Latest Earth's atmosphere Stories
A NASA-led research team has expanded the growing global armada of remote sensing satellites capable of studying carbon dioxide, the leading greenhouse gas driving changes in Earth's climate.
Kudzu, an invasive vine that is spreading across the southeastern United States and northward, is a major contributor to large-scale increases of the pollutant surface ozone.
Let a bunch of fluorine atoms get together in the molecules of a chemical compound, and they're like a heavy metal band at a chamber music festival.
Icelandâ€™s volcanic eruption, which grounded air traffic for days, may provide rare clues as to how flights encourage climate change, adding to evidence from a ban on US flights after the World Trade Center attacks on September 11, 2001
Current observational tools cannot account for roughly half of the heat that is believed to have built up on Earth in recent years, according to a "Perspectives" article in this week's issue of Science.
Exposure to an increased level of air pollutants, especially nitrogen dioxide, has been associated with lower likelihoods of successful pregnancy among women undergoing in vitro fertilization, according to a team of fertility researchers.
WASHINGTON, April 8 /PRNewswire-USNewswire/ -- NASA has successfully completed the first science flight of the Global Hawk unpiloted aircraft system over the Pacific Ocean.

Pollution originating in Asia is being lifted into the stratosphere during monsoon season, where it then circles around the globe for several years.
A study published this week in the journal Proceedings of the National Academy of Sciences (PNAS) provides new information about the rates at which three of the most powerful greenhouse gases are destroyed by a chemical reaction that takes place in the upper atmosphere.
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...
