Meteor Smoke Helps Form Noctilucent Clouds
2012-08-08 13:33:19

Watch the Video : [ Meteor Smoke Makes Strange Clouds ] Lee Rannals for redOrbit.com - Your Universe Online Bits of "meteor smoke" have been detected in a noctilucent cloud (NLC), supporting an already existing theory. Noctilucent clouds were first noticed in 1885 about two years after the eruption of Krakatoa. Ash from the volcano caused great sunsets, making it a global past time for people to sit and look up at the sky at dust. A German named T.W. Backhouse, who is credited...

Foreign Airborne Aerosols Invade North America

[ Watch the Video: Imported Dust in American Skies ] April Flowers for redOrbit.com - Your Universe Online In a joint study between NASA and University of Maryland, College Park, scientists have made the first measurement-based estimate of the amount and composition of tiny airborne particles that arrive over North America each year. With a 3D view of the atmosphere now possible from satellites, the team calculated that dust, not pollution, is the main ingredient. According to the...

WASHINGTON, Aug. 2, 2012 /PRNewswire-USNewswire/ -- NASA and university scientists have made the first measurement-based estimate of the amount and composition of tiny airborne particles that arrive in the air over North America each year. With a 3-D view of the atmosphere now possible from satellites, the scientists calculated that dust, not pollution, is the main ingredient of these imports.

Summer Storms Cause Ozone Depletion In United States
2012-07-27 09:49:29

Lawrence LeBlond for redOrbit.com - Your Universe Online It was in the 1970s that the British Antarctic Survey discovered a hole in the ozone layer above the Antarctic Circle, and in 1985, when the first measurements were taken, researchers were dumbfounded by the dramatic drop in ozone levels. The concern was so great that it eventually led to the ban of all products containing chlorofluorocarbons (CFCs), which were confirmed to be the root cause of the ozone depletion. Fast forward...

Art And Science Collide in New Solar Imaging Technique
2012-07-22 07:05:56

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online In what can be described as a melding of astronomy and post-Impressionist art, one NASA solar scientist has developed a new technique that uses bright, bold colors to share information about the heating and cooling of various parts of the sun. Nicholeen Viall of the NASA Goddard Space Flight Center in Greenbelt, Maryland innovated this new method, which uses various hues splashed across a yellow background...

Gravity Satellite Will Benefit Future Missions
2012-07-20 15:21:31

ESA´s GOCE satellite is not only mapping Earth´s gravity with unrivalled precision, but is also revealing new insight into air density and wind in space. This additional information is expected to improve the design and operation of future Earth observation missions. Most satellites orbit Earth higher than 400 km. Lower than that and atmospheric drag causes them to slow down quickly and reenter the atmosphere prematurely. This posed a problem for the designers of the GOCE...

NASA researchers are about to fly off on a campaign that will take them into the heart of thunderstorm country. The Deep Convective Clouds and Chemistry (DC3) field campaign will use an airport in Salina, Kan., as a base to explore the impact of large thunderstorms on the concentration of ozone and other substances in the upper troposphere. The campaign is being led by the National Center for Atmospheric Research in Boulder, Colorado, and is funded by the National Science Foundation (NSF)...

MOUNTAIN VIEW, Calif., May 8, 2012 /PRNewswire/ -- Los Gatos Research (LGR), the leader in precision trace gas analyzers, has received an order for five more of the company's unique N2O/CO (nitrous oxide/carbon monoxide) trace gas analyzers from the California Air Resources Board (CARB). These particular instruments (part of LGR's acclaimed Enhanced Performance series) deliver extremely stringent performance specifications, including better than fifty parts-per-trillion...

A NASA Weather 'Eye in the Sky' Marks 10 Years
2012-05-04 13:27:15

For 10 years, it has silently swooped through space in its orbital perch 438 miles (705 kilometers) above Earth, its nearly 2,400 spectral "eyes" peering into Earth's atmosphere, watching. But there's nothing alien about NASA's Atmospheric Infrared Sounder, or AIRS, instrument, a "monster" of weather and climate research that celebrates its 10th birthday in orbit May 4. AIRS, built by BAE Systems, Boston, under the direction of NASA's Jet Propulsion Laboratory, Pasadena, Calif., is one of...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Important things to know when it comes to weather are the terms that a meteorologist uses on the television, radio or on a weather website.  The first term is Return flow. Sometimes you will hear a meteorologist use this term. The best way to understand this is to look at a weather map. When you see a High pressure center which is the blue H, look to the western side of that high pressure. This is where the warm moist air starts moving from the south back towards the north, which is why it...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

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...
