Los Alamos National Laboratory Scientists have uncovered key attributes of so-called “brown carbon” from wildfires. Scientists have uncovered key attributes of so-called “brown carbon” from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material’s warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the...

pollen in the atmosphere
2014-06-01 02:40:19

Marlene Cimons, National Science Foundation Researchers study water cycle and cloud formation and design computer algorithm models to understand impact In the past, many atmospheric scientists believed that pollen particles probably had a negligible effect on climate because they were so big. In recent years, however, as they began to realize that pollen particles were not as sturdy as they once thought, they have been rethinking their old assumptions. "Pollen can rupture and...

Unclouding Our View Of Future Climate

[ Watch The Video: Atmospheric General Circulation Changes Due To Increased Greenhouse Gases ] Carol Rasmussen, NASA's Jet Propulsion Laboratory If we had a second Earth, we could experiment with its atmosphere to see how increased levels of greenhouse gases would change it, without the risks that come with performing such an experiment. Since we don’t, scientists use global climate models. In the virtual Earths of the models, interlocking mathematical equations take the place...

Understanding How Sprites Form
2014-05-08 03:55:14

By A'ndrea Elyse Messer, Penn State Atmospheric sprites have been known for nearly a century, but their origins were a mystery. Now, a team of researchers has evidence that sprites form at plasma irregularities and may be useful in remote sensing of the lower ionosphere. "We are trying to understand the origins of this phenomenon," said Victor Pasko, professor of electrical engineering, Penn State. "We would like to know how sprites are initiated and how they develop." Sprites are...

NASA's AIM Mission Unlocks The Secrets Of Noctilucent Clouds
2014-04-17 08:10:25

[ Watch the Video: Unexpected Teleconnections in Noctilucent Clouds ] April Flowers for redOrbit.com - Your Universe Online When you think about the North and South poles, they seem to be worlds apart. They are separated by four oceans, six continents, and more than 12,000 nautical miles. New data from NASA's Aeronomy of Ice in the Mesophere (AIM) spacecraft suggests, however, that they aren't as far apart as you might think. AIM has revealed "teleconnections" in the planet's...

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...

2013 Seventh Warmest Year On Record
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

[ Watch the Video: Global Hawk Gets To Work In The Western Pacific ] redOrbit Staff & Wire Reports - Your Universe Online NASA has deployed their pilot-less Global Hawk research aircraft in the western Pacific in order to monitor changes to the upper atmosphere and discover how changes there are impacting the planet’s climate. The mission, announced by the US space agency on Friday, is part of their Airborne Tropical Tropopause Experiment (ATTREX) airborne science campaign....

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...

Earth's Atmosphere

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...
