| Title |
Floods in Turkey, Greece, Bulgaria |
| Description |
Days of heavy rain triggered floods across parts of western Turkey, eastern Greece, and southeastern Bulgaria in November 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of floods in the border region of the three countries on November 22. The Evros River, called the Meriç River in Turkey, flows from Bulgaria south along the border between Turkey and Greece and into the Aegean Sea. Normally visible only by the strip of green that lines the river's banks, the river paints a wide blue line along the border. Flowing into the Evros/Meriç from the east, the Ergene River is similarly flooded, as are a number of other tributaries, including the Ardas. Both the November 22 image and the November 9 image (provided to show the rivers under normal conditions) were made with a combination of visible and infrared light. This combination allows water, even murky flood water, to stand out from the land. Water is black, though in this case, mud colors the water blue. Reminders of the storm that caused the floods, white and pale blue clouds are scattered over the flood scene. Plant-covered land is bright green, and bare earth is tan. The bare rocks of the mountainous landscape were brick red on November 9, but at least partly covered over by plants by November 22. Hundreds of homes and businesses flooded in the Evros region of Greece, forcing the evacuation of two villages, said the Dartmouth Flood Observatory. [ http://www.dartmouth.edu/%7efloods/Archives/2007sum.htm ] Outside of the area shown in this image, additional flooding inundated the cities of Bodrum and Marmaris in western Turkey and the Montana region of Bulgaria.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/fas/?Europe_3_03/2007326 ] of Turkey, Greece, and Bulgaria are available from the MODIS Rapid Response System.

| Title |
Dust Plume off the Coast of Northern Africa |
| Description |
Dust blew off the African coast and over the Mediterranean Sea on June 9, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite captured this image the same day. In this image, the opaque tan dust plume billows off the coast, along the Libya-Egypt border, in a shape vaguely resembling a giant inverted teardrop. Directly north of the dust plume lies the island of Kriti (Crete). North of that, much smaller islands dot the Aegean Sea. Pale streamers sweep southward from these islands, from a cause that appears unrelated to the dust plume. The streamers may be "wind shadows" on the ocean surface highlighted by sunglint that results from the Sun's light bouncing off the water's surface and into the satellite sensor. You can download a 250-meter-resolution KMZ file [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Jun2007/nafrica_tmo_2007160.kmz ] of the dust storm for use with Google Earth.

Summer Aerosols over Greece |
| Original Caption Released with Image |
Strong synoptic winds usually help to disperse pollutants over the skies of Greece and the Aegean Sea during winter months, and in late summer relatively strong northerly winds typically prevent significant aerosol influx from the south. During the summer of 2002, the northerly Etesian winds were exceptionally weak, allowing Sahara dust from the south to reach the Aegean region. This resulted in elevated aerosol levels, particularly in the month of July. The abundance of aerosol over Greece and the Aegean Sea on four dates during the summer of 2002 are illustrated by these images from the Multi-angle Imaging SpectroRadiometer (MISR). In the natural-color images (the left-hand panel of each pair), it is apparent that aerosol particles are more abundant over the region on the two dates in July than in either June or August. These natural-color views were acquired by MISR's 70-degree forward-viewing camera. The top and bottom views depict overlapping parts of mainland Greece and the Aegean, with the bottom panels covering a region to the west of the top panels. Data from each of the four dates have been processed identically, and relative brightness variations between the views are preserved. MISR retrieves information on aerosol amount and particle properties by using the changes in scene brightness and contrast at nine widely-spaced view angles and four spectral bands. The right-hand panel of each image pair is a map of retrieved aerosol amount, parameterized by a quantity called aerosol optical depth. A color scale is used to represent this quantity. Higher amounts of aerosol within the total column of the atmosphere are indicated by green, yellow or orange pixels, and clearer skies are indicated by purple and blue pixels. Dark gray pixels indicate places where clouds or other factors precluded an aerosol retrieval. 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 Terra orbits 13325, 13558, 13660 and 14126. The panels utilize data from blocks 59 to 62 within World Reference System-2 paths 182 and 183. 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. |

Islands in the Midst of the World |
| Original Caption Released with Image |
The Greek islands of the Aegean Sea, scattered across 800 kilometers from north to south and between Greece and western Turkey, are uniquely situated at the intersection of Europe, Asia and Africa. This image from the Multi-angle Imaging SpectroRadiometer includes many of the islands of the East Aegean, Sporades, Cyclades, Dodecanese and Crete, as well as part of mainland Turkey. Many sites important to ancient and modern history can be found here. The largest modern city in the Aegean coast is Izmir, situated about one quarter of the image length from the top, southeast of the large three-pronged island of Lesvos. Izmir can be located as a bright coastal area near the greenish waters of the Izmir Bay, about one quarter of the image length from the top, southeast of Lesvos. The coastal areas around this cosmopolitan Turkish city were a center of Ionian culture from the 11th century BC, and at the top of the image (north of Lesvos), once stood the ancient city of Troy. The image was acquired before the onset of the winter rains, on September 30, 2001, but dense vegetation is never very abundant in the arid Mediterranean climate. The sharpness and clarity of the view also indicate dry, clear air. Some vegetative changes can be detected between the western or southern islands such as Crete (the large island along the bottom of the image) and those closer to the Turkish coast which appear comparatively green. Volcanic activities are evident by the form of the islands of Santorini. This small group of islands shaped like a broken ring are situated to the right and below image center. Santorini's Thera volcano erupted around 1640 BC, and the rim of the caldera collapsed, forming the shape of the islands as they exist today. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously from pole to pole, and views almost the entire globe every 9 days. This natural-color image was acquired by MISR's nadir (vertical-viewing) camera, and is a portion of the data acquired during Terra orbit 9495. The image covers an area of 369 kilometers x 567 kilometers, and utilizes data from blocks 58 to 64 within World Reference System-2 path 181. 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. |
