Over 250 terrorists killed in IAF air strikes, claims BJP chief Amit Shah

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, Jul 20: Alleging that 2,426 companies have "looted" people's savings to the tune of Rs 1.47 lakh crore from banks, Congress leader Rahul Gandhi has asked if the Prime Minister Narendra Modi led government will conduct a probe into it to punish those guilty.

"2,426 companies looted 1.47 lakh crore rupees of people's savings from banks. Will this government investigate this loot and punish the culprits?" Gandhi said on Twitter, without elaborating.

"Or will it allow them to flee like Nirav and Lalit Modi?" he asked.

Gandhi's attack came after media reports claimed that the All India Bank Employees Association (AIBEA) had released a list of 2,426 borrower accounts that have been categorised as “wilful defaulters” with dues amounting to Rs 1,47,350 crore to the banking system.

Singapore, Jun 2: Moody's Investors Service on Tuesday downgraded 11 Indian banks along with as many non-financial companies and infrastructure majors besides four government-related issuers following a downgrade of the Indian government's issuer rating to Baa3 from Baa2 with a negative outlook.

The rapid and widening spread of the coronavirus outbreak, deteriorating global economic outlook, volatile oil prices and asset price declines are creating a severe and extensive credit shock across many sectors, regions and markets, said Moody's.

The Indian banking sector has been affected given the disruptions to India's economic activity from the coronavirus outbreak, which is weakening borrowers' credit profiles, it added.

The 11 lenders include Bank of Baroda, Bank of India, Canara Bank, Central Bank of India, Export-Import Bank of India, HDFC Bank, Indian Overseas Bank, IndusInd Bank, Punjab National Bank, State Bank of India and Union Bank of India.

The 11 non-finance companies are Oil and Natural Gas Corporation, Hindustan Petroleum Corporation, Oil India, Indian Oil Corporation, Bharat Petroleum Corporation, Petronet LNG, Tata Consultancy Services, Infosys, Reliance Industries, UPL Corporation and Genpact.

The 11 infrastructure companies are NTPC, NHPC, National Highways Authority of India, Power Grid Corporation, Gail India, Adani Green Energy Restricted Group (RG-2), Adani Transmission Restricted Group, Adani Ports and Special Economic Zone, Adani Transmission, Adani Electricity Mumbai and Azure Power Solar Energy.

The four Indian government-related issuers are Indian Railway Finance Corporation, Housing and Urban Development Corporation, Power Finance Corporation and REC Ltd.

"Government-related issuers in India have been affected because of disruptions to India's economy which will weaken borrowers' credit profiles," said Moody's.
