Somnath Bharti denies 'tampering with evidence', CM Kejriwal defends him

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.

Ahmedabad, June 6: Rattled by resignations of three MLAs ahead of the June 19 Rajya Sabha polls, the Congress in Gujarat on Saturday shifted several of its legislators to resorts and bungalows near their constituencies to thwart any "poaching" bid, a party leader said.

With the resignations of Akshay Patel and Jitu Chaudhary on June 3 and that of Brijesh Merja on June 5, the Congress' strength in the 182-member House has been reduced to 65.

The effective strength of the House, however, stands at 172 as of now as ten seats are currently vacant - two due to court cases and the rest because of resignations.

While several MLAs from north Gujarat were shifted to a resort near Ambaji in Banaskantha district, those from south and Central Gujarat were moved to private bungalows in Anand, Congress spokesperson Manish Doshi said, adding that legislators from Saurashtra region were shifted to a resort in Rajkot.
 

New Delhi, Feb 9: Calling India a "long-standing friend", Sri Lankan Prime Minister Mahinda Rajapaksa on Saturday thanked Prime Minister Narendra Modi for visiting his country in the aftermath of last year's Easter Sunday terror attacks and outlined that New Delhi has always helped Colombo in its fight against terrorism.

In a joint press briefing with PM Modi, Mahinda Rajapaksa said he hopes that India will continue to help Sri Lanka fight terrorism.

Mahinda Rajapaksa expressed his gratitude to PM Modi for the neighbourhood first policy and the priority India gives to Sri Lanka.

"We had agreed that our cooperation is multifaceted and priority is given to a number of areas including security, economy, culture and social sectors. Part of our discussions centered on cooperation with regard to the security of the two countries. India has always assisted Sri Lanka to enhance our capacity, capabilities in intelligence and counter-terrorism. We look forward to getting continued support in this regard," he said.

"I thank the Prime Minister for visiting Sri Lanka in the aftermath of the Easter Sunday terror attacks that provided us with immense strength to come to terms with the tragedy. We also appreciate Prime Minister Modi's $400 million line of credit to enhance the economy of Sri Lanka and another $50 million line of credit for fighting terrorism," he added.

The Sri Lankan president urged PM Modi to consider further assistance to expand housing projectS all over Sri Lanka to benefit people from rural areas.

"The Prime Minister and I discussed how Sri Lanka and India can work together in the field of economy. India is among the world's fastest growing economies. I discussed with PM Modi how Sri Lanka could benefit from certain economic sectors where India is in a strong position," he said.

Concluding his statement, Mahinda Rajapaksa said, "India is our closest neighbour and a long-standing friend. The close historical links...provided a solid foundation to our ties."
