Haitian Deforestation
Title Haitian Deforestation
Abstract The border between Haiti and the Dominican Republic (D.R.) is more than just a political boundary. It also reflects the large amount of deforestation that has occurred on the Haitian side of the border. One can easily see from satellite imagery the lush forests still thriving on the D.R. side of the border, which is in sharp contrast to the Haitian side of the border.

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.

Floods in Gonaives, Haiti
Title Floods in Gonaives, Haiti
Description The floods that claimed the lives of at least 1,500 Haitians and left as many missing, also filled a large lake basin outside of Gonaives. The basin, which was a dry dust bowl on August 8, 2001, was still completely covered with water on October 3, 2004, two weeks after Hurricane Jeanne's heavy rains induced the flooding. Some of the water may have been present before the floods, but the recent influx of water has pushed the lake far beyond its shores. According to the Associated Press, the lake has covered the primary road connecting Gonaives to Haiti's capital, Port-au-Prince, with over a meter (four feet) of water, making food delivery difficult. The road can be seen here, a blurred white line under the dark blue water. The grey area at the end of the road near the shore is Gonaives. These images were acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER [ http://asterweb.jpl.nasa.gov/ ]). They were made by combining the infrared, near infrared, and red wavelengths (ASTER bands 4, 3, & 2). In this treatment, bare land appears pink, healthy croplands are light green, and concrete structures such as city buildings have a grey or deep purple tone.

Hurricane Ernesto
Title Hurricane Ernesto
Description Hurricane Ernesto formed in the eastern Caribbean Sea on August 24, 2006. Within a day, it had become organized enough to be classified as a tropical storm and get named as the fifth storm of the 2006 Atlantic hurricane season. Ernesto built in power gradually as it moved westward and slightly north through the Caribbean Sea, just reaching hurricane strength on August 27 as it neared Hispaniola, the island on which the nations of Haiti and Dominican Republic are located. Ernesto was the first storm of the 2006 Atlantic season to reach hurricane strength. The storm's interaction with land robbed it of enough power to diminish it back to "tropical storm" status, but predictions as of August 29 are that favorable conditions north of Cuba may allow it to re-intensify to hurricane status before it comes ashore in southern Florida. This photo-like image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on the Aqua [ http://aqua.nasa.gov/ ] satellite on August 28, 2006, at 2:00 p.m. local time (18:00 UTC). Tropical Storm Ernesto at the time of this image was a well-developed storm system, but its interactions with Hispaniola and Cuba had distorted the former hurricane, disrupting its shape enough to prevent the formation of a well-defined eye. The spiral-arm cloud structure was also not as distinct as it would be in a well-developed hurricane. According to the University of Hawaii's Tropical Storm Information Center, [ http://www.solar.ifa.hawaii.edu/Tropical/tropical.html ] Ernesto had sustained peak winds of around 65 kilometers per hour (40 miles per hour) at the time Aqua MODIS acquired these data.

Hurricane Ernesto
Title Hurricane Ernesto
Description On Sunday August 27, 2006, Ernesto became the first storm of the Atlantic season to reach hurricane intensity. Ernesto did not maintain hurricane intensity for long, however, and was soon downgraded back to a tropical storm after grazing the southwestern tip of Hispaniola. Ernesto formed from an easterly wave—a low-pressure ripple in the atmosphere—that moved west across the Atlantic and into the Caribbean. After passing through the Windward Islands, the wave developed into the fifth tropical depression of the year on August 24. This series of images shows the development of the storm. The earliest image (bottom image in the trilogy) shows the storm in the southeastern Caribbean soon after it had formed. The image was taken 10:41 p.m. local time on August 24, 2006, (02:41 UTC on August 25) by the Tropical Rainfall Measuring Mission (TRMM) [ http://trmm.gsfc.nasa.gov/ ] satellite. Rain rates in the center swath are from the TRMM Precipitation Radar, while those in the outer swath are from the TRMM Microwave Imager. The rain rates are overlaid on infrared data from the TRMM Visible Infrared Scanner. Scattered areas of light (blue) to moderate (green) rain and little evidence of classic hurricane organization reveal that the system was still in its early stages of development. The storm developed into Tropical Storm Ernesto the next day, when the middle image in the series was taken. As the system tracked west-northwest, it encountered southwesterly winds at higher altitudes, a pattern that tends to shear off the tops of developing storms and to prevent them from gathering strength. These winds kept the storm from gaining much strength despite warm sea surface temperatures. Warm water is the engine that drives tropical storms. When this image was taken at 7:34 a.m. local time (11:34 UTC) on August 26, Ernesto was passing south of the Dominican Republic. At that time, intense areas of rain were present within the storm (red areas). However, Ernesto still did not have a visible eye, nor a particularly well-developed circulation, the spiraling band of clouds typically associated with tropical storms and hurricanes. At that time, the National Hurricane Center [ http://www.nhc.noaa.gov/ ], reported that Ernesto's maximum sustained winds were 74 kilometers per hour (46 miles per hour). Throughout the day, Ernesto continued to encounter high-altitude winds from the southwest that pushed the storm's top eastward, creating the elongated oval shape seen in the top image. This image was obtained at 10:24 p.m. local time on August 26 (02:24 UTC, August 27), when Ernesto was approaching Haiti. Although the center of the storm did not fall within the center of the TRMM instruments' fields of view, the rainfall pattern confirms that high-altitude winds were still confining the heaviest rains to the eastern side of the storm. At the time of this image, Ernesto's sustained winds were up slightly to 92 km/hr (58 mph). During the night of August 26, the shear across Ernesto finally eased off, and the storm responded by intensifying into a Category 1 hurricane. However, by this time, Ernesto was close to southwestern Haiti. Ernesto crossed the southwestern tip of Haiti on August 27, which caused it to weaken back to a tropical storm. Ernesto then continued northwest before making landfall in southeastern Cuba several hours later. As of August 29, Ernesto remained a somewhat disorganized tropical storm system. The storm was expected to reorganize as it left Cuba, but it was unclear if it would have enough time to develop back to hurricane strength before making a projected landfall in south Florida. The TRMM satellite was placed into service in November 1997. From its low-earth orbit, TRMM provides valuable images and information on storm systems around the tropics using a combination of passive microwave and active radar sensors, including the first precipitation radar in space. TRMM is a joint mission between NASA and the Japanese space agency, JAXA. Images produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).
Fires on Hispaniola
Title Fires on Hispaniola
Description A thick pall of smoke hung over several thousand square kilometers in the Central Mountains of the Dominican Republic on March 24, 2005, when this image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. Even through the smoke, MODIS detected several actively burning fires (red dots). March is typically a dry month for the island of Hispaniola, which is home to Haiti as well. As of March 25, the cause of the fires, which began in a national park near Pico Duarte, the island's highest peak, had not been reported.

Tropical Storm Alpha
Title Tropical Storm Alpha
Description While Hurricane Wilma was bringing high winds and rain to western Cuba, newly formed Tropical Storm Alpha was raining on eastern Cuba and the island of Hispaniola. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took this image at 1:40 p.m. Eastern Daylight Time, on October 23, 2005. At this time, Alpha had developed into a tropical storm and was weakening back into a less-powerful tropical depression, even though some of the spiral structure characteristic of tropical storms can be seen in this image. Sustained winds in the storm ran as high as 55 kilometers per hour (35 miles per hour), and the storm brought substantial rains to the area. This heavy rain was responsible for three deaths reported in Haiti, in which individuals were drowned when flash flooding overwhelmed them. Alpha is the 22nd named storm of the 2005 hurricane season, exhausting the entire alphabetical list of names chosen by the National Hurricane Center. (Letters for which there are only a few possible names, such as "X" and "Q", are not used in the list of names). The naming system moves on to naming storms by letters of the greek alphabet (alpha, beta, gamma, and so on). This season is the first time this part of the naming system has been called into use.

As of November 2, 79 people had been reported dead and 65,000 displaced in the Dominican Republic, said the United Nations Office for the Coordination of Humanitarian Affairs. [ http://www.reliefweb.int/rw/rwb.nsf/db900sid/EGUA-78KQAQ?OpenDocument&rc=2&emid=TC-2007-000198-DOM ] The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of floods near the northern shore of the Dominican Republic on November 1. The image was made with a combination of infrared and visible light so that water is black, plant-covered land is bright green, and clouds are pale blue and white. Run-off from the floods filled the Yuna River with sediment, coloring the water blue. The sediment also colors the Atlantic Ocean near the mouth of the river. As the lower image shows, the Yuna River is not visible in MODIS imagery under normal conditions, but in the November 1 image, the river has swollen enough to be clearly seen beneath a thin veil of clouds. The flooded delta covers several kilometers.

Floods in Gonaives, Haiti
Title Floods in Gonaives, Haiti
Description *Floods in Gonaives, Haiti* The wall of water that descended on Gonaives, Haiti, following Tropical Storm Jeanne on September 18, 2004, also scoured out a broad channel in the landscape. The violence of the floods is apparent in the above false-color images, acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) before and after the floods. The rush of water has left a silvery path of gravel and mud that is as much as 500 meters wide starting about 15 kilometers upstream of the city. As the water approached the less mountainous coast where Gonaives is located, it fanned out over the plain. The primary path of the flood seems to take the water into Gonaives and the land to its immediate north. In the pre-flood image, acquired on August 8, 2001, the city is the gray region in the lower left corner. In the image acquired on September 26, 2004, the city is obscured by the blue-green sediment left by the flood water. To the east of Gonaives, some of the flood water has filled a lake basin, the top of which is visible in the lower right corner of the image. The thin white line across the bottom of the image is a road leading to Gonaives. The road has been submerged in the lake basin, though is still visible beneath the dark blue water. In these false-color images, vegetation is bright red and water is black. Bare land is white and light blue. Clearly the hills around the city are bare, one of the primary reasons for the floods. Without trees to slow and absorb rainfall, the water rushed into depressions in the land and poured to the ocean beyond Gonaives.

Title Hurricane Jeanne Cloud Height and Motion
Original Caption Released with Image After causing widespread destruction on Puerto Rico, Haiti and the Dominican Republic, Hurricane Jeanne was weakened to Tropical Storm status for several days before it regained strength over the Bahamas as a Category 2 hurricane. When Jeanne made landfall in U.S. territory on September 26 it was the fourth major hurricane of the 2004 Atlantic hurricane season to strike Florida. These visualizations of Hurricane Jeanne on September 24 were captured by NASA's Multi-angle Imaging SpectroRadiometer (MISR). The still panels include a natural color view from MISR's 26-degree forward-viewing camera (left) and a two dimensional map of cloud-top heights (right). In addition, a "multi-angle fly-over" is provided as an animation using views from all nine MISR cameras. The nine camera views which make up the animation have been processed to give an approximate perspective view. The animation makes visible the relative heights of clouds within the scene. Some of the real cloud motion over the seven minutes during which all nine MISR cameras observed the scene are also indicated by the animation. The cloud height map was produced by automated computer recognition of the distinctive spatial features between images acquired at different view angles. Two-dimensional maps of cloud height such as these offer an opportunity to compare simulated cloud fields against actual hurricane observations. Results indicate that clouds within Jeanne had attained altitudes of more than 16 kilometers above sea level. The height field pictured here is uncorrected for the effects of cloud motion. Wind-corrected heights have higher accuracy but sparser spatial coverage. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82° north and 82° south latitude. These data products were generated from a portion of the imagery acquired during Terra orbit 25372. The still image panels cover an area of about 400 kilometers x 884 kilometers, and utilize data from within blocks 68 to 71 and within World Reference System-2 path 10. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.
