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.

Riyadh, May 13: Saudi Arabia’s cabinet on Tuesday urged oil-producing nations not only to adhere to agreed cuts to production, but further reduce output to help restore balance in global oil markets, state news agency SPA reported.

In issuing the call to OPEC+, which includes members of the Organization of the Petroleum Exporting Countries plus Russia and other nations, ministers said the Kingdom is committed to supporting the stability of global oil markets.

After the meeting, acting Minister of Media Majed Al-Qasabi said that in addition to its commitment to the OPEC+ agreement, the Kingdom will voluntarily reduce output by an additional 1 million barrels a day in June. It will also try to implement additional cuts this month, with the consent of its customers, he added.

The cabinet said the Saudi initiatives aim to encourage other countries, whether they have signed up to the OPEC+ agreement or not, to adhere to its reduced rates and to cut output even further to help stabilize global oil markets.

During the cabinet meeting, which was conducted using video conferencing, King Salman also briefed ministers on his recent telephone conversation with US President Donald Trump. He said they affirmed the historical and strategic relationship between the two countries and their commitment to the continuation of joint efforts to enhance security and stability in the region.

Ministers were then updated on the latest developments in the corona virus crisis, including the steps being taken locally and internationally to control it and safeguard public health, the number of cases in the Kingdom and the care being provided to those who are infected. They also reviewed details of the active screening and testing programs in all parts of the country, which have helped to keep the number of deaths relatively low compared to global rates.

The cabinet praised the efforts being made by government officials to combat the pandemic, and stressed that citizens and expatriates must abide by the precautionary and preventive measures introduced to prevent the spread of the virus.

Ministers described the decision by Saudi Arabia to host the Pledging Event for the Humanitarian Crisis in Yemen 2020 on June 2 as an extension of the Kingdom’s humanitarian and development contribution, which reflects its pioneering role in supporting its neighbor.

The cabinet also welcomed the formation of the new government in Iraq and reiterated Saudi Arabia’s support for the nation and its readiness to work with the new administration to strengthen relations and enhance security and stability in the region.

New Delhi, Jun 6: With 9,887 new positive cases reported in the last 24 hours, India's COVID-19 count touched 2,36,657 on Saturday surpassing Italy's latest tally of over 2.34 lakh, taking India to the sixth spot among countries with the highest caseloads of the virus.

The Union Ministry of Health and Family Welfare (MoHFW) said that India registered a spike of 9887 new cases and 294 deaths in the past 24 hours taking the tally to 1,15,942 active cases and 6642 deaths.

Today's count was the highest single-day spike in the country, which has now overtaken Italy, according to the tally posted by the Johns Hopkins University which posted that globally the coronavirus had infected over 66.64 lakh people and claimed over 3.91 lakh lives so far.

In india, the MoHFW informed that 1,14,073 persons have been cured/discharged/migrated so far.

Maharashtra remains the worst-hit State as the total number of COVID-19 positive cases reached 80,229. While the total number of active cases in the state stands at 42,224.

In Tamil Nadu, 28,694 cases have been detected so far while Delhi has reported 26,334 coronavirus cases.
