The Perlan Project and the Future of High Altitude Soaring
(58 minutes, click title to view in Real Player or VLC)
After an introduction by Joachim Kuettner, Enevoldson describes the flight he and Steve Fossett took to 51,500 feet above the Andes to establish the feasibility of soaring to 100,000 feet in a specialized sailplane. The sailplane successfully climbed through the tropopause and 17,000 feet into the stratosphere. A new pressurized sailplane capable of soaring to 90,000 feet is now under construction. It will have characteristics that may make it an attractive research platform.

Phone Call to the Extreme - Probing the Depths in the Pacific Ocean
(47 minutes, QuickTime)
GLOBE students ask the crew and scientific team on the R/V Thompson research ship about the logistics and science of their mission. The scientists are studying exotic life forms on the seafloor around hydrothermal vents in the western Pacific. Students from four countries participating in NSF's FLEXE program (From Local to Extreme Environments) posed questions. Includes stills and video of deep sea creatures from a previous mission.

World's Largest Tornado Experiment - Multimedia Gallery
(illustrations and videos)
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.

HIAPER Pole to Pole Observations (HIPPO) - Multimedia Gallery
(teleconference, videos, photos)
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.

The Need for Wind Profile Measurements from Space: Assimilation of Wind Data from the ADM/Aeolus Mission
(47 minutes)
The Atmospheric Dynamics Mission (Aeolus) will provide line-of-sight wind profiles using a Doppler lidar measurement technique. Wind observations are particularly needed in tropical regions and in the midlatitudes. The latter area has implications for our understanding of the processes that govern Arctic warming and the retreat of Arctic sea ice. Additional objectives are aerosol information and cloud properties.

Continuous Temperature, Humidity, and Liquid Profiling
(50 minutes)
WeatherCam, a passive microwave sensor, monitors the tropospheric air temperature, humidity, and liquid structure that defines local weather. These data can improve convection, precipitation, lightning, fog, icing, turbulence, and dispersion nowcasting and forecasting. Ware presents data from the May 2008 Windsor tornado and live displays from emerging international networks.

T-REX: Terrain-induced Rotor Experiment, March-April 2006
(51 minutes)
Grubisic decribes the methodology and results from the second phase of a coordinated effort to explore the structure and evolution of atmospheric rotors (intense low-level horizontal vortices that form along an axis parallel to, and downstream of, a mountain ridge crest) as well as associated phenomena in complex terrain. Results show that a second mountain range promotes wave trapping and nonlinear wave resonance at large distances. Future study will focus on the effects of upstream atmospheric structure.

Arctic Ice Retreating More Quickly than Computer Models Project - Multimedia Gallery
(animations, illustrations)
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.

HIAPER, the NSF/NCAR Gulfstream-V, the Nation's Most Advanced Research Aircraft
(3 minutes)
An introduction to the NSF/NCAR HIAPER aircraft, a modified Gulfstream-V jet. This NSF video describes its maiden research flights for the Terrain-induced Rotor Experiment. During T-REX an international team of 60 researchers gathered data about treacherous whirlwind turbulence, called atmospheric rotors, and the waves of air associated with them.

The Biocomplexity Project - Video Interviews
(45 brief Q&A segments, various times)
Scientists answer questions about climate change and the Biocomplexity Project, which is developing a mid-infrared, laser-based gas sensor system for continuous insitu measurements of 13CO2/12CO2 ratios. The project exploits the latest developments in optical fiber technology and telecommunication lasers.

Measurements of Water Vapor Isotopes from the MIPAS Satellite Instrument
(36 minutes)
The Michelson Interferometer for Passive Atmospheric Sounding instrument measures atmospheric limb emission spectra and allows retrieval of profiles of pressure, temperature, and numerous trace gasses. The presenter explains how the high spectra resolution of MIPAS makes it possible to distinguish among isotopes.
