| Title |
Haze and Pollution over Western Europe |
| Description |
The United Kingdom was uncommonly cloud free on March 29, 2002, as can be seen in this SeaWiFS image. Much of mainland Western Europe also had clear skies, albeit somewhat hazy. At the southern extreme of the image, much dust is still visible in the air over northern Algeria and moving northward toward Europe. Two low-pressure systems?one centered just northeast of Cape Ortegal, Spain, and the other over the Norwegian Sea?can be seen moving in from the west. (The northern spiral looks horizontally stretched because of the projection used to make this scene.)

| 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 Plumes over Algeria and Niger |
| Description |
Plumes of dust blew through Algeria and Niger on July 31, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture the same day. In the northern- and easternmost portions of this image, buff-colored blurs of dust hide the landscape below. Where dust is absent, the ground appears in shades of tan and brown, with sharp ridges appearing in places. Where it hovers over the land, the dust plume presents a uniform color. Bright white clouds float above the plumes of dust. NASA image courtesy the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC.

| Title |
Dust Storm from the Sahara Desert |
| Description |
On February 21, 2007, a dust storm several hundred kilometers across clogged the skies over Algeria and Mali. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite took this picture the same day. This image shows the dust cloud over the Sahara Desert. As the dust is only slightly lighter than the sand below, the storm is easiest to discern in the east, over more variegated terrain. The Sahara Desert ranks unsurprisingly among the world's most dust-prone regions. Dust from this desert not only crosses national boundaries, but can also travel across the Atlantic Ocean to the Caribbean.

Dust Storm in North Africa
| Title |
Dust Storm in North Africa |
| Description |
A dust storm swept off the north coast of Africa on December 14, 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://aqua.nasa.gov/ ] satellite captured this image the same day. Although the dust swept off the north coast of Libya, it originated in Algeria. In this image, pale beige tendrils of dust swirl from the southwest toward the northeast in Algeria, south of Tunisia, and into Libya. The dust plumes finally dissipate over the Mediterranean north of Libya. Clouds, perhaps part of same weather system that kicked up the dust, obscure the view of the north coasts of Algeria and Tunisia, but most or all of the dust appears to be passing over Libya. As all three of these countries are part of the Sahara Desert, one of the world's most prolific dust producers, dust storms are common in these countries.

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.

Dust Storm over the Sahara
| Title |
Dust Storm over the Sahara |
| Description |
Sand seas, also known as ergs, litter the surface of the Sahara, and these ergs provide ample material for dust storms. This was the case in early October 2006, as a Saharan dust storm crossed the borders between Mauritania, Mali, and Algeria. A sand sea named Erg Chech extends from northern Mali into Algeria, and this sand sea may have provided some of the material for this dust storm. Some of the dust, however, might have originated from other sand seas in the region. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took this picture on October 6, 2006. In this image, the dust appears as a pale beige swirl sweeping through the image in a counter-clockwise direction. Although the storm appears to originate in Mauritania, it also appears to pick up material in northern Mali before moving northeast into Algeria.

Mediterranean Dust Storm |
| Description |
A dust storm was blowing over the Mediterranean Sea from Algeria (left) on August 19, 2003. This image of the storm was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. A few fires have been detected by MODIS and are marked with red dots across Algeria, Tunisia (to the east) and the island of Sardinia (to the northeast). 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.

North African Dust Plume |
| Description |
A dust storm crossed the border between Algeria and Mali on July 14, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took this picture the same day. In this image, the dust appears as a buff-colored blur. Because the dust plume is diffuse, its origins are not easily discerned in this image. In the south, the dust mingles with clouds, and the clouds could be associated with the same weather system that disturbed the desert dust.

Fires in Algeria
| Title |
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.

| Title |
Saharan Dust Across West Africa |
| Description |
A long line of Sahara dust swept across Mali, Mauritania, and Western Sahara and out over the Canary Islands on March 3, 2004. The dust appears to have originated in Algeria. Winter and spring dust storms are common in Western Africa when the sirocco winds, hot, dry, dust-laden winds, blow north and northwest out of the Sahara desert. This image was taken by the Terra [ http://terra.nasa.gov/ ] satellite. Later on the same day, the Aqua [ http://aqua.nasa.gov/ ] satellite recorded a similar scene. As the day progressed, the dust grew thicker and the storm extended farther west. The high resolution image provided above is at MODIS' maximum resolution of 250 meters per pixel. The scene is available in additional resolutions. Image courtesy Jacques Descloitres, MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC |

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 |

Snow over Northern Africa
| Title |
Snow over Northern Africa |
| Description |
Winter weather descended on Northern Africa on January 26 and 27, 2005, leaving parts of Algeria and Morroco white with snow. This rare storm—the worst in over 50 years—brought chaos to the roadways of the normally arid region. As the clouds began to move away on January 28, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured these images of the snow. The top image shows the region in true color, as the human eye would see it. In this image, light clouds blend with the snow-covered ground, making it difficult to tell how much snow is present. The lower image shows the same scene in both visible and short wave infrared light. The infrared bands separate cloud and ice, with cloud appearing peach and orange, and ice and snow appearing dark red. Vegetation is a dark green, while the bare desert is turquoise. In this image, the snow extends from the Mediterranean Coast in the north to the northern reaches of the Sahara Desert in the south.

Flooding in Algeria |
| Description |
Heavy rains in eastern Algeria over the past few weeks have led to flooding that has killed more than 30 people and left hundreds homeless. This false-color image of Algeria (bottom) was taken on August 29, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra satellite. Most of the deaths were due to flash floods in the towns along the Algerian-Tunisian border, which runs down the center of the image. These floodwaters have made their way to the low-lying, desert wetlands of Algeria, clearly visible in the MODIS image (bottom). Although water levels have gone down over the past two days in these oasis-like formations, they normally cannot be seen at all in MODIS imagery (top, acquired on August 6, 2002).

Flooding in Tunisia |
| Description |
In early January 2003 heavy rains in Tunisia have led to floods that have displaced over 3,000 people. The floods can be seen in this false-color image (bottom) acquired on January 19, 2003, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Terra spacecraft. The most devastating floods occurred in the northern and central parts of Tunisia. Most of the houses affected were built of soil and provided ample protection from the normally hot, arid conditions. In the unusually heavy rains and floods of the past few weeks, however, these dwellings simply crumbled. Cattle and food stocks have also been lost. Normally, the salt pans of Tunisia and Algeria contain little or no water (top, acquired January 4, 2003). In this false-color image water is blue and black. Snow, which has also fallen in unusual abundance in the higher altitudes, appears as a bright cyan and can be seen along the Algeria mountains and ridges. Clouds appear as pale blue and white, and land is green and tan. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC |

Floods in Algeria |
| Description |
Torrential rain pounded the Sahara desert of southeastern Algeria in early March 2005. The rainwater poured down the dry channels cut into the desert by former floods, washing away buildings and disrupting telephone and power networks. At least three have died in the floods, and nine others are missing. The water-filled wadis formed blue-green lines through the desert on March 7, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) captured the top image. In both the upper image and the lower image, which has been provided for comparison, clouds are light blue and bare desert soil is tan with a slight pink tint.
