            "title": "A Tour of the Cryosphere 2009",
            "description": "The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each year. Since ice and snow exist relatively close to their melting point, they frequently change from solid to liquid and back again due to fluctuations in surface temperature. Although direct measurements of the cryosphere can be difficult to obtain due to the remote locations of many of these areas, using satellite observations scientists monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.This animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The animation begins in Antarctica, showing some unique features of the Antarctic landscape found nowhere else on earth. Ice shelves, ice streams, glaciers, and the formation of massive icebergs can be seen clearly in the flyover of the Landsat Image Mosaic of Antarctica. A time series shows the movement of iceberg B15A, an iceberg 295 kilometers in length which broke off of the Ross Ice Shelf in 2000. Moving farther along the coastline, a time series of the Larsen ice shelf shows the collapse of over 3,200 square kilometers ice since January 2002. As we depart from the Antarctic, we see the seasonal change of sea ice and how it nearly doubles the apparent area of the continent during the winter.From Antarctica, the animation travels over South America showing glacier locations on this mostly tropical continent. We then move further north to observe daily changes in snow cover over the North American continent. The clouds show winter storms moving across the United States and Canada, leaving trails of snow cover behind. In a close-up view of the western US, we compare the difference in land cover between two years: 2003 when the region received a normal amount of snow and 2002 when little snow was accumulated. The difference in the surrounding vegetation due to the lack of spring melt water from the mountain snow pack is evident.As the animation moves from the western US to the Arctic region, the areas affected by permafrost are visible. As time marches forward from March to September, the daily snow and sea ice recede and reveal the vast areas of permafrost surrounding the Arctic Ocean.The animation shows a one-year cycle of Arctic sea ice followed by the mean September minimum sea ice for each year from 1979 through 2008. The superimposed graph of the area of Arctic sea ice at this minimum clearly shows the dramatic decrease in Artic sea ice over the last few years.While moving from the Arctic to Greenland, the animation shows the constant motion of the Arctic polar ice using daily measures of sea ice activity. Sea ice flows from the Arctic into Baffin Bay as the seasonal ice expands southward. As we draw close to the Greenland coast, the animation shows the recent changes in the Jakobshavn glacier. Although Jakobshavn receded only slightly from 1964 to 2001, the animation shows significant recession from 2001 through 2009. As the animation pulls out from Jakobshavn, the effect of the increased flow rate of Greenland costal glaciers is shown by the thinning ice shelf regions near the Greenland coast.This animation shows a wealth of data collected from satellite observations of the cryosphere and the impact that recent cryospheric changes are making on our planet.For more information on the data sets used in this visualization, visit NASA's EOS DAAC website.Note: This animation is an update of the animation 'A Short Tour of the Cryosphere', which is itself an abridged version of the animation 'A Tour of the Cryosphere'. The popularity of the earlier animations and their continuing relevance prompted us to update the datasets in parts of the animation and to remake it in high definition. In certain cases, our experiences in using the earlier work have led us to tweak the presentation of some of the material to make it clearer. Our thanks to Dr. Robert Bindschadler for suggesting and supporting this remake. || ",

            "description": "NASA's TRMM spacecraft is used by meteorologists to understand Hurricane Ivan.  TRMM snapped this view of Hurricane Ivan on September 15, 2004, just before the storm strikes land. The cloud cover is taken by TRMM's Visible and Infrared Scanner (VIRS).  The rain structure is taken by TRMM's Tropical Microwave Imager (TMI).  It looks underneath of the storm's clouds to reveal the underlying rain structure. Blue represents areas with at least 0.25 inches of rain per hour. Green shows at least 0.5 inches of rain per hour. Yellow is at least 1.0 inches of rain and red is at least 2.0 inches of rain per hour. || ",

            "description": "This animation follows Hurricane Isabel (2003) from its birthplace in the Ethiopian Highlands of East Africa, across the Atlantic Ocean, to the United States. Atlantic hurricanes are often formed as winds over the Gulf of Aden intersect with the Ethiopian Highlands. This animation zooms into the Ethiopian Highlands and shows several storms being formed. Then, the animation dissolves in a reticle to focus in specifically on the formation of Hurricane Isabel. The reticle follows the storm across Africa and into the Atlantic. The path and intensity of Hurricane Isabel is depicted by a colored path. Blue represents the genesis of the storm. Green is a Tropical Depression where winds are less than 39 miles per hour. Yellow is a Tropical Storm where winds are between 39 and 73 miles per hour. Red is a category 1 hurricane where winds are between 74 and 95 miles per hour. Light Red is a category 2 hurricane with winds between 96 and 110 miles per hour. Magenta is a category 3 hurricane with winds between 111 and 130 miles per hour. Light magenta is a category 4 hurricane with winds between 131 and 154 miles per hour. White represents a category 5 hurricane where winds are greater than 155 miles per hour. Note how Isabel gains size and speed over the warm waters of the Atlantic. || ",

            "title": "Satellite Imagery of Hurricane Dennis (WMS)",
            "description": "Hurricane Dennis started as a tropical depression on August 23, 1999, became a tropical storm on August 24, and was classified as a hurricane early on August 26, near the Bahamas.  From August 26 through August 31, Dennis proceeded up the coast of the United States until it stalled off the coast of North Carolina for four days because the pressure trough that was pushing it out to sea left it behind.  This animation shows images of Dennis during its hurricane period from August 26 through August 31, 1999, when the stall began.  The images were taken by the GOES-8 satellite, a weather satellite in geostationary orbit above the western hemisphere.  The continuous white cloud progression came from infrared images from GOES, and the yellowish clouds that come and go with the daylight came from data taken in the visible spectrum, also from GOES.  The GOES images were not taken at regular times, so the hurricane appears to slow down when the time between images gets small and speed up when the time between images gets large. || ",
