Einar K. Enevoldson (The Perlan Project) Jun. 18, 2009
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.

Scientific and Observational Challenges in Mesoscale and Convective-Scale Meteorology
(58 minutes, click title to view .mov with QuickTime)
Bluestein reviews mesoscale observing systems and what they can and cannot do. Challenges range from increasing coverage, frequency of observation, and spatial resolution to integrating measurements. With the vast amounts of data produced, one of the most important challenges is rapid quality control and editing.

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.
Randolph "Stick" Ware (NCAR, ESSL, MMM, Radiometrics Corporation) Sep. 28, 2008
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.

Jose Luis Jimenez (CIRES, University of Colorado Boulder) Oct. 17, 2007
Aerosol Mass Spectrometric Characterization of Organic Particles: New Techniques and Field Results
(51 minutes)
Jimenez discusses the use of aerodyne aerosol mass spectrometers for the characterization of organic aerosols. Jimenez summarizes recent spectrometer developments and presents results from several recent field campaigns in the United States and Mexico. He compares secondary organic aerosols and total organic aerosols derived from currently used models to real-world aerosols. | Abstract
Vanda Grubisic (Desert Research Institute) Oct. 03, 2007
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. | News Release
