NCAR & UCAR Visuals & Multimedia in the News en-us Video, animations, and photos illustrating atmospheric, Earth, and solar research, field projects, and other news. Sunspots in 3D - Multimedia Gallery For the first time, NCAR scientists and colleagues have modeled the complex structure of sunspots in a comprehensive 3D computer simulation, giving scientists their first glimpse below the visible surface, or photosphere, of the Sun to understand sunspots' underlying physical processes. 2009-09-08 00:00:00.0 Thermosphere Visuals - Multimedia Gallery Even though emissions of carbon dioxide warm the lower atmosphere, they have the opposite effect on the upper atmosphere. The reason has to do with the difference in density. 2009-09-03 00:00:00.0 World's Largest Tornado Experiment - Multimedia Gallery The largest and most ambitious tornado study in history began May 10, 2009, as dozens of scientists deployed radars and other ground-based instruments across the Great Plains to gain a better understanding of these often deadly weather events. 2009-05-04 00:00:00.0 HIAPER Pole to Pole Observations (HIPPO) - Multimedia Gallery HIPPO is a three-year field project to make the most extensive airborne sampling of carbon dioxide and other greenhouse gases in the atmosphere to date, from the Arctic to the Antarctic. Study results will help scientists understand the behavior of these gases in the atmosphere and lead to improved predictions about climate change. 2009-01-29 00:00:00.0 Bluefire Supercomputer - Multimedia Gallery NCAR has taken delivery of a new IBM supercomputer that will advance research into severe weather and the future of Earth's climate. The supercomputer, a Power 575 Hydro-Cluster, is the first in a highly energy-efficient class of machines to be shipped anywhere in the world. 2008-05-19 00:00:00.0 MOPITT Instrument - Multimedia Gallery MOPITT (Measurements of Pollution in the Troposphere) is an instrument flying on NASA's EOS Terra spacecraft. NCAR scientists and their international colleagues developed and run MOPITT to measure the global distributions of carbon monoxide (CO) and methane (CH4) in the troposphere. CO also serves as a tracer for other kinds of air pollution. 2008-04-30 00:00:00.0 Weather Modification - Multimedia Gallery Commercial operators, governments, and academic researchers worldwide are engaging in cloud seeding and other weather modification projects to try to influence local conditions. NCAR scientists and their colleagues are investigating efforts to build up wintertime snowpack in the western United States and bring more rain to drought-stricken regions around the world. 2008-04-30 00:00:00.0 Solar Telescope Reaches 120,000 Feet on Jumbo-Jet-Sized Balloon - Multimedia Gallery The Sunrise project test clears the way for long-duration polar balloon flights beginning in 2009. These flights will capture unprecedented details of the Sun's surface. This multimedia gallery offers photographs, animations, and videos. 2007-10-23 00:00:00.0 Scientists Close in on Missing Carbon Sink; Northern Forests Less Effective than Expected - Multimedia Gallery Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought. 2007-06-21 00:00:00.0 Sun's Deep Interior Revealed by New Computer Model; Research Provides Clues to the Inner Dynamics of Stars - Multimedia Gallery A new computer model simulates convection patterns in the deep interior of the Sun in unprecedented detail. The patterns, known as giant cells, play a critical role in solar variability, influencing magnetic storms that take aim at Earth. 2007-05-28 00:00:00.0 Arctic Ice Retreating More Quickly than Computer Models Project - Multimedia Gallery Arctic sea ice is melting at a significantly faster rate than projected by even the most advanced computer models, a new study concludes. The research, by scientists at NCAR and the University of Colorado's National Snow and Ice Data Center, shows that the Arctic's ice cover is retreating more rapidly than estimated by any of the 18 computer models used by the Intergovernmental Panel on Climate Change (IPCC) in preparing its 2007 assessments. 2007-04-30 00:00:00.0 Scientists to Track Impact of Asian Dust and Pollution on Clouds, Weather, Climate Change - Multimedia Gallery Using the nation's newest and most capable aircraft for environmental research, scientists have launched PACDEX, a far-reaching field project to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. 2007-04-18 00:00:00.0 Understanding Climate Change - Multimedia Gallery The year 2007 was significant for scientists, policymakers, and citizens investigating climate change and its impact on our planet's future. That year marked the release of a major report produced through global cooperation, the free exchange of ideas, and thorough scientific investigation. This multimedia gallery supports discussion of the report and current climate research. 2007-02-15 00:00:00.0 Innovative Satellite System Proves Its Worth with Better Weather Forecasts, Climate Data - Multimedia Gallery A set of six microsatellites, launched in April 2006, is probing the atmosphere in ways that have been impossible with previous observing systems. COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate) can boost the accuracy of forecasts of hurricane behavior, significantly improve long-range weather forecasts, and monitor climate change with unprecedented accuracy. 2006-12-11 00:00:00.0
