‘Army killed this 12-year-old girl when she was giving water to an injured relative’

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.

Kollam, Feb 29: Seven-year-old Devananda, whose body was found in a lake, was laid to rest at Kudavattoor in the Kollam district of Kerala on Friday evening.

She was laid to rest near her father Pradeep Kumar's house in Kudavattoor. Earlier, the body was kept at her mother Dhanya's house in Ilavoor and Vakkanadu school, where she studied in Class 1, for the public to pay respect.

Hundreds of people visited to pay their last respects to the child.

An intense social media campaign was launched to trace the child after she was reported missing on Thursday morning.

According to police, an autopsy conducted in Thiruvananthapuram Medical College led to a preliminary conclusion that the cause of death was drowning. Residues of mud and silt have been found in her respiratory tract.

Signs of any kind of violence inflicted on the child have been ruled out. The body was released to the family after the autopsy.

Chief Minister of Kerala Pinarayi Vijayan and Opposition leader Ramesh Chennithala, BJP state president K Surendran were among many politicians who offered the condolences.

Many celebrities including Mammootty, Dulqar Salman, Kunchako Boban took to Facebook to pay their tribute to Devananda.

New Delhi, Jun 13: Petrol price on Saturday was hiked by 59 paise per litre and diesel by 58 paise as oil companies for the seventh day in a row adjusted retail rates in line with costs since ending an 82-day hiatus in rate revision.

Petrol price in Delhi was hiked to Rs 75.16 per litre from Rs 74.57, while diesel rates were increased to Rs 73.39 a litre from Rs 72.81, according to a price notification of state oil marketing companies.

Rates have been increased across the country and vary from state to state depending on the incidence of local sales tax or VAT.

This is the seventh daily increase in rates in a row since oil companies on Sunday restarted revising prices in line with costs, after ending an 82-day hiatus.

In seven hikes, petrol price has gone up by Rs 3.9 per litre and diesel by Rs 4.

The freeze in rates was imposed in mid-March soon after the government hiked excise duty on petrol and diesel to shore up additional finances.

Oil PSUs Indian Oil Corp (IOC), Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corp Ltd (HPCL), instead of passing on the excise duty hikes to customers, adjusted them against the fall in the retail rates that was warranted because of a decline in international oil prices.
