Modi terms Rahul Gandhi's elevation as 'Aurangzebi raj'

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.

Pulwama, May 28: A major incident of a vehicle-borne IED blast was averted by the timely input and action by Pulwama Police, Central Reserve Police Force (CRPF) and Army, the Jammu and Kashmir Police said.

According to sources, Pulwama Police got credible information last night about a terrorist moving with an explosive-laden car ready to blast at some location. They took out various parties of police and security forces and covered all possible routes keeping themselves and the police and security forces away from the road at safer locations.

The suspected vehicle came and a few rounds were fired towards it. A little ahead this vehicle was abandoned and the driver escaped in the darkness. On close look, the vehicle was seen to be carrying heavy explosives in a drum on the rear seat. Possibly more explosive would be fitted elsewhere in the vehicle, sources added.

The vehicle was kept under watch for the night. People in nearby houses were evacuated and the vehicle exploded in situ by the Bomb Disposal Squad as moving the vehicle would have involved serious threat, sources said.

The vehicle reportedly sports a number plate of a scooter registered somewhere in Kathua district of Jammu zone, sources added.

Kanpur,  Jul 3: A total of eight police personnel including Deputy Superintendent of Police Devendra Mishra have lost their lives after they were fired upon by criminals in the early hours of Friday.

The incident took place when a police team had gone to raid history-sheeter Vikas Dubey's house.

Senior Superintendent of Police and Inspector General of Police have reached the spot and forensics team is examining the area.

State Chief Minister Yogi Adityanath has expressed his condolence to the families of the eight Police personnel who lost their lives after being fired upon by criminals in Kanpur. He has directed Director General of Police HC Awasthi to take strict action against criminals. He also sought a report of the incident.
