New Delhi, Jul 16: With the highest single-day spike of 32,695 cases and 606 deaths reported in the last 24 hours, India's COVID-19 tally on Thursday reached 9,68,876, informed the Union Ministry of Health and Family Welfare on Thursday.

The total number of COVID-19 cases includes 3,31,146 active cases, 6,12,815 cured/discharged/migrated and 24,915 deaths.

As per the Ministry, Maharashtra -- the worst-affected state from the infection -- has a total of 2,75,640 COVID-19 cases and 10,928 fatalities. While Tamil Nadu has a tally of 1,51,820 cases and 2,167 deaths due to COVID-19.

Delhi has reported a total of 1,16,993 cases and 3,487 deaths due to COVID-19.

Meanwhile, as per the information provided by the Indian Council of Medical Research (ICMR), 1,27,39,490 samples have been tested for COVID-19 till 15th July, of these 3,26,826 samples were tested yesterday.

New Delhi, Mar 10: A military transport aircraft of the Indian Air Force (IAF) brought back 58 Indians from coronavirus-hit Iran on Tuesday, official said.

The aircraft, a C-17 Globemaster, was sent to Tehran on Monday evening.

About 2,000 Indians are living in Iran, a country that has witnessed increasing numbers of coronavirus cases in the last few days.

"The IAF aircraft has landed. Mission completed. On to the next," External Affairs Minister S Jaishankar tweeted.

In an earlier tweet, he said, "First batch of 58 Indian pilgrims being brought back from Iran. IAF C-17 taken off from Tehran and expected to land soon in Hindon."

"Thanks to the efforts of our Embassy @India_in_Iran and Indian medical team there, operating under challenging conditions. Thank you @IAF_MCC. Appreciate cooperation of Iranian authorities. We are working on the return of other Indians stranded there (sic)," Jaishankar added.

The aircraft landed at Hindon airbase in Ghaziabad, from where the passengers were take to a medical facility.

According to latest reports, 237 people have died of novel coronavirus in Iran while the number of positive cases stands at around 7,000.

It is the second such evacuation by the C-17 Globemaster in the last two weeks.

On February 27, 76 Indians and 36 foreign nationals were brought back from the Chinese city of Wuhan by the aircraft of the Indian Air Force.

The C-17 Globemaster is the largest military aircraft in the IAF's inventory. The plane can carry large combat equipment, troops and humanitarian aid across long distances in all weather conditions.

Four days ago, a Mahan airline plane brought swab samples of 300 Indians from Iran to India.

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.
