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.

New Delhi, Jun 26: With the highest single-day spike of 17,296 COVID-19 cases reported in the last 24 hours, India's COVID-19 count reached 4,90,401 on Friday, said the Union Ministry of Health and Family Welfare (MoHFW).

The country also saw 407 deaths in the last 24 hours, which pushed the death toll to 15,301.

The total number of cases includes 1,89,463 active cases, 2,85,637cured/discharged/migrated cases, as per the MoHFW.

According to the Indian Council of Medical Research (ICMR), the total number of samples tested up to June 25 is 77,76,228; the number of samples tested on 25 June is 2,15,446.

Maharashtra remains the worst-affected state in the country with 1,47,741 cases. The active cases in the state are 63,357. The number of people cured or discharged stands at 77,453 while the death toll is at 6,931.

Delhi has so far reported 73,780 cases. The active cases in the national capital stood at 26,586. While the cured and discharged numbers stood at 44,765. The death toll in the city is 2,429.

Tamil Nadu has so far reported 70,977. With active cases at 30,067 and the number of cured or discharged at 39,999, while the death toll stood at 911.

Bhopal, Jun 20: A senior BJP MLA in Madhya Pradesh tested COVID-19 positive hours after he cast his vote for the Rajya Sabha polls in the state and attended party meetings, an official said on Saturday. The legislator's wife has also tested positive for the infection, he said.

Voting for three Rajya Sabha seats in the state took place on Friday.

The couple's test reports came on Friday night and the news of the MLA's infection triggered panic among other MLAs with some of them reaching hospitals to get themselves tested.

"The MLA and his wife were found infected with COVID- 19 in the tests conducted by a private laboratory. We are examining their condition and making a decision whether they need to be hospitalised or home quarantined," a health department official told.

He said that the MLA's contact tracing has been initiated.

"Further tests are also being conducted," he said.

He is the second legislator in Madhya Pradesh, who was tested coronavirus positive.

Earlier, a Congress MLA was found infected. He had voted for the Rajya Sabha polls on Friday after reaching the state assembly complex wearing a PPE suit.

Talking to , a member of the BJP MLA's family said that the medical team was called on Friday afternoon for the COVID-19 test after the legislator's wife complained of uneasiness.

"The MLA and his wife gave the samples to the medical team for the COVID-19 tests on Friday afternoon and they were told at night that both of them have tested positive for the infection," he said.

After the news of BJP MLA testing positive spread, a senior BJP MLA from Mandsaur, Yashpal Singh Sisodiya, reached government-run J P Hospital here along with two other party MLAs.

Talking to reporters, Sisodiya said, "I came here along with two other MLAs from our division- Dilip Makwana (Ratlam Rural) and Devilal Dhakad (Garoth)- after we came to know through media and social media that one of the MLAs from our division has tested positive for COVID-19."

"We don't have any symptoms, but came to test for COVID-19 as a precautionary measure," he said.

Dhakad said that he came for testing as he had dined with the MLA two days back.

Talking to , Madhya Pradesh State Assembly's Principal Secretary A P Singh said that all the precautionary measures were taken during the Rajya Sabha polling.

"All employees were in safety gears during the Rajya Sabha election process. The assembly campus was being sanitised every 15-20 minutes during the polling process...We are now going through the CCTV footage to trace those who had come in his contact," he said.

Congress MLA and former minister P C Sharma said that those who came in contact with the BJP legislator should be traced and quarantined.

"The employees and MLAs who came in contact with him during the voting process should be tested," Sharma said.
