            "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. A composite version is provided along with the layers. There are 3 domemaster layers intended to be composited as follows: the Earth and orbits layer over Sun layer over star field (no alpha channel). || ",

            "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. || ",

            "description": "Earth and the planets sit in the crosshairs of multiple streams of solar power. Giant explosions on the sun, called coronal mass ejections, blast electrically charged particles across the solar system, where they are deflected by Earth's strong magnetic field. As the sun endlessly emits solar radiation, a different kind of protective layer—Earth's gaseous atmosphere—shields the planet from harmful rays. But it is the radiation that penetrates the atmosphere and is absorbed by Earth's surface that makes life possible and drives a remarkable planetary engine—the climate. This narrated animation uses NASA satellite and model data to illustrate the fundamental power of the sun and how its energy drives the winds and ocean currents on Earth. It is an excerpt from \"Dynamic Earth: Exploring Earth's Climate Engine,\" a fulldome, high-resolution movie now playing at planetariums around the world. || ",

            "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.' The Dynamic Earth dome show was selected as a finalist in the Jackson Hole Wildlife Film Festival Science Media Awards under the category \"Best Immersive Cinema - Fulldome\". || ",
