14 killed, 7 injured in GAIL pipeline fire

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.

Apr 23: Mukesh Ambani is again Asia's richest person after a deal with Mark Zuckerberg's Facebook Inc. sent his conglomerate's stock surging.

Ambani's fortune rose about $4.7 billion to $49.2 billion on Wednesday, after Reliance Industries Ltd. gained 10%. The jump put Ambani about $3.2 billion ahead of China's Jack Ma, according to the Bloomberg Billionaires Index. The ranking updates after the close of each trading day in the U.S.

Facebook Inc. will invest $5.7 billion in the U.S. social-networking giant's biggest deal since the 2014 purchase of WhatsApp as it seeks a broader foothold in its biggest global market. The U.S. company will buy about 10% of Jio Platforms, which brings together digital apps and a wireless platform under one umbrella, the Mumbai-based company said in a statement Wednesday.

Before Wednesday, Ambani -- who owns the world's largest oil refinery -- had declined by $14 billion on the index in 2020, the biggest dollar fall of anyone in Asia. Alibaba Group Holding Ltd.'s Ma, whose foundation this week donated 100 million masks to the World Health Organization to fight the Covid-19 pandemic, had lost almost $1 billion through Tuesday.

"At the core of our partnership is the commitment that Mark Zuckerberg, founder of Facebook, and I share for the all-around digital transformation of India," Ambani said in a web video posted on Jio's Facebook page, adding that Facebook's brands have become household names in India. "WhatsApp in particular, has entered our people's daily vocabulary in all the 23 official languages of India."

The partnership with Jio would allow Zuckerberg to step up his expansion in a country that is rapidly embracing online payment and e-commerce as more people get smartphones. Jio Infocomm quickly moved into a position of dominance by offering free plans and undercutting wireless market rivals.

With its half-billion internet users, the South Asian country is a key market for the world's largest technology companies, including Amazon.com Inc., Apple Inc., Microsoft Corp. and Alphabet Inc.'s Google. In India, Facebook has about 250 million users, while WhatsApp has more than 400 million.

That should help Jio bolster its reach, according to James Crabtree, author of 'The Billionaire Raj,' a book on the country's wealthiest people. But the transaction also shows the extent of Ambani's own influence, he said.

"This deal clearly shows that if you want to play big in Indian tech, you need to play nice with Mukesh Ambani."

Daman, Mar 3: A BJP councillor was shot dead on Monday in the Union Territory of Daman, police said.

Salim Memon was sitting in his motorcycle showroom when three to four unidentified persons shot four to five bullets after asking a visitor there to move out, an official said quoting eye-witnesses.

While fleeing, they also shot two rounds close to this visitor who was standing outside, he said.

"Memon was rushed to a hospital in Marwad area but was declared dead on arrival. CCTV footage is being scanned to nab the culprits," said Daman Superintendent of Police Vikramjit Singh.

Memon was elected to Daman municipality as a Congress candidate but then switched over to the BJP.

Sources said Memon, who also has a land brokerage business, had come out of jail a few months back in connection with a case of rivalry.
