in times when COVID-19 spread is prevalent across the country.

"By laying the foundation stone for Ram temple at an inauspicious hour, how many people do you want to send to the hospital Modi Ji? Yogi Ji, please explain to Modi Ji. In your presence, why are the norms and traditions of Sanatan Dharma being broken? What is your compulsion that you are allowing this to happen?" he contended.

"One more question arises. A minister of the Uttar Pradesh government died due to coronavirus. Union Home Minister tested positive for COVID-19 and Uttar Pradesh BJP chief also tested positive. In these circumstances, whether Uttar Pradesh Chief Minister and India's Prime Minister should not be quarantined? Is being quarantined only mandated for common people? Not for Prime Minister and Chief Ministers? The time limit for quarantine is 14 days," he added.

He further said that the entire cabinet should go into quarantine otherwise they will infect the residents of Ayodhya.

"These people's religion is 'Hindutva' and not 'Sanatan Dharma'. hence they have nothing to do with Sanatan Dharma's traditions. They have broken all the norms. Now, Modi Ji will issue the muhurta and he will only lay the foundation stone," he tweeted.

The Prime Minister is scheduled to lay the foundation stone of the Ram temple in Ayodhya on August 5.

The construction of Ram temple will begin after the ceremony to lay the foundation stone in which Chief Ministers of several states, Ministers from the Union Cabinet and RSS chief Mohan Bhagwat are also likely to participate.
