Title Sample LIMA Data versus MOA Data of Ross Island
Abstract The Landsat Image Mosaic of Antarctica (LIMA) is a data product funded by the National Science Foundation (NSF) and jointly produced by the U.S. Geological Survey (USGS), the British Antarctic Survey (BAS), and the National Aeronautics and Space Administration (NASA). The images shown here are compared to what is currently the best mosaic of Antarctica called the MODIS Mosaic of Antarctica (MOA). MOA is a composite of 260 swaths comprised of both Terra and Aqua MODIS images acquired between November 20, 2003 and February 29, 2004. MOA's data resolution is approxiately 150 meters per pixel. From large continental views of Antarctica, MOA is more than adequate. However, as we get closer in to the surface, the resolution of the MOA data begins to show, thus highlighting the value of the LIMA product once it is complete. The LIMA data shown here uses the pan-chromatic band which translates to a resolution of 15 meters per pixel (opposed to MOA's 150 meters per pixel resolution). The 13 swaths used to generate this sample mosaic where acquired between December 25, 1999 and December 31, 2001. The elevation shown is actual (1x). Comparing this sample LIMA dataset alongside MOA data over the same region shows the value of having a higher resolution view of Antarctica.

Title Global View of the Arctic and Antarctic on September 21, 2005
Abstract In support of International Polar Year, this matching pair of images showing a global view of the Arctic and Antarctic were generated in poster-size resolution. Both images show the sea ice on September 21, 2005, the date at which the sea ice was at its minimum extent in the northern hemisphere. The color of the sea ice is derived from the AMSR-E 89 GHz brightness temperature while the extent of the sea ice was determined by the AMSR-E sea ice concentration. Over the continents, the terrain shows the average landcover for September, 2004. (See Blue Marble Next Generation) The global cloud cover shown was obtained from the original Blue Marble cloud data distributed in 2002. (See Blue Marble:Clouds) A matching star background is provided for each view. All images include transparency, allowing them to be composited on a background.

Hurricane Dennis
Title Hurricane Dennis
Abstract The formation of Hurricane Dennis on July 5 made that the earliest date on record that four named storms formed in the Atlantic basin. Dennis proved to be a powerful and destructive storm in the Caribbean Sea and the Gulf of Mexico. It crossed over Cuba on July 8 and 9, leaving at least 10 dead, and caused additional deaths in Haiti. After re-emerging over open water, Dennis re-strengthened into a dangerous Category 4 hurricane with top wind speeds of 233 kilometers per hour (145 mph). The storm passed within 90 kilometers (55 miles) of Pensacola, Florida, and hit land about 80 kilometers (50 miles) east of where Hurricane Ivan struck in September, 2004. A large storm surge of more than 10 feet was created in certain areas, and many homes and businesses in low-lying areas were flooded.

Title Average Clear-sky Outgoing Longwave Flux (WMS)
Abstract The Earth's climate is determined by energy transfer from the sun to the Earth's land, oceans, and atmosphere. As the Earth rotates, the sun lights up only part of the Earth at a time, and some of that incoming solar energy is reflected and some is absorbed, depending on type of area it lights. The average amount of reflection and absorption is critical to the climate, because the absorbed energy heats up the Earth until it is radiated away as thermal radiation. This animation shows the monthly average clear-sky outgoing longwave radiation from July, 2002 through June, 2004 as measured by the CERES instrument. This is the thermal radiation given off by the warm Earth when the sky is cloud free. The Earth's rotation and the movement of warm air from the equator to the poles make the Earth roughly uniformin temperature. The most visible features are the cold poles in winter and the significant regions of snow coverage in the northern hemisphere, also in winter.

The average amount of reflection and absorption is critical to the climate, because the absorbed energy heats up the Earth until it is radiated away as thermal radiation. This animation shows the monthly average clear-sky albedo from July, 2002 through June, 2004 as measured by the CERES instrument. This is the fraction of the incoming solar radiation that is reflected back into space by regions of the Earth on cloud-free days. The regions of highest albedo are regions of snow and ice, followed by desert regions. Oceans have the lowest albedo, and reflect very little of the incoming solar radiation. It is not possible to measure the albedo during the winter months at the poles, since there is no incoming solar radiation during these times.

Title Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006
Abstract Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. As more ice moves from glaciers on land into the ocean, ocean sea levels raise. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This animation shows the glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006. This animation is an update of and extension to animation ID #3374. In this version, a pause is added on the approach to the Jakobshavn glacier in order to highlight the meltwater lakes visible on the Greenland ice sheet. In addition, semi-transparent overlays and text indicate different regions of the glacier before the calving lines are shown. After the calving front retreat, an additional segment shows a zoom to a global view. During the pull out, historic calving front locations are shown followed by a color overlay showing regions of increase and decrease in the Greenland ice sheet.

The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This animation shows the glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006. This animation is an update of and extension to animation ID #3374. In this version, a pause is added on the approach to the Jakobshavn glacier in order to highlight the meltwater lakes visible on the Greenland ice sheet. In addition, semi-transparent overlays and text indicate different regions of the glacier before the calving lines are shown. After the calving front retreat, an additional segment shows a zoom to a global view. During the pull out, historic calving front locations are shown followed by a color overlay showing regions of increase and decrease in the Greenland ice sheet.

Title Average Total-sky Incoming Solar Flux (WMS)
Abstract The Earth's climate is determined by energy transfer from the sun to the Earth's land, oceans, and atmosphere. As the Earth rotates, the sun lights up only part of the Earth at a time, and some of that incoming solar energy is reflected and some is absorbed, depending on type of area it lights. The average amount of reflection and absorption is critical to the climate, because the absorbed energy heats up the Earth until it is radiated away as thermal radiation. This animation shows the monthly average incoming solar radiation from July, 2002 through June, 2004 as measured by the CERES instrument. This average data set is contant in longitude because of the Earth's rotation, but clearly shows the seasonal cycle as the sun heats the Northern Hemisphere more in summer than in winter. Note that the polar regions are abnormally bright in the local summer and dark in the local winter because whole day is either light or dark in those seasons.
