No snooping on Rahul, it is 'transparent profiling': Jaitley

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 14: AAP convenor Arvind Kejriwal has invited Prime Minister Narendra Modi to his swearing-in ceremony scheduled to take place at the Ramlila Maidan on February 16, senior party leader Gopal Rai said on Friday.

Rai, the convenor of the Aam Aadmi Party's Delhi unit, said a letter was sent to the prime minister on Friday morning.

All seven Delhi MPs and eight newly-elected BJP MLAs have also been invited for the oath-taking ceremony, Rai told news agency.

No chief minister or political leaders from other states will be part of the event as it will be a "Delhi-specific" ceremony, Rai had said on Thursday.

Kejriwal, through front-page advertisements in newspapers, has urged Delhiites to attend his oath-taking ceremony as he is set to become the chief minister of Delhi for the third consecutive term.

Kejriwal will take oath as Delhi Chief minister along with his cabinet at Ramlila Maidan at 10 am on Sunday.

New Delhi, Feb 24: The shared values between India and the US are "discrimination, bigotry, and hostility towards refugees and asylum seekers", Amnesty International USA said in a joint statement with Amnesty International India ahead of US President Donald Trump's visit to India on Monday.

Trump, accompanied by his wife Melania, daughter Ivanka and son-in-law Jared Kushner as well as senior officials of his administration, landed in Ahmedabad on the first leg of his two-day visit to India.

"Anti-Muslim sentiment permeates the policies of both U.S. and Indian leaders. For decades, the U.S.-India relationship was anchored by claims of shared values of human rights and human dignity. Now, those shared values are discrimination, bigotry, and hostility towards refugees and asylum seekers,” Margaret Huang, Amnesty International USA’s executive director, was quoted as saying in the statement.

It was a reference to the anti-CAA protests in India, the internet lockdown in Jammu and Kashmir and the Muslim ban expansion by President Trump affecting Nigeria, Eritrea, Myanmar, Kyrgyzstan, Sudan and Tanzania, the statement said.

It added that Amnesty International USA’s researchers travelled to Lebanon and Jordan to conduct nearly 50 interviews with refugees that as a result of the previous version of the ban have been stranded in countries where they face restrictive policies, increasingly hostile environments, and lack the same rights as permanent residents or citizens.

The statement also came down hard on the Indian government, hitting out at the Citizenship (Amendment) Act (CAA) 2019 and saying it legitimises discrimination based on religious grounds.

It criticised statements such as “identify them (the protestors) by their clothes” or “shoot the traitors” by Prime Minister Modi and his party workers. Such remarks "peddled the narrative of fear and division that has fuelled further violence", it said.

“The internet and political lockdown in Kashmir has lasted for months and the enactment of CAA and the crackdown on protests has shown a leadership that is lacking empathy and a willingness to engage. We call on President Trump and Prime Minister Modi to work with the international community and address our concerns in their bilateral conversations,” Avinash Kumar, executive director, Amnesty International India said in the statement.
