NASA : NASA Airborne Campaigns Tackle Climate Questions from Africa to Arctic
Hola amigos: A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos informa sobre los avances de la investigación que está haciendo alrededor de todo el mundo con su Proyecto: Contaminación de la Atmósfera y el cambio climático como consecuencia como afecta a la vida de la Tierra, esta vez el avión : NASA’s DC-8, volará sobre el África.
NASA nos dice: "NASA hará : Cinco nuevas campañas de campo en el aire llevará a los cielos a partir de 2015 para investigar en un lago alcance cómo la contaminación del aire el calentamiento de las aguas oceánicas, y los incendios en África afecta a nuestro clima.......
Estos estudios en varios procesos del sistema Tierra-no del todo comprendidas fueron seleccionadas de forma competitiva en el marco de proyectos de clase Venture Tierra de la NASA. Cada proyecto es financiado con un costo total de no más de $ 30 millones en cinco años. Esta financiación incluye el desarrollo inicial, campañas de campo y análisis de datos.......

The DC-8 airborne laboratory is one of several NASA aircraft that will fly in support of five new investigations into how different aspects of the interconnected Earth system influence climate change.
Five new NASA airborne field campaigns will take to the skies starting in 2015 to investigate how long-range air pollution, warming ocean waters, and fires in Africa affect our climate.
These studies into several incompletely understood Earth system processes were competitively-selected as part of NASA’s Earth Venture-class projects. Each project is funded at a total cost of no more than $30 million over five years. This funding includes initial development, field campaigns and analysis of data.
This is NASA’s second series of Earth Venture suborbital investigations -- regularly solicited, quick-turnaround projects recommended by the National Research Council in 2007. The first series of five projects was selected in 2010.
"These new investigations address a variety of key scientific questions critical to advancing our understanding of how Earth works," said Jack Kaye, associate director for research in NASA's Earth Science Division in Washington. “These innovative airborne experiments will let us probe inside processes and locations in unprecedented detail that complements what we can do with our fleet of Earth-observing satellites.”
The five selected Earth Venture investigations are:
Atmospheric chemistry and air pollution– Steven Wofsy of Harvard University in Cambridge, Massachusetts, will lead the Atmospheric Tomography project to study the impact of human-produced air pollution on certain greenhouse gases. Airborne instruments will look at how atmospheric chemistry is transformed by various air pollutants and at the impact on methane and ozone which affect climate. Flights aboard NASA’s DC-8 will originate from the Armstrong Flight Research Center in Palmdale, California, fly north to the western Arctic, south to the South Pacific, east to the Atlantic, north to Greenland, and return to California across central North America.
Ecosystem changes in a warming ocean– Michael Behrenfeld of Oregon State University in Corvallis, Oregon, will lead the North Atlantic Aerosols and Marine Ecosystems Study, which seeks to improve predictions of how ocean ecosystems would change with ocean warming. The mission will study the annual life cycle of phytoplankton and the impact small airborne particles derived from marine organisms have on climate in the North Atlantic. The large annual phytoplankton bloom in this region may influence the Earth’s energy budget. Research flights by NASA’s C-130 aircraft from Wallops Flight Facility, Virginia, will be coordinated with a University-National Oceanographic Laboratory System (UNOLS) research vessel. UNOLS, located at the University of Rhode Island’s Graduate School of Oceanography in Narragansett, Rhode Island, is an organization of 62 academic institutions and national laboratories involved in oceanographic research.
Greenhouse gas sources– Kenneth Davis of Pennsylvania State University in University Park, will lead the Atmospheric Carbon and Transport-America project to quantify the sources of regional carbon dioxide, methane and other gases, and document how weather systems transport these gases in the atmosphere. The research goal is to improve identification and predictions of carbon dioxide and methane sources and sinks using spaceborne, airborne and ground-based data over the eastern United States. Research flights will use NASA’s C-130 from Wallops and the UC-12 from Langley Research Center in Hampton, Virginia.
African fires and Atlantic clouds– Jens Redemann of NASA’s Ames Research Center in Mountain View, California, will lead the Observations of Aerosols above Clouds and their Interactions project to probe how smoke particles from massive biomass burning in Africa influences cloud cover over the Atlantic. Particles from this seasonal burning that are lofted into the mid-troposphere and transported westward over the southeast Atlantic interact with permanent stratocumulus “climate radiators,” which are critical to the regional and global climate system. NASA aircraft, including a Wallops P-3 and an Armstrong ER-2, will be used to conduct the investigation flying out of Walvis Bay, Namibia.
Melting Greenland glaciers– Josh Willis of NASA’s Jet Propulsion Laboratory in Pasadena, California, will lead the Oceans Melting Greenland mission to investigate the role of warmer saltier Atlantic subsurface waters in Greenland glacier melting. The study will help pave the way for improved estimates of future sea level rise by observing changes in glacier melting where ice contacts seawater. Measurements of the ocean bottom as well as seawater properties around Greenland will be taken from ships and the air using several aircraft including a NASA S-3 from Glenn Research Center in Cleveland, Ohio, and Gulfstream III from Armstrong.
Seven NASA centers, 25 educational institutions, three U.S. government agencies and two industry partners are involved in these Earth Venture projects. The five investigations were selected from 33 proposals.
Earth Venture investigations are part of NASA's Earth System Science Pathfinder program managed at Langley for NASA’s Science Mission Directorate in Washington. The missions in this program provide an innovative approach to address Earth science research with periodic windows of opportunity to accommodate new scientific priorities.
NASA monitors Earth's vital signs from land, sea, air and space with a fleet of satellites and ambitious airborne and surface-based observation campaigns. With this information and computer analysis tools, NASA studies Earth's interconnected systems to better see how our planet is changing. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.
