Godse remark: Congress leader Govardhan Dangi threatens to burn alive BJP's Pragya Thakur

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, Jun 24: With the highest single-day spike of 15,968 cases and 465 deaths in the last 24 hours, India's COVID-19 count reached 4,56,183 on Wednesday.

According to the latest update by the Union Ministry of Health and Family Welfare (MoHFW), 14,476 deaths have been recorded due to the infection so far in the country.

The count includes 1,83,022 active cases, and 2,58,685 cured/discharged/migrated patients.

Maharashtra with 1,39,010 confirmed cases remains the worst-affected by the infection so far in the country. The state's count includes 62,848 active, 69,631 cured, discharged patients while 6,531 deaths have been reported due to the infection so far.

Meanwhile, the national capital's confirmed coronavirus cases reached 66,602.

2,301 deaths have been reported in Delhi due to the infection so far.

Tamil Nadu has reported 64,603 cases so far with the death toll reaching 833.

Mumbai, Apr 22: Maharashtra Home Minister Anil Deshmukh on Wednesday said none of the 101 people arrested in connection with the Palghar lynching case is a Muslim, and accused the opposition of giving a communal colour to the incident.

Terming the incident as unfortunate and a blot on humanity, Deshmukh in a Facebook address said this is not the time to play politics, and urged all to engage in collective efforts to defeat the deadly coronavirus.

Without naming any leader or party, Deshmukh, who is an NCP leader, said some people were seeing Mungerilal ke haseen sapne (referring to a fictional character from a TV show who daydreams) of returning to power in the state.

He said in the run up to the incident, a rumour did rounds in Palghar that some people were lifting children during night.

The entire episode is being investigated by a special inspector general and the probe has been handed over to the Crime Investigation Department (CID), he said.

"The police arrested 101 people in connection with the incident within eight hours after it took place. They had run into neighbouring jungles, but were caught by police. There is no Muslim brother among these 101 people, Deshmukh said.

The minister said someone was heard as saying oye bas (please stop) in the video clip of the incident, but it was allegedly distorted as Shoaib.

An attempt was made to give a political colour to the incident. And this is very unfortunate...communal politics is being played, Deshmukh alleged.

He said such politics is being played at a time when the entire state is engaged in a battle against coronavirus.

"It is not the time to play politics, but to fight coronavirus collectively. It is unfortunate some people are seeing 'Mungerilal ke haseen sapne' at this juncture, the minister said.

The incident took place on the night of April 16 when three men - two seers and their driver - were going from Mumbai in a car towards Surat in Gujarat to attend a funeral.

Their vehicle was stopped near a village in Palghar district where the three were dragged out of the car and beaten to death with sticks by a mob on suspicion that they were child-lifters.

The deceased were identified as Chikne Maharaj Kalpavrukshagiri (70), Sushilgiri Maharaj (35), and driver Nilesh Telgade (30).

The Maharashtra government earlier ordered a high- level probe into the incident, and two policemen from Palghar were suspended on Monday for alleged dereliction of duty.
