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, Jun 28: Home Minister Amit Shah on Sunday targeted former Congress President Rahul Gandhi, saying he was indulging in "shallow-minded" politics and making statements that make Pakistan and China happy when soldiers are fighting a spirited battle.

Shah said the government is ready for a discussion in Parliament about the situation from 1962 (when India-China war took place) and it is sad that a former president of a party making statements, which are being celebrated in Pakistan and China.

The Home Minister's comments came during an interview with ANI when he was asked about Rahul's "Surrender (Prime Minister Narendra) Modi" remarks while criticising the BJP-led government on India-China border row.

Rahul has been consistent in his criticism of the government on the handling of both Covid-19 situation and India-China border row, which escalated into a "violent face-off" earlier this month in which 20 Indian soldiers were killed.

"Let there be a robust debate in Parliament. Let us have one. Let us discuss from 1962. Nobody is scared of debate. But one should not make a statement that makes Pakistan and China happy when the soldiers are fighting a spirited battle and the government is taking strong steps," he said.

Asked whether India can handle the anti-India propaganda unleashed by Rahul's 'Surrender Modi' hashtag, he said the government is capable of handling it but it is a matter of introspection for the former Congress president and his party that their remarks are being used against the country.

Modi's remarks at an all-party meeting that no one has intruded into Indian territory triggered a controversy with a section arguing that it went against the previous statement of External Affairs Minister S Jaishankar.

Claiming that he could not advise Rahul as it is Congress' job to do so, he said the government has fought Covid-19 well but some people have a twisted way of seeing things. He said India fought well against Covid-19 and the statistics will speak for itself as it is much better compared to the world.

Shah said under Modi's leadership, India is going to win both the battles -- Covid-19 and India-China border row.

The Home Minister also refused to be drawn into a question on whether Chinese soldiers are holding on to Indian territory on the border at present, saying the government is doing enough to address border row with China.

"I don't want to do anything that goes against my primary aim of this interview (to highlight the steps taken to fight Covid-19 pandemic in Delhi) and create headlines that keep citizens further in fear," Shah said.

When pointed out that people are also in panic due to the border situation, he said the government has taken steps to address the situation and at an appropriate time he would make comments, if needed.

Asked about his tweets on Emergency, which was targeted by Congress asking whether there is democracy in the BJP, he countered it saying that BJP has presidents L K Advani followed by Rajnath Singh, Nitin Gadkari, Rajnath again, himself and now J P Nadda.

"After Indira-ji, was there any Congress President from outside Gandhi family? What democracy do they talk about? I did not do any politics during Covid-19. You look at my tweets of the past 10 years. Every June 25, I give a statement," he said.

"Emergency should be remembered by people as it attacked the roots of our democracy. No one should ever forget it. There should be awareness about it. It is not about a party but about the attack on the country's democracy," he said.
