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.

Jan 27: The Andhra Pradesh Cabinet passed a resolution on Monday setting in motion the process for abolishing the state Legislative Council.

A similar resolution will now be adopted in the Legislative Assembly and sent to the Centre for necessary follow-up action.

With just nine members, the ruling YSR Congress is in minority in the 58-member Legislative Council. The opposition Telugu Desam Party (TDP) has an upper hand with 28 members and the ruling party could get a majority in the House only in 2021 when a number of opposition members will retire at the end of their six-year term.

The move by the Andhra Pradesh cabinet came after the Y S Jaganmohan Reddy government last week failed to pass in the Upper House of the state legislature two crucial Bills related to its plan of having three capitals for the state.

Andhra Pradesh Legislative Council Chairman M A Sharrif on January 22 referred to a select committee the two bills -- AP Decentralisation and Inclusive Development of All Regions Bill, 2020, and the AP Capital Region Development Authority (CRDA) Act (Repeal) Bill -- for deeper examination.

The chairman had said that he was using his discretionary powers under Rule 154 while referring the Bills to the select panel in line with the demand of the TDP.

Following this, the chief minister had told the Assembly, "We need to seriously think whether we need to have such a House which appears to be functioning with only political motives. It is not mandatory to have the Council, which is our own creation, and it is only for our convenience."

"So let us discuss the issue further on Monday and take a decision on whether or not to continue the Council," he had said.

In fact, the YSRC had on December 17 first threatened to abolish the Council when it became clear that the TDP was bent on blocking two Bills related to creation of a separate Commission for SCs and conversion of all government schools into English medium.

As the Legislature was adjourned sine dine on December 17, no further action was taken. But last week, the issue cropped up again as the TDP remained firm on its stand on opposing the three-capitals plan.

The YSRC managed to get two TDP members to its side, but the government failed to get the three capitals Bills passed in the Council.

"What will be the meaning of governance if the House of Elders does not allow good decisions to be taken in the interest of people and block enactment of laws? We need to seriously think about it… Whether we should have such a House or do away with it," the chief minister had said in the Assembly.

New Delhi, Feb 5: Kapil Baisala who opened fired at the Shaheen Bagh protest site last week is a member of the Aam Aadmi Party, police said on Tuesday, sparking a war of words between the BJP and the AAP.

While the BJP accused Chief Minister Arvind Kejriwal of "playing" with the security of the country, the AAP hit back, stating the saffron party was indulging "dirty politics".

Deputy Commissioner of Police (Crime Branch) Rajesh Deo said that Baisala and his father joined the AAP in early 2019.

Baisala's family, however, refuted the police's claim.

Kapil Baisala's uncle Fatesh Singh told PTI, "I have no idea where these photographs are circulating from. My nephew Kapil had no association with any political party nor does any other member from the family. My brother, Gaje Singh, (Baisala's father) fought assembly elections in 2008 on a Bahujan Samaj Party ticket and lost. After that no one from our family had any links with any political party."

Singh added that Baisala also doesn't have friends associated with the AAP or any other political party.

Gaje had also contested the 2012 civic body polls from the BSP, the police said.

The police officer said they seized Baisala's mobile phone and retrieved WhatsApp data.

On Saturday, Baisala fired two rounds in air at Shaheen Bagh. According to eyewitnesses, the man shouted "Hindu Rashtra Zindabad" and fired two rounds.

He was overpowered by the police and later arrested.

In the pictures, it was seen that he and his father joined the party in the presence of Atishi Marlena, Sanjay Singh and other leaders, sources said.

The police said on Thursday, Baisala, along with his friend Sarthak Larolla, went to Shaheen Bagh from his village on a bike.

Through CCTV footage, it was found they took the DND flyover, Maharani Bagh, Sarai Jullena and reached Holy Family hospital, a senior police officer said.

"Baisala was not comfortable on the bike as he had hidden the pistol near his waist. They entered the hospital's parking where he adjusted the pistol, used the washroom and headed towards Shaheen Bagh," the senior official added.

When they reached the protest site, Larolla left the spot with the motorcycle and Baisala's mobile phone. Later, Baisala fired two rounds in the air and was apprehended. The weapon was recovered from near the spot, the police said.

Larolla joined the investigation and the mobile phone was seized from his residence.

Baisala has been remanded to police remand for two days.

He had bought the pistol around seven years ago for his brother's marriage. The source of the weapon from where he procured it is yet to identified, police said.

The sources said Baisala was previously also involved in firing incident but was never caught nor was a case registered against him.

Hitting out at the AAP, BJP president J P Nadda accused Kejriwal of playing with the security of the country and said that the people will give the party a befitting reply.

"I want to make clear to Kejriwal that this country is bigger than any election, any government, and the country will not forgive those who play with its security. The people of Delhi will give a befitting reply," Nadda tweeted.

Senior AAP leader Sanjay Singh asked on whose directions was the Delhi Police accusing his party.

"Before the police revealed it (Baisala being an AAP member), how did BJP's Delhi president Manoj Tiwari come to know about it," Singh asked and accused the police of maligning the party.

Domestic flights resumed operations on a truncated schedule on Monday with the first aircraft departing from the Delhi Airport for Pune, more than two months after a nationwide lockdown was announced to combat COVID-19.

The first flight to take off was an IndiGo aircraft to Pune, flying passengers stranded in the national capital since the lockdown was announced on March 24.

Passengers were screened at the airport with electronic thermometers, and revised protocol for air travel that included santisation of luggage through ultra-violent scanners, and maintaining physical distancing.

Only asymptomatic passengers were allowed to enter the airport.

Passengers were also seen wearing face masks and face shields given to them at the embarkation point by the airline to minimise the chances of infection while onboard.

The first flight arrived at Delhi Airport from Ahmedabad – a SpiceJet aircraft – at around 8:00 am.

BJD Lok Sabha member Anubhav Mohanty was among those who took the Air Vistara flight to Bhubaneshwar that departed Delhi airport at 6:50 am.

The first flight to take off from Mumbai was an IndiGo aircraft that departed for Patna at 6:45 am, while passengers from Lucknow were the first to reach the financial capital on an IndiGo aircraft that touched down at 8:20 am.

The food & beverage and retail outlets, which were closed for the past 63 days, opened at Terminal 3 of Delhi’s Indira Gandhi International (IGI) Airport.

The flight services resumed after a day of long and hard negotiations between the Centre and the states on Sunday.

All states finally agreed to accept at least some flights but announced different quarantine and self-isolation rules for arriving passengers to address apprehension about infections being brought in from other cities.

The Centre had issued guidelines for all modes of domestic travel that advised all asymptomatic passengers to self-monitor their health parameters for 14 days on completion of the journey and report to health authorities if they displayed any symptoms for COVID-19.

However, the Centre had allowed state governments to prescribe their own health protocols for disembarking passengers which led to differential guidelines across the country.
