NO2 emission advancing in India, latest NASA air quality maps display

The emission of the nitrogen dioxide pollutant has gone up significantly in the South Asia region, including India, during the 2005-2014 period, severely affecting air quality in the process, NASA satellite maps show.
Nitrogen dioxide (NO2) is a yellow-brown gas that is a common emission from cars, power plants and industrial activity.

The US and Europe are among the largest emitters of nitrogen dioxide but both regions also showed the most dramatic reductions between 2005 and 2014, the maps showed.

“The main story in South Asia is increasing NO2 levels from 2005 to 2014 associated with booming economies and ambitious infrastructure development, such as new coal-burning power plants in the Chhattisgarh region of India,” NASA said in a statement.

“One of the largest increases occurred over Jamnagar (India), the site of the largest petrochemical complex in the world,” it added.

“Dhaka (Bangladesh) had the largest increase (79 percent) of any world city,” the statement noted.

Using new, high-resolution global satellite maps of air quality indicators, NASA scientists tracked air pollution trends over the last decade in various regions and 195 cities around the globe.

“These changes in air quality patterns are not random,” said lead researcher Bryan Duncan, atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“When governments step in and say we are going to build something here or we are going to regulate this pollutant, you see the impact in the data,” Duncan noted.

Duncan and his team examined observations made from 2005 to 2014 by the Dutch-Finnish ozone monitoring instrument aboard NASA’s Aura satellite.

One of the atmospheric gases the instrument detects is nitrogen dioxide.

Nitrogen dioxide can quickly transform into ground-level ozone, a major respiratory pollutant in urban smog. NO2 hotspots, used as an indicator of general air quality, occur over most major cities in developed and developing nations.

The science team analyzed year-to-year trends in nitrogen dioxide levels around the world.

They found that China, the world’s growing manufacturing hub, saw an increase of 20 to 50 percent in nitrogen dioxide, much of it occurring over the North China Plain.

Three major Chinese metropolitan areas — Beijing, Shanghai, and the Pearl River Delta — saw nitrogen dioxide reductions of as much as 40 percent.

The findings were presented on Monday at the American Geophysical Union meeting in San Francisco, US and published in the Journal of Geophysical Research.

Analysis

45% of Indians do not back up their data, files: Survey

The survey was conducted among 728 Avast and AVG users between February 20-March 25.

New Delhi, March 30 : Nearly half of Indians do not back up because they think their data or files are not important enough and most of those who back up their data, do it once a month, a survey said on Monday.

Other reasons cited by the respondents for not backing up their data included not knowing how to do it, not having time and forgetting about it, according to the survey by cybersecurity company Avast.

“It could be that many aren’t aware they are backing up, as it could be happening automatically, in the background, however, others really might not be backing up at all, thinking it is not worth it,” Luis Corrons, Security Evangelist at Avast, said in a statement.

“Losing personal documents, photos and videos can be a painful experience and it’s not until this happens that they realize how valuable it actually is,” Corrons added.

Of those who do back up their data, nearly 42 per cent Indians back up to a cloud storage, 36 42 per cent back up their data to an external hard drive, 23 42 per cent back up to a USB or flash disk, 18 42 per cent back up their phone to their PC, and 10 42 per cent back up to a network storage drive, the results showed.

Corrons recommended to back up data to two different locations, like the cloud, and a physical storage, like an external hard drive.

When it comes to iPhone and Android phone owners, the percentage that backs up is nearly the same, 69 per cent and 70 per cent respectively.

The percentage of smartphone owners that don’t know how to back up their data does not vary much between iPhone and Android owners, with 13 per cent and 17 per cent claiming not knowing how to, respectively, the study revealed.

Data loss can be caused by users accidentally deleting their data themselves, hardware damage and failure, as well as malware, causing valuable data such as photos, videos, documents, and messages to be lost forever.

Ransomware and other malware, such as wipers, can either encrypt or completely destroy files, and there is no guarantee that files can be decrypted if a ransom is paid.

The survey was conducted among 728 Avast and AVG users between February 20-March 25.

Global smartphone sales declines 14% in February: Report

New Delhi, March 30 : Amid the COVID-19 pandemic, market demand is fragile but global smartphone sales in February declined only 14 per cent compared to last year, thus showing some resilience, a new report has said.

From the supply-side, global smartphone shipments (sell-in) fell a slightly more, down 18 per cent compared to last year but again a lower than expected drop, according to Counterpoint Research.

As coronavirus spreads like wildfire around the globe, its impact on the technology industry is unprecedented.

The global smartphone market is largely a replacement market, meaning that smartphones are a discretionary purchase.

“While people may delay purchasing due to the coronavirus pandemic, especially in the early part of the crisis when the disruption and uncertainty are both high, they will still replace their smartphone at some point. This means that sales will not be entirely lost – just delayed,” Peter Richardson, VP and Research Director, Counterpoint Research, said in a statement.

Sell-in shipments, which represents the supply of smartphones, were relatively weaker, but February is a traditional low period for production, especially if it coincides with the Chinese New Year as was the case this year.

However China, the initial epicenter of the epidemic, did show a huge 38 per cent decline. But it is showing signs of a rebound already.

Overall, global smartphone sales in February showed weakness in many markets as consumers became cautious.

But with the growth of online channels, we saw sales shifting from offline to online. Offline sales in China fell more than 50 per cent during February.

But this fall was partially offset with stronger online sales, so the overall drop at 38 per cent, was not so severe.

“While China and South Korea are gradually recovering, the worst is far from over for many other parts of the world,” said Jene Park, Senior Analyst at Counterpoint.

In terms of the competitive landscape, the demand for Samsung smartphones remained stable due to the minimum exposure to the Chinese supply chain and China market demand, thus, capturing 22 per cent global smartphone market share in terms of sales volumes.

Apple felt some impact from the supply-side during the month both in China in early February and outside of China in the latter half of the month, which affected its sales performance.

However, Huawei which has maximum exposure to China from both supply and demand perspectives, actually performed well above expectations, selling more than 12 million smartphones during February, seeing just a 1 per cent drop in global market share.
