Blending Synthetic Air To Measure Climate Change
2014-02-27 09:59:21

National Physical Laboratory Scientists at the National Physical Laboratory (NPL) have produced a synthetic air reference standard which can be used to accurately measure levels of carbon dioxide and methane in the atmosphere. This will greatly help scientists contribute to our understanding of climate change. A paper published in Analytical Chemistry describes how researchers at NPL have created a synthetic gas standard for the first time, which is comparable to the World...

2014-01-21 12:42:19

[ Watch The Video: Six Decades Of A Warming Earth ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Goddard Institute for Space Studies (GISS) in New York found that 2013 tied 2009 and 2006 for the seventh warmest year since 1880. GISS analyzes global surface temperatures and released an updated report on Tuesday on the 2013 temperatures from around the world. According to the report, the average temperature last year was 58.3 degree Fahrenheit, which is about 1.1 degrees...

NASA To Search For Climate Change Clues In The Tropopause

WASHINGTON, Jan. 17, 2014 /PRNewswire-USNewswire/ -- NASA's uncrewed Global Hawk research aircraft is in the western Pacific region on a mission to track changes in the upper atmosphere and help researchers understand how these changes affect Earth's climate. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Deployed from NASA's Dryden Flight Research Center in Edwards, Calif., the Global Hawk landed at Andersen Air Force Base in Guam Thursday at approximately 5 p.m....

Increased Mercury Levels In Arctic Ice Found Pushing Into Sea Water
2014-01-16 10:15:32

Gerard LeBlond for redorbit.com - Your Universe Online Researchers Dr. Chris Moore and Dr. Daniel Obrist, from Nevada's Desert Research Institute, have recently discovered an increased level of mercury in Arctic sea ice. The study, published in the journal Nature, also found that the element is contaminating sea water below. The researchers claim that the air above large cracks found in the ice of the Arctic is mixing vigorously pushing mercury down to the exposed seawater. This process...

NCAR scientists and partners next week will launch a field project in the tropical Pacific, a remote region that holds a key to understanding worldwide climate. The warm waters fuel huge clusters of thunderstorms that act as a global chimney, lofting gases and particles into the stratosphere and affecting the planet. Boulder, CO (PRWEB) January 07, 2014 Even though few people live in the western tropical Pacific Ocean, these remote waters affect billions of people by shaping climate and...

Noctilucent Clouds In Antarctica Being Studied Closely By NASA's AIM Mission
2013-12-24 11:17:05

[ Watch the Video: ScienceCasts: Electric-Blue Clouds Appear Over Antarctica ] Lee Rannals for redOrbit.com - Your Universe Online A group of electric-blue clouds are hovering over Antarctica right now, and NASA’s AIM spacecraft is helping scientists better understand them. Noctilucent clouds (NLCs) are the Earth’s highest clouds, forming at the edge of space, 51 miles above the Earth’s surface. From a plane, the clouds appear as slivers of light streaking across the sky,...

Pollen Has Considerable Influence On The Atmosphere And Air Quality
2013-12-19 05:37:05

redOrbit Staff & Wire Reports - Your Universe Online Pollen comprises one-third of the aerosol particles present in the Earth’s atmosphere, and the powdery substance reflects more sunlight than experts had previously believed, according to new research appearing in the journal Atmospheric Environment. The study, which was written by scientists at the Gwangju Institute of Science and Technology (GIST) in Korea and the Leibniz-Institute of Tropospheric Research (TROPOS), is...

Mystery Of Troposphere Warming Solved
2013-12-10 14:44:32

Lee Rannals for redOrbit.com - Your Universe Online A long-standing mystery surrounding unusual warming of planetary atmospheres is not just exclusive to our solar system, but is most likely universal, according to a paper published in the journal Nature Geoscience. In 1902 a scientist named Léon Teisserenc de Bort found a point in Earth’s atmosphere where the air stops cooling and begins growing warmer. This finding was surprising considering scientists knew that as you climb in...

NASA Developing Sodium Lidar To Help Examine Eartth’s Mesophere
2013-10-30 18:52:47

Peter Suciu for redOrbit.com – Your Universe Online Future trips to space will be looking closely at sodium. Not as in the salt that astronauts use to flavor their food and can be brought to space in small packets. NASA scientists are instead looking at the sodium – the sixth most abundant element in Earth’s crust – that exists in the mesosphere. While sodium is already used as a coolant in nuclear power plants and can be used as a desiccant to remove humidity, it is also found...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

Sky
2004-10-19 04:45:44

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...
