Atmosphere

The gas composition of Earth's atmosphere is changing, as are its wind circulation and severity of major storms.

Top layers of the Earth's atmosphere leading to space. Atmospheric gases scatter blue light more than other wavelengths, giving Earth a blue halo when seen from space.

State of the Climate in 2011 Last Updated on 2012-07-11 00:00:00 Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30 year average, according to the 2011 State of the Climate report released online by the National Oceanic and Atmospheric Administration (NOAA). Back-to-back La Niñas cooled globe and influenced extreme weather in 2011 NOAA-led report examines climate conditions experienced around the world The lead character of the 2011 climate story was a double dip La Niña, which chilled the Pacific at the start and end of the year. Many of the 2011 seasonal climate patterns around the world were consistent with common side effects of La Niña. More information. Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30 year average, according to the 2011 State of the Climate report released online today by NOAA. The...

American Meteorological Society Last Updated on 2011-11-27 00:00:00 The American Meteorological Society (AMS) promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. The AMS offers an array of undergraduate scholarships and graduate fellowships to students pursuing careers in the atmospheric and related oceanic and hydrologic sciences. It also administers two professional certification programs, the Certified Broadcast Meteorologist (CBM) and Certified Consulting Meteorologist (CCM) programs.[1][2] The AMS has a staff of 50 people headquartered in Boston, Massachusetts and also has another office in Washington, DC. History of the AMS The American Meteorological Society was founded in 1919 by Charles Franklin Brooks of the Blue Hill Observatory in Milton, Massachusetts. Its initial membership... More »
Scientific Assessment of Ozone Depletion: 2010 Last Updated on 2011-04-06 00:00:00 Scientific Assessment of Ozone Depletion: 2010 The Scientific Assessment of Ozone Depletion: 2010 Record stratospheric ozone loss in the arctic in spring of 2011 Depletion of the ozone layer- the shield that protects life on Earth from harmful levels of ultraviolet rays - has reached an unprecedented level over the Arctic this spring because of the continuing presence of ozone-depleting substances in the atmosphere and a very cold winter in the stratosphere. The stratosphere is the second major layer of the Earth’s atmosphere, just above the troposphere. The record loss is despite an international agreement which has been very successful in cutting production and consumption of ozone destroying chemicals. Because of the long atmospheric lifetimes of these compounds it will take several decades before their concentrations are back down to pre-1980 levels, the... More »
Oil Spill Air Pollution Last Updated on 2011-03-14 00:00:00   ?Main Image: Deepwater Horizon oil spill as seen from a NOAA research  airrcraft, June 2010. Credit: David Valentine, University of California Santa Barbara. Insights from Oil Spill Air Pollution Study have Applications Beyond Gulf  During a special airborne mission to study the air-quality impacts of the BP Deepwater Horizon oil spill, June 2010, NOAA researchers discovered an important new mechanism by which air pollution particles form. Although predicted four years ago, this discovery now confirms the importance of this pollution mechanism and could change the way urban air quality is understood and predicted. The NOAA-led team showed that although the lightest compounds in the oil evaporated within hours, it was the heavier compounds, which took longer to evaporate, that contributed most to the formation of air pollution particles downwind....
