Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship …
This factsheet provides the information on the Atmospheric Infrared Sounder(AIRS), which advances climate research and weather prediction into the 21st century. AIRS is one of six instruments onboard Aqua, a satellite that is part of NASA
How does a spaceborne instrument like AIRS extract carbon dioxide from Earth's atmosphere, and what is its data revealing? The level of carbon dioxide in the Earth's atmosphere has been on the rise since the late 19th century. Charles David Keeling first proved this by careful measurements of samples collected …
A NASA/university team has published the first global satellite maps of the key greenhouse gas carbon dioxide in Earth's mid-troposphere, an area about 8 kilometers, or 5 miles, above Earth. The team's study reveals new information on how carbon dioxide, which directly contributes to climate change, is distributed in Earth's …
Carbon dioxide (CO2) is the principal man-made greenhouse gas and the primary atmospheric component of the global carbon cycle. Precise ground-based measurements of CO2 made since the late 1950s indicate that the atmospheric CO2 concentration has increased from ~310 to over 380 parts per million (ppm) over this period [1]. …
A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region
Scientists studying variations in tropical heat and rainfall since the mid-1980s have found a strong link between warm periods and a rise in the frequency of the most extreme downpours. The observed rise in the heaviest tropical rains is about twice that produced by computer simulations used to assess how …
Ranchi, Aug. 3: For 16 students of city-based Sapphire International School, flying a space craft at Nasa's space research centre at Albama in the US will become a reality this October. This is the first time that state students are going to Nasa. The school management is currently preparing the …
Alleging that the Red Indian Horned Owl, locally known as hoodoo, is being sold to NASA for facilitating research works, People for Animals, a non-government organisation working against cruelty against animals, has decided to move Chief Minister Tarun Gogoi urging the latter to initiate measures for protection of the endangered …
Cape Canaveral (Florida): With astronauts hustling inside and out, the international space station got its biggest live-in addition yet, a Japanese lab stretching 37 feet that opens for business on Wednesday. Japanese astronaut Akihiko Hoshide had the honor of installing the billion-dollar lab, named Kibo, which means "hope', just as …
"Political appointees" in NASA's press office "marginalized, or mischaracterized" studies on global warming between 2004 and 2006, the space agency's inspector general said in a report released today. The IG called the deliberate distortions "inappropriate political interference," and "found no credible evidence suggesting that senior NASA or Administration officials directed …
infoholic Yup, I can dig into frozen ground as hard as concrete. The scoop has special blades and a powered "rasp' to scrape ice. Cool! Whoever thought a Nasa spacecraft could be so adept at social networking and internet? For users of Twitter, a web microblogging service, the Phoenix Mars …
As the long quest for alien life goes on and with the discovery of earth-like planets outside the solar system in distant galaxies, here is a surprising find in our own neighbourhood. NASA's Cassini spacecraft has discovered evidence that points to the existence of an underground ocean of water and …
Until the second week of September, when both the ruling Congress and the Opposition Bharatiya Janata Party (BJP) suddenly discovered that the affidavit filed by the Archaeological Survey of India (ASI) in the Supreme Court on the Sethusamudram Ship Channel Project was controversial and hurt religious sentiments, the biggest political …
