Latest Earth's atmosphere Stories
WASHINGTON, April 21, 2011 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet's axis varies.
A British-based team of astronomers has discovered carbon monoxide gas in the atmosphere of Pluto, after a worldwide search lasting for nearly two decades.
One of the primary science goals of MESSENGER is to study Mercuryâ€™s very thin atmosphere, or exosphere.
High up in the sky near the poles some 50 miles above the ground, silvery blue clouds sometimes appear, shining brightly in the night.
Scientists have known for decades that black carbon aerosols add to global warming.
Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland.
ESAâ€™s Envisat satellite has measured record low levels of ozone over the Euro-Atlantic sector of the northern hemisphere during March.
Differences in air pressure over the North Atlantic have meant that the last two winters in Gothenburg, Sweden, have been extremely cold.
An assessment report to be released this week by the United Nations Environment Program and the World Meteorological Organization shows that reducing emissions of two common air pollutants -- black carbon and gases integral to the production of ground-level ozone -- could slow the rate of climate change markedly over the next half-century.
LEHIGH VALLEY, Pa., Feb. 16, 2011 /PRNewswire/ -- Air Products (NYSE: APD) has been selected by Solar Atmospheres, Inc., the largest commercial vacuum heat treating company in North America, to provide industrial gases for its newest plant in Fontana, Calif.
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 -- 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 -- 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...
