Brightly-lit Cowboys Stadium during Sunday's Super Bowl XLV may symbolize one of the hottest new pieces of scientific intelligence about air pollution: Researchers have discovered "” in a classic case of scientific serendipity "” that the bright light from sports stadiums and urban street lights may boost daytime levels of ozone, a key air pollutant in many heavily populated areas. That's among the topics included in a broader article about the chemistry of air pollution in the...

The magnitude of climate change during Earth's deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes. The study, by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl, will appear as a "Perspectives" piece in this week's issue of the journal Science. Building on recent research, the study examines the relationship between global temperatures and high...

A team led by scientists at the National Oceanography Centre have measured the air-sea exchange of carbon dioxide in the open ocean at higher wind speed than anyone else has ever managed. Their findings are important for understanding how interactions between the oceans and the atmosphere influence climate. "Evaluating the factors influencing the transfer of gases such as carbon dioxide between the atmosphere and the ocean is needed for a full understanding of Earth's climate system,"...

A mysterious high-altitude layer of sulphur dioxide discovered by ESA's Venus Express has been explained. As well as telling us more about Venus, it could be a warning against injecting our atmosphere with sulphur droplets to mitigate climate change. Venus is blanketed in sulphuric acid clouds that block our view of the surface. The clouds form at altitudes of 50"“70 km when sulphur dioxide from volcanoes combines with water vapor to make sulphuric acid droplets. Any remaining...

U.S. and British meteorologists said on Monday that not only is Earth's surface warming, but the troposphere is heating up also. The scientists found that warming in this key atmospheric layer was occurring, just as many researchers expected as more greenhouse gases build up and trap heat close to the Earth. This study put to rest a controversy that began 20 years ago when a 1990 scientific report raised questions about whether the troposphere was warming, even as Earth's surface...

Nine years after beginning its unprecedented look at the gateway between Earth's environment and space, not to mention collecting more data on the upper atmosphere than any other satellite, NASA's Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission has been extended again. Before the launch of TIMED, the mesosphere and lower thermosphere/ionosphere -- which help protect us from harmful solar radiation -- had been one of the least explored and understood regions of our...

New space research published this week (Thursday 21 October) in the journal Nature, has settled decades of scientific debate. Researchers from the University of California (UCLA) and British Antarctic Survey (BAS) have found the final link between electrons trapped in space and the glow of light from the upper atmosphere known as the diffuse aurora. The research will help us understand 'space weather', with benefits for the satellite, power grid and aviation industries, and how space storms...

Pyrocumulonimbus is the fire-breathing dragon of clouds. A cumulonimbus without the "pyre" part is imposing enough -- a massive, anvil-shaped tower of power reaching five miles (8 km) high, hurling thunderbolts, wind and rain. Add smoke and fire to the mix and you have pyrocumulonimbus, an explosive storm cloud actually created by the smoke and heat from fire, and which can ravage tens of thousands of acres. And in the process, "pyroCb" storms funnel their smoke like a chimney into Earth's...

Using data from several research satellites, scientists will spend the next three years trying to understand the climate impacts of about 770 million tons of dust carried into the atmosphere every year from the Sahara Desert. Some Saharan dust falls back to Earth before it leaves Africa. Some of it streams out over the Atlantic Ocean or Mediterranean Sea, carried on the wind as far away as South America and the southeastern U.S. All of it has an as-yet unmeasured impact on Earth's energy...

Imagine devices that capture electricity from the air "” much like solar cells capture sunlight "” and using them to light a house or recharge an electric car. Imagine using similar panels on the rooftops of buildings to prevent lightning before it forms. Strange as it may sound, scientists already are in the early stages of developing such devices, according to a report at the 240th National Meeting of the American Chemical Society. "Our research could pave the way for turning...

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 -- 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...
