Calm before the Dust Storm
| Title |
Calm before the Dust Storm |
| Description |
On February 3, 2004, a large dust storm swept westward off the coast of northwest Africa and, for the last two days has been fanning out to the north and west over a large portion of the eastern Atlantic Ocean. This true-color image was acquired on February 6 by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Terra satellite. The scene shows the West African coastline from Morocco (upper right) to Guinea Bissau (lower right). Streamers of Saharan Desert dust (tan pixels) continue to blow out from Morocco toward the Canary Islands, while the Cape Verde Islands to the south (bottom center) appear to have taken the full brunt of the dust storm. As it moved westward, the dust appears to have become entrained into a strong southerly air current, creating a vast arc of dust stretching more than 2,000 km. Notice the ?wind shadow? extending northwestward from the Cape Verde Islands. The islands formed a break against the wind, creating a clear pocket of air behind them that is itself being pulled and carried northward with the strong southerly wind. This image is also available in additional resolutions. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov/ ] at NASA GSFC |

Forest Fires in Portugal |
| Description |
Portugal?s severe fire season isn?t over yet, with new blazes breaking out across the country at the end of the second week of September. With temperatures near 100 degrees F for several days, firefighters face a difficult challenge, particularly in the southern coastal region of Algarve, a popular tourist destination. In this Moderate Resolution Imaging Spectroradiometer (MODIS) image from September 12, 2003, a large fire was detected and is marked with red at the southwest tip of the country. A long smoke plume trails over the Atlantic from the blaze. Meanwhile, a dust storm is bringing a cloud of dust and sand northward over Morocco and the Atlantic Ocean. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS? maximum spatial resolution of 250 meters.

Dust Storm off Morocco |
| Description |
Bright yellow streamers of dust sweep off North Africa?s Moroccan coast toward the Canary Islands in this true-color Terra MODIS image from February 17, 2004. Beneath the dust, the G?Aydat al Jhoucha mountains are darker shades of brown marching toward the coast. Just off the coast of Lanzarote Island, the northeastern-most of the Canaries, gravity waves caused by the high winds driving the dust storm create dark and light stripes on the water. More gravity waves stretch from Gran Canaria, the round island toward the center of the group, toward the Moroccan coast. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Dust Storm over the Canary I
…
| Title |
Dust Storm over the Canary Islands |
| Description |
Saharan dust blew off the west coast of Africa and over the Canary Islands on November 11, 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, parallel plumes of pale beige dust blow off the coasts of Morocco and Western Sahara. The "lines" of dust are more distinct off the coast of Morocco than off the coast of Western Sahara, where the dust plumes are more amorphous. The dust from Morocco may originate from more discrete source points, separated by areas with little or no loose dust that can easily be lifted by wind. Regardless of their shape, all the plumes blow toward the northwest, and although the islands of Tenerife and Gran Canaria appear unaffected, the neighboring islands of Fuerteventura and Lanzarote are receiving a strong dose of dust. Fringing the edges of this image are fluffy white clouds. It is possible that the same weather system associated with the cloud cover in this image has produced the winds that move the dust. The Sahara Desert produces a steady supply of dust, and the Canary Islands prove frequent targets. Saharan dust often travels much farther than these islands, it often crosses the Atlantic and reaches islands in the Caribbean where it proves to be a mixed blessing. While heavy doses of dust can damage coral reefs, the same dust supplies soil to islands that would otherwise be barren rock. A 250-meter-resolution KMZ file [ http://earthobservatory.nasa.gov/Newsroom/NewImages/Images/CanaryIslands.A2006315.1115.250m.kmz ] of the dust blowing over the Canary Islands is available for use with Google Earth.

ASTER
| Title |
ASTER Gibraltar |
| Original Caption Released with Image |
The Strait of Gibraltar separates Spain from Morocco. This image, acquired on July 5, 2000, covers an area 34 kilometers (21 miles) wide and 59 kilometers (37 miles) long in three bands of the reflected visible and infrared wavelength region. The promontory on the eastern side of the conspicuous Spanish port is the Rock of Gibraltar. Once one of the two classical Pillars of Hercules, the Rock was crowned with silver columns by Phoenician mariners to mark the limits of safe navigation for the ancient Mediterranean peoples. The rocky promontory still commands the western entrance to the Mediterranean Sea. The rocky limestone and shale ridge rises abruptly from the sea, to a maximum elevation of 426 meters (1,398 feet). A British colony, Gibraltar occupies a narrow strip of land at the southernmost tip of the Iberian Peninsula. It is separated from the Spanish mainland by a neutral zone contained on a narrow, sandy isthmus. Because of its strategic location and formidable topography, Gibraltar serves mainly as a British fortress. Most of its sparse land is taken up by air and naval installations, and the civilian population is small. 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, California, 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. Examples of applications include monitoring glacial advances and retreats, potentially active volcanoes, thermal pollution, and coral reef degradation, identifying crop stress, determining cloud morphology and physical properties, evaluating wetlands, mapping surface temperature of soils and geology, and measuring surface heat balance. |

Where Europe meets Africa |
| Original Caption Released with Image |
Data from a portion of the imagery acquired by the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera during 2000-2002 were combined to create this cloud-free natural-color mosaic of southwestern Europe and northwestern Morocco and Algeria. The image extends from 48°N, 16°W in the northwest to 32°N, 8°E in the southeast. It is displayed in Albers conic equal-area projection (a projection which is frequently used for equal-area maps of regions that are predominantly east-west in extent). From the northeast, the image traverses a portion of the Swiss Alps (partially snow-covered) and a small part of Italy's Po Valley. The northern portion of the image also includes the western coast of France and much of southern and southwestern France's undulating terrain, which continues until reaching the hills of the Pyrenees. The Pyrenees act as the natural frontier to the Iberian Peninsula -- a landmass comprised of Spain and Portugal. The Peninsular landscapes are extremely varied, with some almost desert-like, others green and fertile. About half of Spain is situated atop a high plain, known as the Central Plateau, and many mountain ranges, rivers, geological basement rock and vegetation types are found across this great plateau. The largest alluvial plain is Andalusia in the south, where the valley of the Guadalquivir River is shut in by mountain ranges on every side except the southwest, where the valley descends to the Atlantic. The islands of Mallorca, Menorca and Ibiza are Spanish territories in the western Mediterranean. At the Strait of Gibralter, Spain and Morocco very nearly kiss, and Morocco appears relatively verdant along its northern coastal corner. The rugged Atlas Mountain ranges traverse northern Algeria and Morocco. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously from pole to pole, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during 2000-2002. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. |

| Title |
Anti-Atlas Mountains, Morocco |
| Original Caption Released with Image |
The Anti-Atlas Mountains of Morocco formed as a result of the collision of the African and Eurasian tectonic plates about 80 million years ago. This collision destroyed the Tethys Ocean, the limestone, sandstone, claystone, and gypsum layers that formed the ocean bed were folded and crumpled to create the Atlas and Anti-Atlas Mountains. In this ASTER image, short wavelength infrared bands are combined to dramatically highlight the different rock types, and illustrate the complex folding. The yellowish, orange and green areas are limestones, sandstones and gypsum, the dark blue and green areas are underlying granitic rocks. The ability to map geology using ASTER data is enhanced by the multiple short wavelength infrared bands, that are sensitive to differences in rock mineralogy. This image was acquired on June 13, 2001 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. 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 Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring of 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. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader, Bjorn Eng of JPL is the project manager. The Terra mission is part of NASA's Earth Science Enterprise, a long- term research effort to understand and protect our home planet. Through the study of Earth, NASA will help to provide sound science to policy and economic decision-makers so as to better life here, while developing the technologies needed to explore the universe and search for life beyond our home planet.
