‘Modi govt will not tolerate this’: HRD minister to universities against CAA

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.

Thiruvananthapuram, May 12: Kerala Government on Tuesday issued modified guidelines for infrastructure arrangements and procedures to be followed to ensure smooth interstate movement of stranded persons during the lockdown.

"Necessary permission, if any, required from the State where you are presently located need to be taken for ensuring a smooth journey till Kerala border," read the order by the state government.

It has also made it clear that people will only be allowed to travel if they have the permit from the state government and local authorities.

"You are requested to start the journey only after receiving the travel permit from the Government of Kerala and the local authority of your present location to avoid any problem during travel. Those who reach at the check post without passes will not be allowed entry," it further read.

The orders by the government further read:

*To maintain social distancing norms, only 4 persons will be permitted to travel in a car, 5 in an SUV, 10 in a van and 25 in a bus. The maximum number of passengers in a van /bus will be half of the seating capacity).

*Keep sanitiser, use masks and maintain physical distancing throughout the journey.

*An exit and entry pass/passes shall be issued by the District Collectors to those persons who seek to go outside states to bring back their stranded child/ children, spouse and parent/s.

*Everybody including those coming from red zones shall remain under home quarantine for 14 days from the date of arrival.

*Only priority groups and persons will be allowed entry passes:

a) Those from neighbouring states seeking Medical aid in Kerala

b) Pregnant ladies with family

c) Family members including children separated due to lockdown

d) Students

e) Senior citizens with family members

f) Persons who had lost a job.

The guidelines further added that all luggage must be disinfected and temperature checks must be carried out with Infrared flash thermometer among other things.

Pune, Jan 21: The Pune session court on Tuesday rejected the bail application of accused Vikram Bhave in the Dabholkar murder case.
Last year, Pune Sessions Court had granted an extension of 90 days to the Central Bureau of Investigation (CBI) to file a charge-sheet against Bhave.

On August 17, 2019, the court had rejected Bhave's bail plea.

During the course of hearing, Special Public Prosecutor (SPP) Prakash Suryavanshi, appearing for the CBI, had in June last year contended that Bhave helped the assailants to escape.

The CBI had arrested Bhave and another accused Sanjeev Punalekar from Mumbai on May 25, 2019 in connection with the matter.

Founder of the Maharashtra Andhashraddha Nirmoolan Samiti (MANS), Dabholkar was shot dead by bike-borne assailants while returning home from a morning walk on August 20, 2013.
