Ex-Armyman Naresh randomly kills 6 innocent Indians in 1 hour

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.

Guwahati, Jan 26: Four powerful grenade explosions--three in Dibrugarh and one in Charaideo districts--rocked Assam Sunday morning as the country celebrated Republic Day, police said.

In Dibrugarh district, an explosion took place at Graham Bazar and another beside a gurudwara on A T Road, both under Dibrugarh police station.

Another explosion rocked the oil town of Duliajan whose details are still awaited, police said.

Another explosion rocked Teok Ghat under Sonari police station of Charaideo district, they said.

Senior officials have rushed to the explosion sites and details of casualty are awaited, police added.

New Delhi, Feb 3: The Allahabad High Court on Monday granted bail to former BJP leader Swami Chinmayanand in the alleged rape case of a law student. He was arrested in September last year after the 23-year-old woman accused him of sexual harassment and blackmail.

The woman was a student of the Chinmayanand-controlled SS Law College in Shahjahanpur in Uttar Pradesh.

Chinmayanand is facing charges under Sections 376C (sexual intercourse by a person or persons taking advantage of their official position), 354 D (stalking), 342 (wrongful confinement) and 506 (criminal intimidation) of the Indian Penal Code (IPC).

The case is being investigated by a Special Investigation Team (SIT) formed on the directions of the Supreme Court.

The case came to light after the woman posted a video on August 23 last year on social media alleging that “a senior leader of the saint community” was harassing and threatening to kill her. The law student went missing a day later, after which her father lodged a complaint, accusing Chinmayanand of harassing his daughter.

Chinmayanand was expelled from the BJP after his arrest.

The SIT had, on November 6, submitted chargesheet in the case.

In a parallel case, the woman was charged with trying to extort money from Chinmayanad. The Allahabad High Court granted her bail in that case in December last year.
