Description El Sheik, Egypt--The Red Sea golf resort in Sharm El Sheik, Egypt, where President Clinton met with Israeli Prime Minister Ehud Barak and Palestinian Authority President Yasser Arafat, stands out against the desert landscape in this image acquired on August 25, 2000. This image of the southern tip of the Sinai Peninsula shows an area about 30 by 40 kilometers (19 by 25 miles) in the visible and near infrared wavelength region. Vegetation appears in red. The blue areas in the water at the top and bottom of the image are coral reefs. The airport is visible just to the north of the golf resort. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader, Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high- resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface. The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands Evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface heat balance. JPL is a division of the California Institute of Technology, Pasadena, Calif. #####

Title Dust over the Red Sea
Description A dust storm blew across the Red Sea on June 9, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture the same day. In this image, a dust plume partially obscures the view of the Red Sea, between Egypt in the west, and Saudi Arabia in the east. Extreme summer heat increases the likelihood of dust storms, and the sand seas of the Middle East produce many of the planet's dust plumes.

Title Dust Plume off the Coast of Sudan
Description On June 23, 2007, a dust storm began blowing off the coast of Sudan over the Red Sea. Dust continued blowing off the coast for the next several days. On June 28, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image. This image shows two principal plumes blowing off the coast of Sudan, with numerous smaller plumes in between them. The plumes blow mostly toward the northeast, creating tan-colored blurs over the ocean surface below. Not all of the Red Sea's pale color, however, is due to dust. Some of its light appearance results from sunglint caused by the Sun's light reflecting off the ocean surface and directly back into the satellite sensor.

Dust Storm over the Red Sea
Title Dust Storm over the Red Sea
Description An enormous cloud of dust blanketed the Red Sea on July 26, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image. It is hard to tell just where the dust is coming from here, the Red Sea is sandwiched between several deserts that are capable of producing spectacular dust storms. On the west side of the sea, the Nubian Desert of Sudan (center left) appears slightly blurred through a light haze of dust, hinting that the dust may have come from the west as such storms often do. On the top of the image, however, the dust appears to be blowing out of the east. Desert flanks the Red Sea on the east in the form of the Tihamat ash Sham, the pale strip of land barely visible along the eastern shore of the sea. The dust is thicker here, pooling in a distinct line at the foot of the Jabal al Hijaz (Hijaz Mountains). Beyond the mountains are the great sand deserts of Saudi Arabia. To the north of the dust storm, the air over the Red Sea is clear. Coral reefs around the islands create flashes of brilliant turquoise in the clear black of the sea.

Dust Storm over the Red Sea
Title Dust Storm over the Red Sea
Description In the summer months in the Northern Hemisphere, dust storms originating in the deserts around the Arabian Peninsula have a significant impact on the amount of solar radiation that reaches the surface. Winds sweep desert sands into the air and transport them eastward toward India and Asia with the seasonal monsoon. These airborne particles absorb and deflect incoming radiation and can produce a cooling effect as far away as North America. According to calculations performed by the NASA Goddard Institute for Space Studies (GISS), the terrain surrounding the southern portions of the Red Sea is one of the areas most dramatically cooled by the presence of summertime dust storms. That region is shown experiencing a dust storm in this true-color image from the Moderate Resolution Imaging Spectroradiometer (MODIS) acquired on July 11, 2002. The GISS model simulations indicate that between June and August, the temperatures would be as much as 2 degrees Celsius warmer than they are if it weren't for the dust in the air?a cooling equivalent to the passage of a rain cloud overhead. The image shows the African countries of Sudan (top left), Ethiopia (bottom left), with Eritrea nestled between them along the western coast of the Red Sea. Toward the right side of the image are Saudi Arabia (top) and Yemen (bottom) on the Arabian Peninsula. Overlooking the Red Sea, a long escarpment runs along the western edge of the Arabian Peninsula, and in this image appears to be blocking the full eastward expansion of the dust storm.

Jebel at Tair Eruption
Title Jebel at Tair Eruption
Description Jebel at Tair, a volcanic island in the Red Sea, erupted at the end of September 2007. The eruption released lava and ash, and created a spectacular light show, according to observers in the area. On October 15, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite acquired this image. This shows a largely quieted volcano releasing only a faint volcanic plume. ASTER measures light visible to human eyes and infrared light, enabling the sensor to detect thermal anomalies caused by substantial temperature differences. The bright red spot at the summit is a thermal anomaly. A smaller, fainter anomaly appears just northwest of the summit. The volcano's slopes bear the marks of previous eruptions, the darker streaks indicating more recent lava flows.Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano—a cone composed of alternating layers of ash, lava, and rocks from earlier eruptions. The latest eruption is a continuation of activity on this island, where explosive eruptions were recorded in the eighteenth and nineteenth centuries. The volcano is known by multiple names and spellings, including Jabal al-Tair, Jabal al-Tayr, Tair Island, Al-Tair Island, Djebel Teyr, and Jibbel Tir. You can download a 15-meter-resolution KMZ file of Jebel al-Tair [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Oct2007/jebelaltair_ast_2007288.kmz ] suitable for use with Google Earth.

Texas-sized Dust Storm Sweep …
Title Texas-sized Dust Storm Sweeps over Egypt
Description The massive Saharan dust storm, originating on Jan. 22, continued spreading north and eastward across Egypt on Jan. 23, 2004. In this true-color scene, the dust (tan pixels) can be seen blowing over the Sinai Peninsula and blanketing parts of Israel, Syria, western Iraq, and almost all of Jordan. To the south, the Red Sea is almost completely obscured as the dust also crosses over into Saudi Arabia. The bright white patches are clouds. This image was acquired by the Moderate Resolution Imaging Spectroradiomater (MODIS), flying aboard NASA's Terra satellite. Notice the vertical discontinuity running vertically down through the image just right of center. This shows where two images from consecutive satellite overpasses were stitched together to make one image. The high-resolution version available above is 500 meters per pixel, but the scene is also available at MODIS' fullest resolution of 250 meters.

ASTER
Title ASTER Suez Canal
Original Caption Released with Image One of the most important waterways in the world, the Suez Canal runs north to south across the Isthmus of Suez in northeastern Egypt. This image of the canal covers an area 36 kilometers (22 miles) wide and 60 kilometers (47 miles) long in three bands of the reflected visible and infrared wavelength region. It shows the northern part of the canal, with the Mediterranean Sea just visible in the upper right corner. The Suez Canal connects the Mediterranean Sea with the Gulf of Suez, an arm of the Red Sea. The artificial canal provides an important shortcut for ships operating between both European and American ports and ports located in southern Asia, eastern Africa, and Oceania. With a length of about 195 kilometers (121 miles) and a minimum channel width of 60 meters (197 feet), the Suez Canal is able to accommodate ships as large as 150,000 tons fully loaded. Because no locks interrupt traffic on this sea level waterway, the transit time only averages about 15 hours. ASTER acquired this scene on May 19, 2000. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite.

Title The Nile
Original Caption Released with Image This image of the northern portion of the Nile River was captured by MISR's nadir camera on January 30, 2001 (Terra orbit 5956). The Nile is the longest river in the world, extending for about 6700 kilometers from its headwaters in the highlands of eastern Africa. At the apex of the fertile Nile River Delta is the Egyptian capital city of Cairo. To the west are the Great Pyramids of Giza. North of here the Nile branches into two distributaries, the Rosetta to the west and the Damietta to the east. Also visible in this image is the Suez Canal, a shipping waterway connecting Port Said on the Mediterranean Sea with the Gulf of Suez. The Gulf is an arm of the Red Sea, and is located on the righthand side of the picture. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

Title The Size of Dust and Smoke
Original Caption Released with Image Desert dust particles tend to be larger in size than aerosols that originate from the processes of combustion. How precisely do the size of the aerosol particles comprising the dust that obscured the Red Sea on July 26, 2005, contrast with the size of the haze particles that obscured the United States eastern seaboard on the same day? NASA's Multi-angle Imaging SpectroRadiometer (MISR), which views Earth at nine different angles in four wavelengths, provides information about the amount, size, and shape of airborne particles. Here, MISR aerosol amount and size is presented for these two events. These MISR results distinguish desert dust, the most common non-spherical aerosol type, from pollution and forest fire particles. Determining aerosol characteristics is a key to understanding how aerosol particles influence the size, abundance, and rate of production of cloud droplets, and to a better understanding of how aerosols influence clouds and climate. The left panel of each of these two image sets (Red Sea, left, U.S. coastline, right) is a natural-color view from MISR's 70-degree forward viewing camera. The color-coded maps in the central panels show aerosol optical depth, the right panels provide a measure of aerosol size, expressed as the "Angstrom exponent." For the optical depth maps, yellow pixels indicate the most optically-thick aerosols, whereas the red, green and blue pixels represent progressively decreasing aerosol amounts. For this dramatic dust storm over the Red Sea, the aerosol is quite thick, and in some places, the dust over water is too optically thick for MISR to retrieve the aerosol amount. For the eastern seaboard haze, the thickest aerosols have accumulated over the Atlantic Ocean off the coasts of South Carolina and Georgia. Cases where no successful retrieval occurred, either due to extremely high aerosol optical thickness or to clouds, appear as dark gray pixels. For the Angstrom exponent maps, the blue and green pixels (smaller values) correspond with more large particles, whilst the yellow and red pixels, representing higher Angstrom exponents, correspond with more small particles. Angstrom exponent is related to the way the aerosol optical depth (AOD) changes with wavelength -- a more steeply decreasing AOD with wavelength indicates smaller particles. The greater the magnitude of the Angstrom exponent, the greater the contribution of smaller particles to the overall particle distribution. For optically thick desert dust storms, as in this case, the Angstrom exponent is expected to be relatively low -- likely below 1. For the eastern seaboard haze, the Angstrom exponent is significantly higher, indicating the relative abundance of small pollution particles, especially over the Atlantic where the aerosol optical depth is also very high. With a nearly simultaneous data acquisition time, the MODIS instrument also collected data for these events, and image features for both the dust storm and the haze are available., The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously, viewing the entire globe between 82° north and 82° south latitude every nine days. This image covers an area of about 1,265 kilometers by 400 kilometers. These data products were generated from a portion of the imagery acquired during Terra orbits 29809 and 29814 and utilize data from blocks 60 to 67 and 71 to 78 within World Reference System-2 paths 17 and 170, respectively. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Science Mission Directorate, Washington, DC.

Title MISR Views the Middle East
Original Caption Released with Image This image, generated using 16 orbits of MISR data collected between August 16 and August 30, 2000, takes us to the cradle of many civilizations. The data are from the 60-degree aftward-viewing camera. Because the individual orbit swaths are only 400 kilometers wide, they were "mosaiced" together to form this composite picture, which covers about 2700 kilometers from west to east and 1750 kilometers from north to south. A few discontinuities are present in the mosaic, particularly near clouds, due to changes in the scene which occurred between dates when the individual orbit data were acquired. At the northern tip of the Red Sea, the Gulf of Suez and the Gulf of Aqaba frame the sandy deserts and spectacular mountains of the Sinai Peninsula. The highest peaks are Gebel Katherina (Mountain of St. Catherine, 2637 meters) and Gebel Musa (Mountain of Moses, also known as Mount Sinai, 2285 meters). To the northeast, Israel and Jordan flank the Dead Sea, one of the saltiest inland water bodies in the world. At its northern edge is Qumran, where the ancient Scrolls were discovered, the city of Jerusalem lies about 30 kilometers to the west. Several large rivers are prominent. Flowing southeastward through Iraq are the Tigris and Euphrates. The dark area between the two rivers, northwest of the Persian Gulf, is a very fertile region where fishing and farming are prevalent. Wending its way through eastern Egypt is the Nile. In the south is Lake Nasser and the Aswan Dam, continuing northward the Nile passes the Temple of Luxor as it sharply loops to the east. It then turns west and northward, eventually passing the capital city of Cairo, and finally spreading into a prominent delta as it empties into the Mediterranean Sea. The bright dot just west of the apex of the delta marks the location of the great Pyramids and Sphinx complexes on the Giza Plateau. On the coast, west of the delta, is the ancient city of Alexandria, Egypt's main seaport."MISR", as it turns out, is the transliteration of the Arabic name for Egypt.
