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, Jan 7: Facing criticism from social media and political quarters for holding a 'Free Kashmir' poster during a protest against violence at Jawaharlal Nehru University (JNU), Mehak Prabhu, a Mumbai-based storyteller, on Tuesday clarified that she meant to highlight the restrictions imposed in Jammu and Kashmir and wishes to see peace in the region, adding she had no other motive behind her actions.

"At around 7 pm yesterday, I reached where the protest was happening at the Gateway of India. Like anybody else who believes in democracy, I also joined that protest. We were standing for justice to the JNU students," Prabhu said in a video posted on Facebook.

"I saw a bunch of people who were painting placards on every issue like NRC, CAA and for JNU students. There was a placard lying on the side which said 'Free Kashmir'. The first thing which came to my mind when I saw that placard was about the basic constitutional rights of Kashmiris," she said.

Prabhu also said that she was not a Kashmiri and was brought up in Mumbai. She outlined that she was standing with a flower in her hand and asserted that the entire matter was "completely blown out of proportion".

"I was quietly standing with a flower in my hand. This means we need to make peace together. That was my only intention in holding that placard. The narrative that has been put out is absolutely wrong," she said, describing the reactions to the matter was "crazy".

The Mumbai-based storyteller underlined that the incident is scary and urged the people to spread the words of what she said and not hatred.

"The way it has gone, it is very scary. I am a simple person. As a woman, it is very scary for my safety right now. Spread this side of my story and let's stop it here. Let us not spread the hate. It has happened to me, it can happen to anyone. We should not live in fear," Prabhu further said.

Chennai, Jun 10: DMK MLA J Anbazhagan who had tested positive for coronavirus and was on ventilator support from June 3 passed away at a hospital in Chennai on Wednesday.

Coincidently, today is the 62nd birthday of the MLA.

"Anbazhagan J, who has been fighting for his life with severe COVID 19 pneumonia rapidly deteriorated early this morning. In spite of full medical support including mechanical ventilation at our COVID facility, he succumbed to his illness. He was declared dead at 08:05 hours on the 10th of June 2020," the hospital said in a statement.

In 2001, Anbazhagan was elected from T Nagar Assembly constituency. He served for five years.

Later in 2011, he was elected to Tamil Nadu Assembly from Chepauk-Thiruvallikeni seat. The DMK leader was re-elected from the same constituency in 2016.
