Image 1 - Venus Weather Not So Boring After All
2011-09-28 04:26:59

At first glance, a weather forecaster for Venus would have either a really easy or a really boring job, depending on your point of view. The climate on Venus is widely known to be unpleasant -- at the surface, the planet roasts at more than 800 degrees Fahrenheit under a suffocating blanket of sulfuric acid clouds and a crushing atmosphere more than 90 times the pressure of Earth's. Intrepid future explorers should abandon any hope for better days, however, because it won't change much....

   ESA´s Envisat observation satellite yesterday completed its 50,000th circuit of Earth — travelling 2.25 billion km since its launch nearly a decade ago. Envisat orbits our planet every 100 minutes, speeding along at more than seven kilometers per second. During this milestone spin around the world on 22 September, the satellite passed from the Arctic to the Antarctic, catching glimpses of northern Greenland and New Zealand. Launched on 28 February 2002, the...

Preliminary research on Fusarium, a group of fungi that includes devastating pathogens of plants and animals, shows how these microbes travel through the air. Researchers now believe that with improvements on this preliminary research, there will be a better understanding about crop security, disease spread, and climate change. Engineers and biologists are steering their efforts towards a new aerobiological modeling technique, one they think may assist farmers in the future by providing an...

Researchers Produce First Map Of Greenhouse Gas In The Atmosphere
2011-09-08 12:36:40

  Researchers say that a series of pole-to-pole science flights has produced the first global portrait of the distribution of greenhouse gases in the atmosphere. Research flights were conducted by the National Center for Atmospheric Research (NCAR)from the Arctic to the Antarctic.  The three-year series of flights enabled researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth's climate, according to an NCAR...

By Ann Perry, USDA/ARS U.S. Department of Agriculture (USDA) scientists have produced the first detailed data on how large-scale dairy facilities contribute to the emission of greenhouse gases. This research was conducted by Agricultural Research Service (ARS) scientists at the ARS Northwest Irrigation and Soils Research Laboratory in Kimberly, Idaho. ARS is USDA's principal intramural scientific research agency, and these studies support the USDA priority of responding to climate change. ARS...

Australian research institute Commonwealth Scientific and Industrial Research Organization (CSIRO) launched a new website on Monday that allows Internet users to monitor greenhouse gas emissions. The site was developed so people can see how climate-warming gases have increased as a result of human activities. "The measurements testify to a steady rise in carbon dioxide concentrations in the Earth's atmosphere, mainly caused by the burning of fossil fuels and deforestation," CSIRO scientist...

How do instruments end up on satellites orbiting the Earth? For many of them, long before they are ever launched into space, they are tested from NASA airplanes. One of the objectives of the NASA Airborne Science Program is to test new instruments in space-like environments. Testing future satellite instruments from airplanes is the next best thing to actually testing them in space. Over the past three weeks, a team from NASA's Goddard Space Flight Center, Greenbelt, Md., led by Bill Heaps...

By Steve Koppes, University of Chicago Geochemist Albert Colman follows trail from Kamchatka microbes into the history of Earth's atmosphere. Exotic bacteria that do not rely on oxygen may have played an important role in determining the composition of Earth's early atmosphere, according to a theory that UChicago researcher Albert Colman is testing in the scalding hot springs of a volcanic crater in Siberia. He has found that bacteria at the site produce as well as consume carbon monoxide, a...

Accounting for wavelength effects will likely improve climate modelsAtmospheric scientists trying to pin down how clouds curb the amount of sunlight available to warm the earth have found that it depends on the wavelength of sunlight being measured. This unexpected result will help researchers improve how they portray clouds in climate models.Additionally, the researchers found that sunlight scattered by clouds "” the reason why beachgoers can get sunburned on overcast days "” is...

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 -- 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...
