High Resolution 2-D Numerical Simulation of Emergence of Magnetic Flux Through the Solar Atmosphere
This series of animations (animations 107, 1416, 1417, and 1418) show sheets of magnetic flux undergoing velocity perturbations. The conditions for each simulation are outlined within the video.
A 3-Dimensional Model of the Magnetosphere (WMS)
The earths magnetosphere protects the earth from high-energy charged particles coming from the sun. Some charged particles are deflected by the magnetosphere, while others become trapped and produce the aurora. This presentation shows a 3-dimensional model of the magnetosphere. The features that it highlights are flat ribbons representing the paths of charged particles deflected by the magnetosphere, triangular ribbons representing magnetic field lines, and colored surfaces representing constant

NDVI in North America for August 1993, based off data collected over the 1981-2000 time frame.
Ozone Measurements from 2000 through 2003 (WMS)
This visualization shows the total ozone concentrations for the Earth from January 1, 2000 through December 31, 2003, as measured by the Toms instrument on the Earth Probe satellite. Low ozone (less than 200 Dobson units) is depicted as regions of dark blue, with high ozone (greater that 330 Dobson units) depicted as yellow and red. The most visible and dynamic feature of the ozone distribution is the ozone hole that forms over Antarctica during September of each year. The amount of ozone in the

The History of Public Health
In the History of Public Health we will examine the historical experience of health and illness from a population perspective. This material seeks to reveal how the organization of societies facilitates or mitigates the production and transmission of disease. It also asks how do populations and groups of individuals go about securing their health? One key theme is the medical management of space in one form or another - from the public space of the environment through institutional spaces such a
Introduction to Economics
