Dust Plumes Off North Africa
…
| Title |
Dust Plumes Off North Africa Coast |
| Description |
Streamers of dust flow out over the blue waters of the Mediterranean Sea from the northern shores of Africa's vast Sahara Desert. On November 14, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this image of rippling dust being swept northeastward across Libya (center) and Tunisia (top left). The winds that whipped up this dust may be part of a large weather system that brought severe storms—including gale force winds—to parts of Croatia, Italy, and Algeria. The dust plumes persisted for several days in mid-November. Image courtesy Jacques Descloitres, MODIS Rapid Response Team, NASA-Goddard Space Flight Center |

Dust Storm in Northern Africa |
| Description |
A dust storm several hundred kilometers across struck northern Africa on February 23, 2006. The storm carried Saharan dust across Algeria, Tunisia, and Libya, eventually sweeping over the Mediterranean Sea. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://aqua.nasa.gov/ ] satellite took this picture the same day. In this image, the dust storm appears as tendrils and ripples of pale beige, partially obscuring the underlying land and ocean features. The dust is not uniformly thick, so while part of the Mediterranean is almost completely hidden by a thick band of dust (in the upper right corner of the image), a burnt-orange-colored sliver of land still peeks out from under the dust in eastern Algeria and western Libya. Dust storms often originate from discrete source points, and this image shows several source points, one of which is annotated, in eastern Algeria. Additional dust appears to come from points farther west. As the world's largest sandy desert, the Sahara produces many of the planet's dust storms. Because the dust travels for hundreds to thousands of kilometers, its effects can be far reaching. According to a news report in The Jerusalem Post, dust storms now blow from Africa into Israel throughout the year, rather than just in the spring and summer, and climate change and desertification could exacerbate such storms in the coming decades. South of the dust storm, this picture shows part of the Tassili n'Ajjer National Park in southeastern Algeria. The park stands out from its surroundings due in part to its mountainous landscape. This high plateau in the middle of the Sahara sports some of the world's most important groupings of prehistoric cave art, recording climate change and animal migrations over the past several thousand years.

Dust still lingered over northern Africa on February 24, 2006, a day after a massive dust storm swept over Algeria, Tunisia, and Libya. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on February 24. In this image, a cloud of dust several hundred kilometers across extends from Libya and Egypt over the Mediterranean Sea. Faint tendrils of dust reach as far to the east as Israel. Although the dust hides many land features in northern Africa, the lush, green Nile Delta still stands out from its surroundings.

Dust Storm off Algeria
| Title |
Dust Storm off Algeria |
| Description |
On December 6, 2003, a wide plume of dust blew over North Africa and northwestward over the Mediterranean Sea. Tracking dust storms is important for a variety of reasons. Dust injects nutrients, such as iron, into marine ecosystems. Dust also carries bacteria and spores from fungi, which can cause disease far away. Dust storms can cause or worsen breathing problems. Finally, dust in the atmosphere can also influence climate and weather. Numerous dust storms carry Saharan dust across the Atlantic Ocean all the way to the Southeast United States and parts of Central and South America. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional spatial resolutions, including MODIS' maximum resolution of 250 meters.

Dust Storm Off the Coast of Algeria |
| Description |
The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ], flying onboard the Aqua [ http://www.aqua.nasa.gov/ ] satellite, captured this image on May 31, 2005, of an Algerian dust storm. The storm swept northward over the Mediterranean Sea toward the coast of Spain. A journey across the Mediterranean is a short trip for African dust, which often travels across the Atlantic to the Caribbean. Algeria provides the Mediterranean with a steady supply of dust and sand. More than 80 percent of Algeria is desert, including the enormous Issaouane Erg [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=16813 ] (sand sea) in the eastern part of the country. Large basins that may have held shallow seas or lakes, sand seas now hold active and fossilized sand dunes.

Dust Storm over Libya and Egypt |
| Description |
A thin sheet of dust blew northeastward from deserts in northern Africa and out across the Mediterranean Sea (upper right) on March 1, 2005. The orange-colored sands of eastern Algeria are thickly veiled with light-colored dust, which thins as it spreads more widely over Tunisia and Libya. The dust weaves both under and over clouds in different places over the Mediterranean. At the far right edge, the clouds appear bright white, and appear to be casting a shadow on the dust plume below them. At top center, dust appears to be above the clouds, giving them a dirty appearance. This image was made from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua [ http://aqua.nasa.gov ] satellite.

Fires in Algeria |
| Description |
Fires burning in the Atlas Mountains on the northern coast of Algeria turned deadly in late August 2007. Several people were killed by forest fires that were driven rapidly across the landscape by sirocco winds (hot dry winds that blow from Africa's interior deserts toward the Mediterranean). According to news reports, thousands of soldiers were deployed to help battle the fires. Cooler weather and firefighting efforts brought many fires under control by August 31. This image shows fires (red outlines) detected around the city of Skikda by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on August 30, 2007. Smoke creates a thick haze over the Mediterranean Sea. The large image provided above has a spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response Team provides twice-daily images of the western [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?AERONET_Blida ] and eastern [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?AERONET_Lampedusa ] Algerian coastline in additional resolutions.

Fires in Algeria |
| Description |
Scores of forest fires were burning in northern Algeria in late August 2007. Although much of the country is occupied by the Sahara Desert, Mediterranean forests, [ http://www.worldwildlife.org/wildworld/profiles/terrestrial/pa/pa1213_full.html ] woodlands, and chaparral occur on the Atlas Mountains that line the coast. On August 29, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite captured this image of the fires billowing thick clouds of brownish-gray smoke over the Mediterranean Sea. The smoke is so thick that the capital, Algiers, is not visible beneath it. According to news reports, dozens of families have had to evacuate, and the number of people seeking medical attention for respiratory and allergy problems has dramatically increased. The large image provided above has a spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response Team provides twice-daily [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?AERONET_Blida ] images of the region in additional resolutions.

Saharan Dust over Italy |
| Description |
*Saharan Dust over Italy* A thick plume of Saharan Desert dust blew toward the northeast over Algeria and Tunisia and across the Mediterranean Sea on February 22, 2004. The dust was so thick it almost completely obscured the view of the surface in this true-color image acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite. The path of the dust storm carried it directly over the island of Sicily and Italy's southern mainland. The tan color of the dust makes it easy to distinguish from the much brighter, white clouds in the scene. The high-resolution copy of the image above is 500 meters per pixel. This scene is also available at additional resolutions. Image courtesy Jacques Descloitres, MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC |

Smoke from Fires in Greece
| Title |
Smoke from Fires in Greece |
| Description |
Besides laying waste to huge areas of forest, fires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14474 ] burning in Greece in August 2007 released pollutants that traveled across the Mediterranean Sea and into Africa. This image shows aerosols—tiny solid or liquid particles suspended in air—observed by the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite layered on the photo-like Blue Marble [ http://earthobservatory.nasa.gov/Newsroom/BlueMarble/ ] composite image. Relatively clear air is transparent. Highest aerosol concentrations are pink. On August 26, 2007, aerosols from the fires on the southwestern coast of Greece took a fairly direct route across the Mediterranean Sea to the western part of the Libyan coast. A large pool of smoke collected over the Gulf of Sirte, off the Libyan coast. Another pocket of thick aerosols appears over Algeria. These particles are probably smoke emitted from fires burning in Algeria [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14478 ] over a long stretch of the coastal Atlas Mountains. Farther south over the deserts of northern Africa, the light green areas of moderate aerosol amounts could be smoke or dust. On August 27, 2007, aerosols still crossed the Mediterranean Sea, but they took a more circular route. They spread southward in a clockwise direction from Greece, across the island of Crete, and concentrated thickly over eastern Libya. The other large pocket of aerosols—the pink patch hovering over the border of Libya and Algeria—may include smoke from Algeria and Greece. As on the previous day, some aerosols collected over Egypt and eastern Libya. OMI detects the amount of light of different wavelengths that the atmosphere scatters back to space, the amount of backscattered sunlight is affected by what is in the atmosphere. To make an aerosol index with OMI data, scientists compare the amount of ultraviolet (UV) light the atmosphere scatters back at given place and time to the amount of UV light that the atmosphere would scatter back if it were totally clear. You can download a KMZ file KMZ file of the smoke from Greece suitable for use with Google Earth [ http://earth.google.com/ ] for both August 26 [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Aug2007/greece_omi_2007238.kmz ] and August 27.
