This means that recent human output is only a tiny part of the total carbon dioxide that OCO-2 records as it looks down toward Earth's surface..No satellite before OCO-2 was capable of measuring carbon dioxide in fine enough detail to allow researchers to create maps of human emissions from the satellite data alone.Instead, earlier maps also incorporated estimates from economic data and 10mm hex nut modeling results.OCO-2 can even detect smaller, isolated emitting areas like individual cities," said research scientist Janne Hakkarainen, who led the study.Scientists have created the first global maps of human emissions of carbon dioxide ever, made solely from NASA satellite observations of the greenhouse gas.The team of scientists from the Finnish Meteorological Institute, produced three main maps from OCO-2 data, each centered on one of Earth's highest-emitting regions: the eastern United States, central Europe and East Asia."Currently, the background level of carbon dioxide in the atmosphere is about 400 parts per million, and human emissions within the past year may add only something like three parts per million to that total," said Hakkarainen.

The maps show widespread carbon dioxide across major urban areas and smaller pockets of high emissions. Human emissions of carbon dioxide have grown at a significant rate since the Industrial Revolution and the greenhouse gas lingers in the atmosphere for a century or more. Scientists have created the first global maps of human emissions of carbon dioxide ever, made solely from NASA satellite obser Scientists have created the first global maps of human emissions of carbon dioxide ever.The data-processing challenge was to isolate the signature of the recent emissions from the total amount, he said.Scientists have created the first global maps of human emissions of carbon dioxide ever.The team's new data-processing technique accounts for seasonal changes in carbon dioxide, the result of plant growth and dormancy, as well as the background carbon dioxide level.The maps, based on data from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite and generated with a new data-processing technique, agree well with inventories of known carbon dioxide emissions.The study was published in the journal Geophysical Research Letters."The research demonstrates the possibility of analysing joint satellite observations of carbon dioxide and other gases related to combustion processes to draw out information about the emissions sources," said Johanna Tamminen, head of the atmospheric remote sensing group at the Finnish Meteorological Institute

The country's steel output is at around 120 million tonnes and the government is aiming to achieve 300 million tonnes by 2030. It is likely to be completed by December," Singh said. Some plants functioning after modernisation are able to achieve 40 per cent of the capacity utlisation, while some up to 70 per cent.In the last six months, steel output has gone up by 15 lakh tonnes.1."There was recession in global steel sector and it had an impact on India as well. Our steel industry was in stress for more than three years. But the situation has changed in last six months," he said.. He said modernisation and expansion work of steel PSUs -- SAIL and RINL -- is expected to be completed by December this year and the renovated plants would heavy hex nutbe able to achieve 70 per cent capacity utilisation in the next six months.

It takes time to ramp up production be it in Bhilai, Rourkela or Bokaro. He also said that the country is not behind in producing high-end steel used in many sectors like defence.70 and private steel companies at 2. Stressing on improving plant efficiency, the minister said India lags behind when compared to the global standards. I am hopeful that in the next six months, we will be able to achieve 70 per cent capacity utlisation," he noted.The government has allowed import of technology and equipment freely with an aim of promoting transfer and adoption of latest technologies to facilitate production of value-added and high quality steel products at competitive costs, he added. On modernisation of steel PSUs, the minister said more than Rs 61,500 crore has been invested for expansion and modernisation of SAIL.While the global efficiency standard is 3 points, Indian PSUs stand at 1.Steel Minister Chaudhary Birender Singh said the country's steel output is at around 120 million tonnes and the government is aiming to achieve 300 million tonnes by 2030. New Delhi: India's steel industry has come out of the stress, with the exports going up by 57 per cent and imports declining by 34 per cent, the government told the Rajya Sabha today.
