New Delhi, Apr 6: Prime Minister Narendra Modi on Monday said India's efforts to combat coronavirus have set an example and it is among countries which understood the pandemic's seriousness and took various timely decisions to combat the virus.

Addressing BJP workers to mark the 40th foundation day of the party, he also appreciated the maturity shown by people during the lockdown, describing it as  unprecedented.

"We got to see our collective strength on Sunday evening," he said referring to the countrywide exercise to switch off lights and illuminate diyas for nine minutes to show India's collective strength to fight the deadly virus.

He also urged BJP workers to follow a five-point agenda, including working to ensure that no poor goes hungry.

He asked them to follow the guidelines issued by party president J P Nadda.

Fight against coronavirus is no less than war, Modi said, asking BJP workers to donate and encourage others to contribute to the PM-CARES fund.

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 7: A fringe right-wing group calling itself the Hindu Raksha Dal has purportedly taken responsibility for the attack on students of Jawaharlal Nehru University (JNU) in a video posted on social media.

The video, which was posted on social media on Monday and has gone viral since then, shows a man identifying himself as Pinki Chaudhary saying that those who resort  to “anti-national activities” will be treated in the same way that JNU students and faculty were.

He later told news channels that others involved in "anti-national activities" would face similar attacks.

There was no immediate reaction from the police on Chaudhury's claims.

“For several years, JNU has been a bastion of communists and we will not tolerate it. Hindu Raksha Dal, Bhupendra Tomar, Pinki Chaudhury take the responsibility of what has happened in JNU...all of them were our volunteers. Those who cannot do such work for Mother India don't have the right to live in this country,” Chaudhary is seen saying in the video.

“We are always ready to sacrifice our lives for Mother India. We will not tolerate anyone who speaks against the religion,” he added.

Efforts to reach the man were unsuccessful: his phone was switched off.

More than 35 students were injured Sunday when a masked mob went on the rampage, attacking students and professors and vandalising property. The JNUSU has accused the RSS-affiliated ABVP volunteers of attacking the students.
