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.

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.

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.

Locusts Plague Northwest and
| Title |
Locusts Plague Northwest and Western Africa |
| Description |
A wet winter and spring settled over northwestern Africa in 2004, and the dry Sahel bloomed with life. As the desert turned green, the plentiful water nourished more than vegetation. Buried in the sandy soils were the eggs of desert locusts, waiting to absorb moisture and hatch. This year, there was enough water and vegetation to support large populations of young locusts, and by late summer, several large swarms had developed. Swarms of locusts can contain as many as 80 million locusts per square kilometer, and may cover several square kilometers. An adult locust can eat its own weight in food every day, about two grams, which means that, according to the Food and Agriculture Organization (FAO) of the United Nations, a small part of a typical swarm can eat as much food as 2,500 people in a single day. At these rates, the locusts consume most vegetation in their path and then must migrate to find new sources of food. The locust outbreak of 2004 began in Morocco and Algeria in northwestern Africa. While the locusts can't be seen in satellite imagery, the conditions that support them are clearly visible. The above image shows how vegetation differed from previous years. The image is a composite of Normalized Difference Vegetation Index (NDVI) data collected between April 6 and April 13, 2004. Green areas indicate that there was more vegetation in the region than the average of the past four years. Not surprisingly, these areas correlate well with the early breeding grounds of the locusts near the interface between dry desert land and wetter coastal land. When their numbers and the ending growing season forced the locusts to move, they traveled south and east on the summer winds. As of October 5, the locusts had expanded to the south in a band that stretched from Mauritania to Chad?a distance of roughly 4,000 kilometers. Currently, Mauritania is the worst affected, but Senegal, Mali, Burkina Faso, Niger, Chad, and the Cape Verde Islands have also been plagued with locusts. The swarms are now starting to move north again, this time into Libya and Algeria. On October 1, three to four million hectares of land were infested with locusts. As before, satellite imagery shows where locust swarms can migrate to find food by indicating where food is available. In the lower image, a composite of data collected between August 28 and September 4, 2004, pockets of green in southern Mauritania, Senegal, Mali, and Burkina Faso show where the locusts are finding food and breeding. The most recent information from FAO shows that these are indeed the areas where the locusts are concentrated. Though the locusts themselves are harmless, they can cause significant crop damage. The worst of the problem is in Mauritania, where dark clouds of locusts have swarmed over much of the country. Rainfall had been good, and farmers anticipated a better-than-average harvest until the locusts arrived. Mauritania?s national food security authority expected to lose up to 75, percent of the cereal crop, though the Food and Agriculture Oragnization (FOA) of the United Nations expected a smaller loss. Undoubtedly, the insects are causing considerable damage, but both the Foreign Agricultural Service [ http://www.fas.usda.gov/pecad/highlights/2004/08/west_africa/index.htm ] of the United States Department of Agriculture and the FAO say that it?s too early to quantify how the outbreak will impact overall production. Harvest began in September and continues through November, and the amount of crops that the locusts consume in the meantime will depend on how effective efforts to control them are and whether or not the locusts continue to breed.

Fires in the Canary Islands |
| Description |
Two large forest fires raged on the Canary Islands on the afternoon of July 30, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this photo-like image. Clusters of red dots mark out the locations of the fires on the islands of Tenerife (left) and Gran Canaria (right). More than 2,000 people were evacuated from the fire on Gran Canaria, which had burned through 8,645 acres of woodland, reported the Associated Press on July 30. Thick plumes of smoke blow southwest over the Atlantic Ocean from the fires. The desert coast of Western Sahara and Morocco makes up the right edge of the image. A faint tan veil of dust hangs over the ocean near the coast. The large image provided above has a resolution of 250 meters per pixel.

Flooding in Morocco
| Title |
Flooding in Morocco |
| Description |
Unusually heavy rains hit Morocco in late November 2002, giving rise to floods that killed more than 60 people. The above false-color image (right) displays some of the worst of the flooding just north of the city of Rabat, located on Morocco?s coast. The image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, flying aboard NASA?s Aqua spacecraft. Most of the casualties were due to flash flooding throughout the western half of Morocco. The water from the flash floods has drained into the now swollen riverbeds and lakebeds that appear as solid blue in the image. The floodwaters washed away loose sediment from the surrounding countryside and carried it to the Atlantic Ocean to form the sediment plumes that appear along the coast. Normally, hardly any standing water in Morocco is visible in MODIS imagery (left, acquired November 7, 2002). In these false color images land is green and tan, clouds are white and light blue, and water is dark blue and black. Image courtesy Jeff Schmaltz, MODIS Rapid Response Team, NASA GSFC |

Which image is Earth, and which is Mars? One of the above image [ http://photojournal.jpl.nasa.gov/catalog/PIA05102 ]s was taken by the robot Spirit rover [ http://marsrovers.jpl.nasa.gov/overview/ ] currently climbing Husband Hill [ http://dsc.discovery.com/news/briefs/20050207/mars.html ] on Mars [ http://www.nineplanets.org/mars.html ]. The other image was taken by a human across the desert south of Morocco [ http://www.cia.gov/cia/publications/factbook/geos/mo.html ] on Earth [ http://earthobservatory.nasa.gov/ ]. Both images show vast plains covered with rocks and sand [ http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search?spirit+mars ]. Neither shows water or obvious signs of life [ http://astrobiology.arc.nasa.gov/roadmap/goals/g8_mars_europa.html ]. Each planet [ http://antwrp.gsfc.nasa.gov/apod/mars.html ] has a surface so complex [ http://antwrp.gsfc.nasa.gov/apod/ap050306.html ] that any one image does not do that planet justice [ http://www.un.org/law/ ]. Understanding either one, it turns out, helps understand [ http://calspace.ucsd.edu/marsnow/library/science/comparative_planetology/ ] the other. Does the one on the left look like home? Possibly not, but it is Earth [ http://antwrp.gsfc.nasa.gov/apod/ap050102.html ]. |
