Turbulent transport in the atmospheric boundary layer: Lidar measurements and Large Eddy Simulation Turbulent transport in the atmospheric boundary layer (ABL) plays a crucial role in emission and deposition of aerosols. Lidar (Light Detection and Ranging) and LES (Large Eddy Simulation) research is presented to elucidate special and general features of turbulent transport in the ABL. A lidar was operated daily during summer 2002 and measured vertical profiles of aerosol backscatter over Baltimore. During a Canadian forest fire smoke episode in Baltimore on July 7, 2002 downward mixing with severe effects on surface PM2.5 concentration could be observed in great detail. |

The Yellowstone hotspot, which powers Yellowstone National Park's geysers and hot springs, produced 142 huge volcanic eruptions during the last 16.5 million years - far more than the 100 previously known blasts, University of Utah geologists found. The cataclysmic explosions - known as "caldera eruptions" - typically generated 250 to 600 times as much volcanic ash as the 1980 eruption of Mount St. Helens in Washington state, and some were up to 2,500 times larger, covering as much as half the continental United States with inches to feet of volcanic ash. |

Groundwater as an Ecosystem Resource Management of groundwater resources has traditionally focused on human needs for domestic, industrial, and agricultural water supply. In recent years, however, there has been an increasing recognition of the importance of the "ecological services" provided by groundwater discharge to streams, wetlands, and lakes. This recognition comes at a time of increasing human demands resulting from population growth, and as expanding urban areas limit rates of groundwater recharge. In the U.S., water shortages have been experienced in both in the arid west and in areas that are generally considered to be water rich such as the Midwest and Florida. While management strategies that allow for temporary overdraft of aquifers may offer an economically efficient option to satisfy human needs, ecosystems that rely on groundwater discharge can be sensitive to even small declines in water levels. Developing groundwater management strategies that meet human needs while protecting critical ecosystems is a delicate balancing act, and requires improved understanding of the relationships between ecosystem function and groundwater hydrology and geochemistry. |

Techniques of Visualization - Examples from the subsurface of the Michigan Basin Visualization of petroleum systems and reservoir data involves visualization techniques applicable to other fields of science. Today's presentation will use subsurface data from the Michigan Basin to demonstrate the visualization capabilities of in-house and commercial pc-based software. Well log tomography, the slicing of subsurface geophysical log curve data in 2D and the 3D modeling of petroleum reservoirs will be two techniques presented. These techniques have the potential for broad application in the geosciences including the areas of atmospheric particle and groundwater remediation visualization. |

Eruptions that shook the world. The consideration of the global effects of large eruptions takes us to the edge of the historic record and beyond. This talk considers what we know about the global environmetal consequences of several very large events: the Laki eruption of 1783, the Tambora event of 1815 and the YTT eruption of Toba (84ka). |

The effect of crystallization process in clouds on atmospheric chemistry and climate Our recent analysis of laboratory data, supported by thermodynamic calculations, suggest that pure supercooled droplets of any type of material must freeze or crystallize from the outside in, rather than from the inside out. This conclusion goes against the standard and classical theory of crystallization kinetics, where the phase change process has always been assumed to initiate inside a droplet volume rather than on its surface. The phase change process in two specific systems of atmospheric importance will be discussed, namely the freezing of supercooled water droplets into ice particles and the crystallization of polar stratospheric solution droplets into hydrates of nitric acid. The implications of this finding for atmospheric chemistry and climate research will be discussed.

This
is a class built around an interdisciplinary seminar series on
Remote Sensing topics. It is meant to give an introduction to this
rapidly developing research field for our students. It is meant
for students in the Minor program in Remote Sensing, which can be
taken by majors in at least 9 departments. It is also of possible
interest to graduate and undergraduate students interested in
remote sensing and related topics.
