            "title": "Dynamic Earth-A New Beginning",
            "description": "The visualization 'Excerpt from \"Dynamic Earth\"' has been one of the most popular visualizations that the Scientific Visualization Studio has ever created.  It's often used in presentations and Hyperwall shows to illustrate the connections between the Earth and the Sun, as well as the power of computer simulation in understanding those connections.There is one part of this visualization, however, that has always seemed a little clumsy to us.  The opening shot is a pullback from the limb of the sun, where the sun is represented by a movie of 304 Angstrom images from the Solar Dynamics Observatory (SDO).  It is difficult to pull back from the limb of a flat sun image and make the sun look spherical, and the problem was made more difficult because the original sun images were in a spherical dome show format.  As a result, the pullback from the sun showed some odd reprojection artifacts.The best solution to this issue was to replace the existing pullout with a new one, one which pulled directly out from the center of the solar disk.  For the new beginning, we chose a series of SDO images in the 171 Angstrom channel that show a visible coronal mass ejection (CME) in the lower right corner of the solar disk.  Although this is not the specific CME that is seen affecting Venus and Earth later in this visualization, its presence links the SDO animation  thematically to the later solar storm.  The SDO images were also brightened considerably and tinted yellow to match the common perception of the Sun as a bright yellow object (even though it is actually white).Please go to the original version of this visualization to see the complete credits and additional details. || ",

            "title": "Dynamic Earth Dome Show - Biosphere",
            "description": "This visualization was a prototype affiliated with the 'Dynamic Earth', an Earth science planetarium show. The visualization shows the global biosphere and NDVI from the SeaWiFS instrument with MODIS ice and snow overlayed.The images were rendered using a fish eye technique so that they would project properly onto a planetarium dome.Earth scientists are able to measure many of the Earth's 'vital signs', and just like a doctor measures our vital signs to see how healthy we are. Scientists will use these measurements of the Earth to better understand how the Earth functions, how the different systems on Earth interact and how those interactions have set the stage upon which life flourishes. The visualization shows a timeseries of images of SeaWiFS Global Biosphere - the ocean's long-term average phytoplankton chlorophyll concentration acquired between September 1997 and September 2007 combined with the SeaWiFS-derived Normalized Difference Vegetation Index over land. On land, the dark greens show where there is abundant vegetation and tans show relatively sparse plant cover. In the oceans, red, yellow, and green pixels show dense phytoplankton blooms, those regions of the ocean that are the most productive over time, while blues and purples show where there is very little of the microscopic marine plants called phytoplankton. Remote sensing, especially using satellite-mounted colour scanners (SeaWiFS and similar platforms), is advocated for broad-based monitoring of chlorophyll once appropriate algorithms have been developed and proved. The concentration of the photosynthetic pigment chlorophyll a (referred to as chlorophyll) in marine waters is a proven indicator of the biomass of phytoplankton, the organisms that constitute the base of the marine food web. Fluorometry provides an estimate of chlorophyll levels in sea water and thus an estimate of primary productivity in the upper part of the water column.For more information on monitoring the Earth from Space with SeaWIFS see http://oceancolor.gsfc.nasa.gov/SeaWiFS/TEACHERS/. || ",

            "title": "Wind and Ocean Circulation shot for Dynamic Earth Dome Show",
            "description": "This visualization was created for the planetarium dome show film called Dynamic Earth. It is rendered with a fish-eye projection, called domemaster, which is why it looks circular. In a dome, the image fills the dome's hemisphere so that the parts near the bottom of the image are low and in front of the view, the top of the image is behind the viewer, and the left and right sides are to the left and right of the viewer.The camera slowly pushes in towards the Earth revealing global wind patterns. The wind patterns are from the MERRA computational model of the atomsphere. As the camera continues to push in, the winds fade away, revealing ocean currents which are driven, in part, by the winds. The ocean currents are from the ECCO-2 computational model of the oceans and ice. Only the higher speed ocean currents are shown. The camera moves around the Western Atlantic highlighting the Gulf stream from above and below. The camera finally emerges from beneath sea level and moves over to the Gulf of Mexico to examine the Loop Current.This shot is designed to seamlessly match to the end of the Earth/CME shot (animation id #3551.). Topographic features are exaggerated 20 times above water and 40 times below water. The exaggeration is primarily to allow the viewer to distinguish the depths of the flow fields.This visualization was shown in the \"VR Village\" at SIGGRAPH 2015. || ",

This was created for a planetarium dome show called Dynamic Earth and is produced in domemaster format (a type of fisheye projection).The domemaster format was created by rendering 7 separate camera tiles. The tiles were then stitched together to form final domemaster layers at 4096x4096 resolution and 16 bits per channel with premultiplied alpha and no gamma correction.

            "title": "Arctic and Antarctic Sea Ice for the Dynamic Earth Dome Show",
            "description": "Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover. This animation first shows the advance and retreat of the Arctic sea ice followed by same for the Antarctic sea ice. The sea ice changes from day to day showing a running 3-day average sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running miniimum of the AMSR-E 89 GHz brightness temperature. The animation ends by flying over the Antarctic Peninsula.This was created for a planetarium dome show called Dynamic Earth and is produced in 'domemaster format'. The domemaster format was created by rendering 7 separate 2048x2048 camera tiles. The tiles were then stitched together to form final domemaster at 4096x4096 resolution. Both the tiles and the domemaster were rendered with 16 bits per channel with no gamma correction. Two domemaster layers were generated for this animation: the Earth showing sea ice advancing or retreating rendered with transparency and the star background without transparency.This visualization was shown in the \"VR Village\" at SIGGRAPH 2015. || ",

Will the Earth be pummeled like its sister planet, Venus?Not this time, for the Earth has a fairly strong geomagnetic field.The geomagnetic field helps deflect the incoming blast of solar particles around the Earth, dramatically reducing the impact of the event.It is important to note that the flowing material of the CME are actually ions and electrons far too small to see.

Camera 00 is in the center of the domemaster, camera 01 is looking below camera 00, cameras 01 through 06 look around the outside of the dome master in counter-clockwise order.

            "description": "Energetic events on the Sun have impacts throughout the Solar System. This visualization, developed for the \"Dynamic Earth\" dome show, opens with a closeup view of the Sun. The solar imagery was collected from the Solar Dynamics Observatory (SDO) using an ultraviolet filter (wavelength 304 Ångstroms or 30.4 nanometers). We can observe jets of ionized gases, called prominences, erupting from the solar surface, and often constrained to loop-shaped trajectories due to the solar magnetic field.We pull out from the Sun to reveal the solar wind, which continuously streams outward from the Sun.We eventually reach the orbit of the planet Venus, the solar wind still streaming around us.But a massive eruption, called a coronal mass ejection, or CME, takes place on the Sun, sending a much higher density of particles (ions and electrons) outward into the solar wind.The wave of particles eventually strikes the planet Venus. But Venus has no significant magnetic field, and the particles make it directly to the atmosphere of the planet. These energetic solar events slowly blow away the atmosphere of the planet.The next part of this sequence is \"The Coronal Mass Ejection strikes the Earth!\".Technical DetailsThis is the dome show component moving from the Sun to Venus being hit by the CME.The domemaster format was created by rendering 7 separate camera tiles.

            "description": "A giant explosion of magnetic energy from the sun, called a coronal mass ejection, slams into and is deflected completely by the Earth's powerful magnetic field. The sun also continually sends out streams of light and radiation energy. Earth's atmosphere acts like a radiation shield, blocking quite a bit of this energy.Much of the radiation energy that makes it through is reflected back into space by clouds, ice and snow and the energy that remains helps to drive the Earth system, powering a remarkable planetary engine — the climate. It becomes the energy that feeds swirling wind and ocean currents as cold air and surface waters move toward the equator and warm air and water moves toward the poles — all in an attempt to equalize temperatures around the world.A jury appointed by the National Science Foundation (NSF) and Science magazine has selected \"Excerpt from Dynamic Earth\" as the winner of the 2013 NSF International Science and Engineering Visualization Challenge for the Video category. This animation will be highlighted in the February 2014 special section of Science and will be hosted on ScienceMag.org and NSF.govThis animation was selected for the Computer Animation Festival's Electronic Theater at the Association for Computer Machinery's Special Interest Group on Computer Graphics and Interactive Techniques (SIGGRAPH), a prestigious computer graphics and technical research forum. This is an excerpt from the fulldome, high-resolution show 'Dynamic Earth: Exploring Earth's Climate Engine.'

            "description": "Energetic events on the Sun have impacts throughout the Solar System. This visualization, developed for the Dynamic Earth dome show, utilizes data from space weather models based on a real coronal mass ejection (CME) event from mid-December 2003. Particles are used to represent the flow of solar material from the Sun around the Earth. It is important to note that the flowing material of the CME are actually ions and electrons far too small to see. This visualization tries to represent the motions of these tiny particles in a form large enough for us to see. We open with a close-up view of the Earth, the particles representing the solar wind streaming around the Earth due to extended influence of the Earth's magnetic field. We pull out from the Earth and move so that we see the Sun in the distance. The enormous density enhancement in the solar wind is the coronal mass ejection. As the CME reaches the Earth, we see how effective the Earth's magnetic field is at diverting the solar material around the Earth. As the CME passes, we move earthward, and reveal the field lines representing the Earth's magnetic field, emanating from the magnetic poles and blown behind the Earth due to the influence of the solar wind. For simplicity, we have represented the Earth's magnetic field as unchanging, but it is actually very dynamic in its response to a CME or other change in the solar wind. || ",
