Nirav Modi tracked down to swanky London apartment: report

Thiruvananthapuram, Mar 29: Kerala Chief Minister Pinarayi Vijayan on Saturday expressed his concern over the ''non-cooperation from the Karnataka Government in removing the roadblocks erected by them in the roads bordering Malapuram district''.

Addressing a press conference at the Government Secretariat, the Chief Minister said, "Karnataka has not heeded to our request to remove the roadblocks. I have been trying to contact their Chief Minister B S Yeddyurappa but not able to reach him."

"We have briefed the Union Minister D V Sadananda Gowda and he has offered to resolve the issue. Our Chief Secretary has also briefed the Central Cabinet Secretary and we expect a resolution soon," he added.

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.

Panaji, Mar 26: Three persons, all with travel history abroad, tested positive for coronavirus in Goa on Wednesday, health department officials said, as the tourist haven joined the states which have reported COVID-19 cases.

This is the first time the tourist state has reported coronavirus positive cases.

The Directorate of Health Services, in a late night press statement here, said three suspected cases of COVID-19 from Goa, whose test results were awaited, have turned out positive.

All three are male patients of ages 25, 29 and 55 years. They have travel history of returning to Goa from Spain, Australia and the USA, respectively, the officials said.

The condition of the trio, admitted in Goa Medical College and Hospital near here, is stable, the officials added.

Chief Minister Pramod Sawant said the state is providing the best healthcare facility to the diagnosed patients.

I have been informed by the state Directorate of Health services that three individuals have been tested positive for #COVID19 in Goa.

"We are providing the best healthcare facility to the diagnosed patients, he said.

Their condition is stable at present. e have also traced their contacts and are quarantining them, Sawant added.

Health Minister Vishwajit Rane said the government is taking all precautions and following guidelines related to the viral infection.

In view of the three positive coronavirus cases in Goa, we are following all guidelines laid down by the central government and taking all precautions with the support of chief minister Pramod Sawant, he said.

Our testing facility will be up and running in the next two days. Our team of doctors is doing its est to make sure we contain the spread of virus in the state, Rane added.
