Ramzan prayers: Now Muslims protest in Jalandhar

Thiruvananthapuram, Apr 27: Over 1.5 lakh Non-Resident Keralites (NRK)s, stranded in various countries, have registered online for returningto the state, once the Centre gives the nod and air services resume

The Norka (Non Resident Keralites Affairs) department had commenced the registration process at around 6pm on Sunday and within an hour 25,000 had registered, government sources said.

Till Monday morning, over 1.5 lakh NRKs have registered, the maximum is from UAE-- over 60,000.

The aged, pregnant women, children, critically ill patients, those with expired visas and those who had gone abroad on visiting visa are among thelarge numbers of people who are waiting to return.

Those wanting to return, have to get themselves tested for COVID-19 in the respective countries, where they are and register after getting a negative certificate for the infection.

Theregistration is for arranging quarantine facilitiesin the state, if necessary, and not for getting any priority on flight bookings,the sources said.

After the NRKs register themselves, the government would draw up a list on how to bring them back as per priority.

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, May 3: Union Health and Family Welfare Minister Dr Harsh Vardhan on Sunday said that India's COVID-19 mortality rate of 3.2 per cent is the lowest in the world and over 10,000 coronavirus patients have been discharged from hospitals after recovering from the disease so far.

"Today more than 10,000 COVID-19 patients have been discharged. Those still admitted at hospitals are on the road to recovery. If in last 14 days doubling rate was 10.5 days, then today it is around 12 days," the Minister told ANI after visiting Lady Hardinge Hospital.

"Our mortality rate of 3.2 per cent is the lowest in the world," he said.

With 2,644 more COVID-19 cases and 83 deaths in the last 24 hours, the number of people infected from coronavirus in the country has reached 39,980 including 1,301 deaths, said the Union Ministry of Health and Family Welfare on Sunday.

Currently, there are 28,046 active cases while 10,633 COVID-19 positive patients have been cured/discharged.
