US "Very Concerned" About Religious Freedom in India: Trump Admin Official

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, Feb 1: Activist Sharjeel Imam's mobile phone and laptop along with some anti-CAA posters have been seized from his house in Bihar's Jehanabad and rented flat in Vasant Kunj, police said on Friday.

Imam was arrested by the Delhi Police's Crime Branch from Jehanabad in a sedition case and he is being questioned by police for his alleged inflammatory speeches in Aligarh and at the Jamia Millia Islamia University here.

During investigation, a laptop and a desktop belonging to Imam were recovered from his rented flat at Vasant Kunj, Deputy Commissioner of Police (Crime) Rajesh Deo said.

His mobile phone was recovered from his house at his native place in Jehanabad's Kako area on the instance of his brother, he said.

Imam had prepared anti-CAA and anti-NRC pamphlets with "misleading and intimidating facts" and then distributed them in various mosques, the copy of which have been recovered, police said.

The shop from where he made photocopies of the pamphlets has also been identified, they added.

Imam was arrested on Tuesday. He was brought to Delhi on Wednesday and produced at the residence of Chief Metropolitan Magistrate Purushottam Pathak in the evening amid tight security after which police were granted his five-day custody.

The PhD scholar at the Jawaharlal Nehru University's Centre for Historical Studies has been booked for sedition and other charges in several states after videos of his alleged inflammatory speeches, made during protests against the Citizenship (Amendment) Act (CAA), were circulated on the social media.

An FIR was registered against Imam by the Delhi Police on January 25 under IPC sections 124A (sedition) and 153A (promoting or attempting to promote disharmony or feelings of enmity on grounds of religion, race, place of birth, residence, language, caste or community or any other ground whatsoever) among others.

New Delhi, Apr 10: With 896 COVID-19 cases reported in the country in the last 24 hours, India's total number of coronavirus positive cases rose to 6,761 on Friday, informed the Union Ministry of Health and Family Welfare.

Out of all these cases, 6039 are active cases, 516 have been cured/discharged/ migrated, and 206 deaths have been reported so far.

The country witnessed the highest one day increase with 896 cases.

37 deaths were reported in the last 24 hours.

Maharashtra with 1364 cases is the worst affected state followed by the Union Territory of Delhi with 898 cases and Tamil Nadu with 834 cases.

The country is under a 21-day lockdown until April 14 which was imposed to curb the spread of the virus.

States like Odisha and Punjab have extended the lockdown till April 30.
