Hurricane Dennis
| Title |
Hurricane Dennis |
| Abstract |
The formation of Hurricane Dennis on July 5 made that the earliest date on record that four named storms formed in the Atlantic basin. Dennis proved to be a powerful and destructive storm in the Caribbean Sea and the Gulf of Mexico. It crossed over Cuba on July 8 and 9, leaving at least 10 dead, and caused additional deaths in Haiti. After re-emerging over open water, Dennis re-strengthened into a dangerous Category 4 hurricane with top wind speeds of 233 kilometers per hour (145 mph). The storm passed within 90 kilometers (55 miles) of Pensacola, Florida, and hit land about 80 kilometers (50 miles) east of where Hurricane Ivan struck in September, 2004. A large storm surge of more than 10 feet was created in certain areas, and many homes and businesses in low-lying areas were flooded. |

Hurricane Emily
| Title |
Hurricane Emily |
| Description |
Hurricane Emily is shown here in the Carribbean north of Venezuela on July 14, 2005. The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite at 17:20 UTC (13:20 Eastern Daylight Time). At this time, it was a well developed and powerful hurricane with winds over 150 kilometers an hour (85 knots). It passed through the chain of islands known as the Windward Islands, causing one death in the city of St. George?s on Grenada. It is building up towards a Category 4 hurricane, the second strongest storm on the Saffir-Simpson intensity scale. Projections take it glancing off Jamaica, striking the Yucatan Peninsula in Mexico, and continuing across into the Gulf of Mexico to make landfall again somewhere near Brownsville, Texas on the border with Mexico and the United States. Predicting hurricane strength and intensity is challenging, and Emily might be either stronger or weaker than expected, and it may not stay on its predicted course. The hurricane has already become somewhat stronger than first anticipated. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team. |

Lake Valencia, Venezuela
| Title |
Lake Valencia, Venezuela |
| Description |
Lago de Valencia (Lake Valencia) is located in north-central Venezuela and is the largest freshwater lake in the country. The lake was formed approximately 2-3 million years ago due to faulting and subsequent damming of the Valencia River. The lake has been completely dry during several discrete periods of its geologic history. Since 1976 Lake Valencia water levels have risen due to diversion of water from neighboring watersheds—it currently acts as a reservoir for the surrounding urban centers (such as Maracay). The vivid green algal blooms present in this image result from a continual influx of untreated wastewater from the surrounding urban, agricultural, and industrial land uses. This contributes to ongoing eutrophication, contamination, and salinization of the lake. Despite its picturesque location between the Cordillera de la Costa to the north and the Serrania del Interior to the south, Lake Valencia's poor water quality limits opportunities for tourism and recreational activities. Astronaut photograph ISS010-E-5194 [ http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS010&roll=E&frame=5194 ] was acquired October 27, 2004 with a Kodak K-760C digital camera with a 180 mm lens and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The International Space Station Program [ http://spaceflight.nasa.gov/ ] supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. [ http://eol.jsc.nasa.gov/ ] |

Oil Slicks on Lake Maracaibo
| Title |
Oil Slicks on Lake Maracaibo, Venezuela |
| Description |
browse image of orbit 16081 (310 KB JPEG) Several oil slicks occurred on Lake Maracaibo in northwestern Venezuela between December 2002 and January 2003, and were observed by various satellite instruments. These images from the Multi-angle Imaging SpectroRadiometer (MISR) provide new information relating to one such event near the center of Lake Maracaibo on December 26, 2002. In unpolluted areas, the water surface is "ruffled" by wind and the resulting wave facets divert reflected rays into many directions. An oil film dampens the presence of small wind-driven "capillary" waves, resulting a smoother, more mirror-like surface. Also, oil is more strongly absorbing than the surrounding water. Therefore, at most viewing angles, a surface slick will appear darker than the surrounding unpolluted areas, whereas near the specular angle (the angle at which a perfect mirror reflects light) it will appear brighter. Simultaneous observation at multiple view angles therefore enhances the reliability of oil-slick detection using optical imaging. An example of how the optical contrast of an oil film on a water surface changes as a function of viewing angle is illustrated by these false-color MISR images, comprised of near-infrared, red and blue spectral data at three different angles, using the vertical-viewing camera (left), the 26ø-forward-viewing camera (center) and the 46ø-forward-viewing camera (right). A swirly area in the middle of the lake appears darker than the surrounding waters at both the nadir and 46° views, but brighter than the surrounding waters at the 26° view. Of the three images, only the 26° camera observes close to specular reflection angle. Lake Maracaibo is the largest lake in South America. The lake is somewhat saline, since it is connected to the Gulf of Venezuela by a narrow strait in the north. Venezuela is the largest oil producing nation in the Western Hemisphere, and the Lake Maracaibo basin includes the largest oil fields and almost a quarter of this nation's population. 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. The MISR Browse Image Viewer [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://eosweb.larc.nasa.gov/MISRBR/ ] provides access to low-resolution true-color versions of these images. These data products were generated from a portion of the imagery acquired during Terra orbit 16081. The panels cover an area of 72 kilometers x 225 kilometers.

| Description |
Unseasonable torrential rains drenched northern South America in February 2005. By February 17, at least 55 had died in floods and mudslides in the mountains of northeastern Colombia, and dozens more had been killed across the border in Venezuela. On February 11, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite detected high water levels on rivers southwest of Lake Maracaibo. The swollen, sediment-laden rivers form a wide blue smudge across the bright green vegetation in the top false-color image. By contrast, more clearly defined river channels were filled with clear, darker water on January 27. In both images, clouds are white and pale blue, while bare earth is pink.

Flooding in Columbia and Venezeula |
| Description |
Though water levels have subsided since mid-February, the Escalante River of southwestern Venezuela and northeastern Colombia was still flooded on February 26, 2005. The floods along this river and others were triggered by days of heavy rain early in February, and resulted in nearly 100 deaths and left thousands homeless throughout both countries. In this image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite, the muddy flood water is light blue. The river covers a broader area than it did on January 27, 2005. In both images, clouds are white and turquoise, plant-covered land is bright green, and deep, clear water is black. Further evidence of flooding can be seen in Lake Maracaibo in the center of the image. Flood water carries dirt into the rivers that empty into the lake. The sediment entering the lake reflects light, which makes the water appear a lighter shade of blue in satellite imagery. While sediment is present in the southwest corner of the lake on January 27, the sediment plume is much brighter and larger on February 26. On both dates, green swirls of duck weed [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12404 ] float on the surface of the lake. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team and the Goddard Land Processes DAAC. |

| Title |
Guiana Highlands, Shaded Relief and Colored Height |
| Original Caption Released with Image |
These two images show exactly the same area in South America, the Guiana Highlands straddling the borders of Venezuela, Guyana and Brazil. The image on the left was created using the best global topographic data set previously available, the U.S. Geological Survey's GTOPO30. In contrast, the image on the right was generated with a new data set recently released by the Shuttle Radar Topography Mission (SRTM) called SRTM30, which represents a significant improvement in our knowledge of the topography of much of the world. GTOPO30, with a resolution of about 928 meters (1496 feet), was developed over a three-year period and published in 1996, and since then has been the primary source of digital elevation data for scientists and analysts involved in global studies. However, since it was compiled from a number of different map sources with varying attributes, the data for some parts of the globe were inconsistent or of low quality. The SRTM data, on the other hand, were collected within a ten-day period using the same instrument in a uniform fashion, and were processed into elevation data using consistent processing techniques. Thus SRTM30 provides a new resource of uniform quality for all parts of the Earth, and since the data, which have an intrinsic resolution of about 30 meters, were averaged and resampled to match the GTOPO30 sample spacing and format, and can be used by the same computer software without modification. The Guiana Highlands are part of the Guyana Shield, which lies in northeast South America and represent one of the oldest land surfaces in the world. Chemical weathering over many millions of years has created a landscape of flat-topped table mountains with dramatic, steep cliffs with a large number of spectacular waterfalls. For example Angel Falls, at 979 meters the highest waterfall in the world, plunges from Auyan Tebuy, part of a mesa of the type that may have been the inspiration for Arthur Conan Doyle's 1912 best-seller "The Lost World." Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking, and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise,Washington, D.C.

Oil Slicks on Lake Maracaibo, Venezuela |
| Original Caption Released with Image |
Several oil slicks occurred on Lake Maracaibo in northwestern Venezuela between December 2002 and January 2003, and were observed by various satellite instruments. These images from the Multi-angle Imaging SpectroRadiometer (MISR) provide new information relating to one such event near the center of Lake Maracaibo on December 26, 2002. In unpolluted areas, the water surface is "ruffled" by wind and the resulting wave facets divert reflected rays into many directions. An oil film dampens the presence of small wind-driven "capillary" waves, resulting a smoother, more mirror-like surface. Also, oil is more strongly absorbing than the surrounding water. Therefore, at most viewing angles, a surface slick will appear darker than the surrounding unpolluted areas, whereas near the specular angle (the angle at which a perfect mirror reflects light) it will appear brighter. Simultaneous observation at multiple view angles therefore enhances the reliability of oil-slick detection using optical imaging. An example of how the optical contrast of an oil film on a water surface changes as a function of viewing angle is illustrated by these false-color MISR images, comprised of near-infrared, red and blue spectral data at three different angles, using the vertical-viewing camera (left), the 26°-forward-viewing camera (center) and the 46°-forward-viewing camera (right). A swirly area in the middle of the lake appears darker than the surrounding waters at both the nadir and 46° views, but brighter than the surrounding waters at the 26° view. Of the three images, only the 26° camera observes close to specular reflection angle. Lake Maracaibo is the largest lake in South America. The lake is somewhat saline, since it is connected to the Gulf of Venezuela by a narrow strait in the north. Venezuela is the largest oil producing nation in the Western Hemisphere, and the Lake Maracaibo basin includes the largest oil fields and almost a quarter of this nation's population. 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. These data products were generated from a portion of the imagery acquired during Terra orbit 16081. The panels cover an area of 72 kilometers x 225 kilometers, and utilize data from blocks 81 to 83 within World Reference System-2 path 8. 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. |

Flooding Resulting From Hurricane Isidore, Comparing Data from September 12 and 28, 2002 |
| Original Caption Released with Image |
Extent of Flooding due to Hurricane Isidore revealed in images from the Atmospheric Infrared Sounding System (AIRS) on Aqua Tropical Storm Isidore was born in mid-September north of Venezuela. It subsequently hit Mexico's Yucatan Peninsula as a Category 3 hurricane and came ashore near New Orleans on September 26th packing winds just below hurricane strength. Around the time of September 27, the storm was downgraded to a tropical depression as the system moved into Tennessee. At the time the Aqua spacecraft first passed over Isidore, it was classified as a Category 3 (possibly 4) hurricane, with minimum pressure of 934 mbar, maximum sustained wind speeds of 110 knots (gusting to 135) and an eye diameter of 20 nautical miles. Isidore was later downgraded to a Tropical Storm and then a Tropical Depression as it lost energy. Figures 1 and 2, two images from the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellites show no significant weather systems over the southeastern United States on September 12 and September 28 (16 days apart). However, the microwave component of the Atmospheric Infrared Sounder Experiment on NASA's Aqua spacecraft shows a striking difference. The difference in the two microwave images (figures 3 and 4) from the AIRS Advanced Microwave Sounding Unit is primarily due to flooding after Tropical Storm Isidore. Water has a very low surface emissivity at this frequency, and that causes surface water to appear very cold (even though it is not). Land appears relatively warm (well above freezing - 273 K, even at night as seen is these images), but if there is standing water, the apparent temperature drops precipitously. Figure 4, taken just about a day after the remnants of Isidore passed over the southeast, shows heavy flooding along the Mississippi, especially in the states of Mississippi and Tennessee, but other states are also affected. The spatial resolution of the AMSU-A instrument is relatively large (each measurement spot is about 25 miles in diameter at the center of the swath), but the enormous thermal contrast in the microwave between land and water makes even small flooded areas stand out., Figure 5: Difference image, 9/12 and 9/28) The Aqua spacecraft has an exact 16-day repeat cycle, that is why the pre-Isidore image is 16 days prior to the post-Isidore image. They have exactly the same coverage, which makes it possible to obtain a difference image (figure 5). The difference image is the difference between the September 28 and September 12 images shown. In the difference image, white indicates no difference at all, green is very little difference, blue/purple indicates primarily heavy flooding. Red indicates warming likely due to warmer weather. (The straight lines on the right and left edges of the difference image are caused by slight differences between the two repeat passes of Aqua). The Atmospheric Infrared Sounder Experiment, with its visible, infrared, and microwave detectors, provides a three-dimensional look at Earth's weather. Working in tandem, the three instruments can make simultaneous observations all the way down to the Earth's surface, even in the presence of heavy clouds. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, 3-D map of atmospheric temperature and humidity and provides information on clouds, greenhouse gases, and many other atmospheric phenomena. The AIRS Infrared Sounder Experiment flies onboard NASA's Aqua spacecraft and is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., under contract to NASA.

View of the Caribbean coast of Venezuela |
| Description |
A near vertical view of the Caribbean coast of Venezuela is seen in this Skylab 3 Earth Resources Experiment Package S190-B (five-inch earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The large body of water is the Golfo de Venezuela, and the major land mass is the Peninsula de Paraguana. The view is looking northward from the mouth of the Golfete de Coro and Punta Cardon to Punta Macolia. The peninsula is connected to the Venezuelan mainland by the narrow strip of land in the most easterly corner of the picture. The dry, arid climate of the peninsula is indicated by sparse vegetation and the abundance of sand dunes. The highest point is about 2,700 feet above the sea and is the conspicuous black spot. Old raised shorelines features appear as streaks parallel to the Golfete de Coro. Water of the Golfete de Coro is red from the high sediment content. The streaks in the water off the peninsula is apparently an effect of wind which is blowing sand and w |
