Nawaz Sharif greets PM Modi on I-Day,hopes to settle issues through talks

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.

Jaipur, Jul 18: BJP leader Laxmikant Bhardwaj filed a complaint against Congress leaders including Randeep Surjewala and Govind Singh Dotasra for associating Union Minister Gajendra Singh Shekhawat's name with an alleged audio clip related to "conspiring to topple" the elected government led by Chief Minister Ashok Gehlot in Rajasthan.

"Mahesh Joshi, Randeep Surjewala, and other accused have regularly been giving false and inflammatory statements against the BJP to criminally damage its reputation so that the blame for the current sorry state of affairs of the Congress can be pinned on the BJP. With the ill-intention of damaging the BJP''s reputation, a conspiracy was formed at the Chief Minister''s residence situated at 8 Civil lines," read the letter written by BJP Rajasthan spokesperson Bhardwaj to the Station Officer of Ashok Nagar police station read.

"From there (CM's residence) imitation of (voices) of people were falsely told to be of that of reputed leaders from the BJP and a fake phone conversation was created through which the false narrative of crores of rupees being offered to buy off Congress MLAs was created. The accused involved in this conspiracy have severely misused their position and power and the whole crime has been conducted by one named Lokesh Sharma, who calls himself an OSD of the Chief Minister," the letter further stated.

The complaint letter also said that Lokesh Sharma had "released three audio tapes to media workers on July 16, 2020, somewhere around 8:25 pm through WhatsApp so that the defamatory material can be circulated on a large scale to fulfill the criminal intent."

Mr Bhardwaj said that a news report in the Jaipur edition of a Hindi newspaper, published on July 17, 2020, had conveyed that the audiotape was released by Mr Sharma.

He further said that Congress leaders Randeep Surjewala, Govind Singh Dotasra, in a press conference held on Friday read out the conversation in the audio tapes publically and "using them as a basis accused the BJP of throttling democracy, sabotaging the mandate, and toppling the government."

Through this conspiracy, Mr Bhardwaj said that hateful and insulting comments are being made on the BJP and its supporters, and "on the basis of this the Special Operation Group (SOG) has filed fake lawsuits under Section 124A of the Indian Penal Code and is also threatening BJP leaders of arrest."

The BJP leader has urged the police officer to file a complaint against Mr Sharma, Mr Surjewala, Mr Dotasra, and others involved in the alleged conspiracy and take necessary action and recover the equipment used by them.

On June 17, Congress spokesperson Randeep Surjewala had accused Union Cabinet Minister Gajendra Singh Shekhawat and Congress legislator Bhanwarlal Sharma of conspiring to topple the elected government led by Chief Minister Ashok Gehlot in Rajasthan and subvert the voters' mandate.

"Yesterday, shocking tapes were aired by the media in which Union Minister Gajendra Singh Shekhawat, BJP leader Sanjay Jain and Congress MLA Bhanwar Lal Sharma spoke about bribing MLAs and bringing down Rajasthan government. Congress has suspended MLAs Bhanwar Lal Sharma and Vishvendra Singh from the primary membership of the party. The party has also issued show-cause notices to them," Mr Surjewala had said.

"We demand Rajasthan government and Special Operations Group (SOG) to register FIR and arrest the culprits as plenty of evidence has surfaced now," he had further stated.

Mr Surjewala had read out a transcript of an audio of alleged horse-trading between rebel MLAs and BJP, stating, "BJP has breached the trust of people. The audio clip reveals a horse-trading deal. This is a dark chapter in the history of democracy."

"This time the Narendra Modi government has challenged the wrong state," the Congress leader had said. He had alleged that the BJP has been "conspiring to topple Rajasthan government and buy legislators' allegiance."
