Title	ViSBARD: The Wind from the Sun
Abstract	The ViSBARD (Visual System for Browsing, Analysis, and Retrieval of Data) analysis package has an option to propagate measurements carried by the solar wind. In this visualization created from ViSBARD screenshots, three spacecraft ahead of the Earth's bow shock measure the magnetic field as it is carried by the solar wind towards the Earth. Their positions as projected according to the flow speed are noted with the small glyph (Wind = yellow, Geotail = blue, IMP-8 = green). The spacecraft actually move very little over the time interval shown, but a spatial picture emerges when we use a knowledge of the wind velocity to spread the vectors out according to how they flowed past the point of observation. Arrows on the satellite glyphs indicate the magnitude and direction of the magnetic field while the color also represents the intensity (red being the highest, blue the lowest). As the wind flows, we can rapidly obtain information on the extended geometry of convected structures. The wire-frame at the left is a representation of the Earth's bow shock (about 100 Earth radii across in what is shown) that shows where the Sun's magnetic field would begin to be affected by that the Earth. (The effect of the interaction is not shown.)

Title	THEMIS Orbits: Transitions
Abstract	Between the dayside and nightside phases of the mission, the five spacecraft will conduct orbit change maneuvers over a period of three months. During this visualization, the camera position is locked in GSE coordinates, keeping the Sun to the left. The orbital axis is actually fixed in space but appears to move due to the Earth's motion around the Sun. The dates in this visualization are based on an ephemeris assuming a launch on January 20, 2007. The satellites are represented by the colors: red=P1, green=P2, cyan=P3, blue=P4, magenta=P5.

Polar Visible Aurora: Normal Solar Wind Conditions on November 13, 1999 over the North Pole

Title	Polar Visible Aurora: Normal Solar Wind Conditions on November 13, 1999 over the North Pole
Abstract	On May 11, 1999, the solar wind that blows constantly from the Sun virtually disappeared. Dropping to a small fraction of its normal density and to half its normal speed, the solar wind died down enough to allow physicists to observe particles flowing directly from the Sun's corona to Earth. This severe change in the solar wind also drastically changed the shape of Earth's magnetic field and produced a rare auroral display at Earth's North Pole.

THEMIS Orbits: Nightside Science Configuration

Title	THEMIS Orbits: Nightside Science Configuration
Abstract	In the latter phase of the mission, the five THEMIS spacecraft will travel on five co-aligned elliptical orbits with their apogee on the nightside of the Earth. From there, they will sample the particle and electromagnetic wave environment along the magnetotail. The dates in this visualization are based on an ephemeris assuming a launch date of January 20, 2007. The five satellites are represented by colors: red=P1, green=P2, cyan=P3, blue=P4, magenta=P5

THEMIS Orbits: Dayside Science Configuration

Title	THEMIS Orbits: Dayside Science Configuration
Abstract	In the early part of the mission, the five THEMIS satellites will follow the same orbit single-file. The apogee of the orbit will take the spacecraft just beyond the bowshock of the Earth's magnetosphere. This will enable the satellites to collect data in this region over a short range of time so that the time history can be studied. The dates in this visualization are based on an ephemeris assuming a launch on January 20, 2007. The satellite colors are: red=P1, green=P2, cyan=P3, blue=P4, magenta=P5.

The Magnetosphere - Earth Raises its Shields

Title	The Magnetosphere - Earth Raises its Shields
Abstract	A view of a computer-generated model of the Earth's magnetosphere. Semi-transparent surfaces represent particle density (red is high, blue is low) and silvery tubes represent the magnetic field lines. In this particular model, the solar wind has an ambient density of 8.35 particles/cm^3. The isosurfaces are then red (> 17 particles/cm^3), yellow (> 12 particles/cm^3), green (> 8.6 particles/cm^3) and blue (

Global Surface Wind Speed during Hurricane Frances (WMS)

Title	Global Surface Wind Speed during Hurricane Frances (WMS)
Abstract	The weight of the Earth's atmosphere exerts pressure on the surface of the Earth. This pressure varies from place-to-place and from time-to-time due to surface irregularities, uneven heating of the atmosphere by the sun, and the Earth's rotation. Differences in pressure from place-to-place cause winds to try to flow from high pressure to low pressure regions to even out the differences, but the Earth's rotation and wind friction with the surface act to slow or divert the winds. This animation shows the surface wind speeds for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. The highest, smoothest winds occur over the oceans where there are no surface irregularities to break up the flow, while flows over land tend to be irregular and highly variable. The highest winds occur in Hurricane Frances and Typhoon Songda, but note that the hurricane's wind speeds reduce dramatically when crossing Florida.
