As People Stay Home, Air Pollution In North India At 20-Year Low: NASA

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.

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.

Kolkata, Jun 24: Trinamool Congress (TMC) MLA Tamonash Ghosh, who had tested positive for Covid-19 in May, died at a hospital here on Wednesday, party sources said.

He was 60.

The three-time MLA from the Falta assembly constituency in South 24 Parganas district was admitted to a hospital after he tested positive for the disease, they said.

He had several complications related to the heart and the kidney, the sources said.

"Very, very sad. Tamonash Ghosh, 3-time MLA from Falta & party treasurer since 1998 had to leave us today. Been with us for over 35 years, he was dedicated to the cause of the people & party. He contributed much through his social work," West Bengal Chief Minister and TMC supremo Mamata Banerjee tweeted.

"He has left a void that will be difficult to fill. On behalf of all of us, heartfelt condolences to his wife Jharna, his two daughters, friends and well-wishers," she added.

New Delhi, Jan 17: Airports in Srinagar and Jammu are to be “immediately” brought under the security cover of the CISF in view of the arrest of DSP Davinder Singh, a Jammu and Kashmir government order has said.

The two sensitive airports are to be “handed over” to the CISF by January 31, the order of the Jammu and Kashmir Home Department to the Director General of Police (DGP) said.

“This issue (CISF security at Srinagar and Jammu airports) has acquired immediacy in view of the recent developments relating to the arrest of Davinder Singh, DSP airport security, for trying to assist militants to travel to other parts of the country,” the order issued on Wednesday said.

Police had arrested Singh, a deputy superintendent of police, at Mir Bazar in Jammu and Kashmir’s Kulgam district on Saturday, along with Hizbul Mujahideen terrorists Naveed Baba and Altaf, besides a lawyer who was operating as an overground worker for terror outfits.

The two airports are guarded by the CRPF and the J-K Police at present.

The Union government had last year decided that the Central Industrial Security Force (CISF) will be handed over security of these two airports along with the one in Leh in view of their sensitive and strategic location and the threats it faced related to possible terrorist and hijack attempts.

CISF is the national civil aviation security force and at present it guards 61 airports including the ones at Delhi and Mumbai.

News agency had on January 13 reported that the Union home ministry sanctioned about 800 personnel to the CISF in order to take over security duties at the three airports of the newly created Union Territories of Jammu and Kashmir and Ladakh.

As per the original plan, the CISF was to take over Jammu airport by next month and the Srinagar and Leh airports after the spell of severe cold ends.

However, officials said, keeping in mind the arrest of the DSP and his alleged links, the latest order has been issued which also directs the J-K Police to make arrangements for accommodation, transport and other logistical requirements of the armed contingent of the CISF on a quick basis.

Once inducted at the most-sensitive Srinagar airport, the CISF will secure access control at both city and air side (tarmac area) while the CRPF will be responsible for securing the outer periphery. At the Jammu airport, the peripheral security duties will be rendered by the JK Police.

An assortment of surveillance and security gadgets like CCTVs, observation monitors, hand-held metal detectors, bullet-proof patrol vehicles and bomb detection and disposal equipment are also being provided by the airport operator, the Airports Authority of India (AAI), to the CISF.

The Union government sometime back made it clear that CISF will be the only civil airports guarding force and all such facilities in the country will be gradually brought under its command to bolster aviation security and tighten anti-terror and anti-hijack protocols.
