MOPITT Instrument - Multimedia Gallery NCAR MOPITT team (illustrations and videos) 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. | News Release |

Atmospheric Pollution from Megacities Sasha Madronich (ACD) (55 minutes) Air pollution from megacities not only affects local air quality, but spills over into surrounding regions, possibly to the entire globe. There are consequences for human health, cultivated and natural ecosystems, visibility, atmospheric energy budgets, weather modification, and climate. He points out areas of uncertainty where further research is needed. Recent studies show that dilution is not a solution. |

The Story of Ozone in Our Atmosphere: A Success Story Guy Brasseur (ESSL) (58 minutes) Brasseur provides a historical perspective on the discovery of the chemical nature of this gas and its ability to protect the biosphere from harmful ultraviolet solar radiation. It took decades for scientists to understand how ozone is formed and how it is destroyed. Brasseur discusses the role of observations, laboratory studies, and modeling in successfully addressing the problem of the Antarctic ozone hole, which was created by the use of industrially manufactured chlorofluorocarbons. The efforts to reduce ozone depletion have also had a protective effect on the climate, making this is a story of success for both the scientific community and policymakers. |

The Energy Challenge of Climate Change: More Urgent Than We Thought Tom Wigley (NCAR), Jae Edmonds (Pacific Northwest National Laboratory, University of Maryland) (32 minutes) In this congressional briefing Wigley notes that the amount of carbon-free energy required to stabilize CO2 concentrations has been built into no-climate-policy scenarios. These assumed changes may be unrealistic in the face of rapid development in Asia. According to Edmonds, stabilizing CO2 concentrations at 550 ppm will require new science and technology to reduce the cost of such an effort. | GTSP Report |

T-REX: Terrain-induced Rotor Experiment, March-April 2006 Vanda Grubisic (Desert Research Institute) (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.

Space Weather: New Prospects for a Technology-Based Global Economy Tom Bogdan (NOAA Space Weather Prediction Center) (50 minutes) Space weather traces its origins to the Sun's dynamic variability. It is driven by the combined actions of rotation, turbulent convection, and magnetic fields. Solar weather follows a quasi-11-year cycle and can be correlated with auroral activity. Bogdan lists three varieties of solar weather that are analogous to Earth's tornadoes, hurricanes, and wind. Solar weather can be forecast using the same kinds of tools that meteorologists use and is important to a growing client base. Our rapidly evolving high-tech global economy has become increasingly vulnerable to the effects of space weather on the health of airline workers, air transportation, satellite communications, warfare, fossil fuel extraction, power generation, human exploration, and commercial utilization of space. |
