HIAPER Pole to Pole Observations (HIPPO) - Multimedia Gallery
NCAR & UCAR News Center (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.

Regional Climate Models: A Critical Adaptation Tool for Communities and Industry - Part 1: Introduction
Michael Oppenheimer (Princeton University) (13 Minutes)
Part 1 of 4: The impacts of climate change and climate variability have become increasingly problematic worldwide. These can vary widely with location and ecosystem, affecting both public and private sectors, often in unforeseen ways. As policymakers at national, regional, state and local levels grapple with how to mitigate and adapt to a changing and variable climate, industries must also prepare for and adapt to environmental and weather exigencies. New techniques in climate modeling will enable stakeholders to better predict impacts and prepare for them in a cost-effective way. The purpose of this briefing was to explore the knowledge generated by advanced regional climate modeling, cutting-edge modeling techniques, and the implications for corporate decision makers and regional policymakers. In Part 1 Oppenheimer introduces the key points of the briefing.

The Perlan Project and the Future of High Altitude Soaring
Einar K. Enevoldson (The Perlan Project) (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.

The role of atmospheric rivers in extreme precipitation on the U.S. West Coast: Recent developments on monitoring and short-term prediction
F. Martin Ralph (NOAA) (57 minutes)
Ralph discusses atmospheric rivers as a key phenomenon in the global water vapor budget and in extreme rainfall events. Heavy precipitation events are difficult to predict, but advances in modeling, observations, and physical understanding are emerging and helping to create tools for forecasters. Reanalysis data, unmanned flights, and field experiments are being planned to explore key scientific questions and to improve predictions.

The Discovery of the Solar Wind: A 2000 Year History
Eugene Parker (University of Chicago) (57 minutes)
Many concepts essential for recognition of the hydrodynamic expansion process of the solar corona have developed over the past three millennia. Among these are several controversial ideas and erroneous concepts, including, says Parker, the still widely stated idea that a cloud of collisionless particles cannot be treated as a hydrodynamic fluid. For Parker, the outstanding problem facing space science and solar wind theory is the illusive heating of the solar corona associated with the various phases of the wind.

Space Plasmas, Magnetic Fields, the Principles of Physics, and Human Nature
Eugene Parker (University of Chicago) (68 minutes)
Parker examines diverse and contrary theories regarding magnetic activity that are based on personal convictions about electric currents and fields. Forgotten, he says, is the fact that there can be no significant electric field in the moving frame of reference of ionized gas. This curious psychological aversion to the conclusions dictated by the basic principles of physics is noteworthy, in Parker's view.
