Research Aircraft Observations of Atmospheric Ozone Merged with Topography & High-resolution Weather Forecast Model
Kenneth P. Bowman and Cameron Homeyer, Texas A&M University
This figure shows the results of an atmospheric research aircraft flight. The Rocky Mountains are on the left, Lake Michigan is in the upper right, and the colored line is the flight path. The colors along the track show the atmospheric ozone concentration. The transparent blue surface shows the jet stream, and the purple surface is the boundary between the troposphere and stratosphere.

Magnetron Cavity
Christine Roark, Tech-X Corporation
The image shows results from a simulation using our in house software, VORPAL, which was used to simulate a magnetron. The coloration of the cavity comes from a projection of the magnetic field onto its walls. The particles are colored by density where more dense regions are darker in color.

Arctic Sea Ice Extent
Matt Savoie, National Snow and Ice Data Center
This image shows the minimum sea ice extent for 2008 (in white), superimposed on the record minimum extent, recorded in 2007 (in dark gray). Areas with sea ice during both years are shown in light grey. The orange line represents the median ice extent for the years 1979-2000. This image is a perspective representation of the current state of Arctic sea ice.

Global Winds
Michael Galloy, Tech-X Corporation
This image show a line-integral convolution (LIC) representation of the global NASA wind velocity data. The image shows a combination of LIC output with the earth image. Dark colors represent low velocity winds, and lighter colors reflect higher velocity winds.

Backdrop for a Simulation of Satellite Antenna Performance
Don J. Hinshilwood, The Aerospace Corporation
The image is a screenshot of a sample backdrop for a simulation of satellite antenna performance. The simulation will overlay antenna coverage patterns and other information on the backdrop.

VORPAL Simulation of the Wakefields Induced by Electrons in a Radio-frequency Cavity
Michael Galloy and Christine Roark, Tech-X Corporation
This image shows a current carried by electrons (colored spheres) traveling through these complex superconducting structures leads to the emission of an electromagnetic field. The thin wires trace the magnetic field structure, showing that divergence freeness of the magnetic field.
