Modi govt slammed for misleading families of missing Indians

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 1: 18,653 COVID-19 cases have been reported in India in the last 24 hours, taking the country's tally of coronavirus cases to 5,85,493, informed the Union Health and Family Welfare Ministry on Wednesday.

As per the Ministry, there are presently 2,20,114 active cases in the country. The number of patients cured/discharged and migrated stands at 3,47,979.

507 deaths due to COVID-19 were reported in the last 24 hours taking the total deaths due to the virus to 17,400.

According to the ministry, Maharashtra is the worst-affected state by the virus with 1,74,761 cases including 7,855 fatalities.

Tamil Nadu is the second worst-hit state with 90,167 cases including 1,201 deaths. Meanwhile, Delhi has a total of 87,360 cases.

The Indian Council of Medical Research said that a total number of 86,26,585 tested up to June 30 of which 2,17,931 samples were tested on Tuesday.

Mumbai, Jan 30: The Uttar Pradesh Special Task Force (STF) has arrested Dr Kafeel Khan from Mumbai airport for allegedly making inflammatory statements at AMU during protests against the Citizenship Amendments Act (CAA) last month, officials said.

Khan was arrested on Wednesday night with assistance from Mumbai Police at the airport when he arrived in the city to attend anti-CAA protests, an official said.

"Officials of the UP STF arrested Dr Kafeel Khan in a case which was registered at Civil Lines Police Station under section 153 A (promoting enmity between different groups) of IPC. Our police team helped our UP counterparts on their request," said an official from Mumbai Police.

He claimed that Khan had made inflammatory statements on December 12 last year during the protest near Bab e Syed Gate outside the Aligarh Muslim University in front of more than 600 students.

The official also alleged that the Gorakhpur doctor had made objectionable comments against Union Home Minister Amit Shah.

The FIR against Khan mentions that Swaraj India's president Yogendra Yadav was also present during the speech at AMU.

Following the arrest in the case, Khan was taken to the Sahar Police Station and after completing formalities he will be taken to UP on transit remand, the official said.

Khan, a paediatrician, had come to the limelight in 2017 when a controversy broke out after the death of over 60 children in less than a week at the BRD Medical College in Gorakhpur, UP.
