National Map Showing Habitat Suitability for Tamarisk Invasion |
| Abstract |
The spread of invasive species is one of the most daunting environmental, economic, and human-health problems facing the United States and the World today. It is one of several grand challenge environmental problems being addressed by NASA's Science Mission Directorate through a national application partnership with the US Geological Survey. NASA and USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species on Department of Interior and adjacent lands. The system provides a framework for using USGS's early detection and monitoring protocols and predictive models to process MODIS, ETM+, ASTER and commercial remote sensing data, to create on-demand, regional-scale assessments of invasive species likely habitats. Recent work on the Invasive Species Forecasting System (ISFS) project has shown the importance of remotely-sensed time-series data in geostatistical models for mapping the distribution of Tamarisk and other invasive plant species. This video shows the habitat suitability for a Tamarisk invasion in the continental United States. Red indicates areas that are highly suitable and yellow indicates areas which are less suitable. Texas, New Mexico, and Nevada are the most highly suitable states. Utah and Arizona have the next greatest risk. California, Arizona, Montana, Colorado, Oregon, Ohio, Wyoming, and Florida also have a significant risk. |

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 Dennis |
| Description |
More than a million people are evacuating the coastal areas of Florida and Alabama as Hurricane Dennis steadily approaches. The first hurricane of the 2005 Atlantic hurricane season, Dennis has already been a deadly storm. 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 3 hurricane with winds approaching 115 miles per hour when this image was taken at 2:45 p.m. EDT on July 9, 2005. The Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov/ ] on NASA?s Aqua [ http://www.aqua.nasa.gov/ ] satellite captured this image of the storm sliding up Florida?s west coast. The National Hurricane Center warns that Dennis continues to strengthen and may become a powerful Category 4 hurricane before making landfall over the northern Gulf Coast on July 10. For additional information and warnings about this storm, please visit the National Hurricane Center. This image is available in additional resolutions from the MODIS Rapid Response Team.

Dust Storm Off the Coast of Western Africa |
| Description |
On May 16, 2005, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ], flying onboard the Aqua [ http://www.aqua.nasa.gov/ ] satellite, captured this image of a dust storm off the West Coast of Africa sprawling toward the Cape Verde Islands. Dust storms often cross the Atlantic entirely, bringing mixed blessings to the Americas. Residents of Florida may suffer more respiratory illnesses, and the dust sometimes carries microorganisms that harm Caribbean coral reefs. However, the dust also brings iron and other nutrients that benefit marine and terrestrial ecosystems.

Hurricane Katrina |
| Description |
Hurricane Katrina was sprawled across all or part of 16 states at 2:15 p.m. CDT on August 29, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. After nearly eight hours over land, Katrina was still a Category 1 storm, with winds of 150 kilometers per hour (95 miles per hour) and stronger gusts. In this image, Katrina measures about 1,260 kilometers (780 miles) from east to west and about the same distance from north to south across its center. While most states under its clouds have only experienced rain so far, Louisiana, Mississippi, Alabama, and Florida have all been pummeled by furious winds, heavy rain, and a powerful storm surge. Katrina was a strong Category 3 storm when its eye moved ashore earlier in the day. The large image provided above has a resolution of 500 meters per pixel. The MODIS Rapid Response Team provides the image in additional resolutions, including MODIS' maximum resolution of 250 meters per pixel.

Hurricane Katrina Floods the Southeastern United States |
| Description |
Though still a weak hurricane at the time, Hurricane Katrina dumped heavy rain on the southern tip of Florida on August 25 and August 26, 2005. On August 28, a few clouds lingered over Florida, but the storm had moved away to reveal extensive flooding. These false-color images were taken by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] and Terra [ http://terra.nasa.gov/ ] satellites. In this color combination, water appears black, vegetation appears bright green, and clouds are pale blue and white. The most visible flooding is in Everglades National Park. The park's boundaries are clearly visible in the lower image, taken on August 8, 2005. The northeastern boundary of the park is defined by a bright green line formed by the Highway 41 corridor. On the east side of the peninsula, the land is a lighter green where the water has been drained away and the land cultivated. Numerous cities, including Miami, dot the landscape with patches of cement-colored gray. Everglades National Park surrounds the developed land to the south and west and is defined by the deeper green of native vegetation and swampland. On August 28, top, water filled much of the park, but there is little sign of flooding to the east. Extensive flooding was reported in southeastern Florida, but it is not visible in this image. The effects of Hurricane Katrina on the ocean are clear. As the storm passed, its rains and wind churned the ocean, bringing clouds of sediment to the surface. This sludge from the ocean floor colors the water an electric blue in the top image. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel.

Hurricane Ophelia
| Title |
Hurricane Ophelia |
| Description |
Over the last several days, Ophelia has meandered off of the southeast coast of the United States. The storm system, which began as a depression over the Bahamas on September 6, 2005, has twice stalled out and made loops: once just east of Cape Canveral, Florida, and the other farther out to sea east of Georgia. Ophelia has also flip-flopped several times between a strong tropical storm and a weak Category 1 hurricane. Despite its very slow movement, which usually leads to weakening due to upwelling of cooler water, Ophelia has maintained itself as a result of warm waters an its proximity to the Gulf Stream. The hurricane was grazing along the North Carolina coastline without making landfall when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 2:20 p.m. Eastern time on September 15, 2005. At the time, Ophelia had winds of 120 kilometers per hour (75 miles per hour), easing off slightly from its latest peak and heading back down yet again to tropical storm status. The slow-moving storm was initially forecasted to dump heavy rain on the Outer Banks of North Carolina, but proved less destructive than feared. One death (due to a car accident in Raleigh attributed to slick roads) has been attributed to the storm, but fears of substantial flooding have largely not been realized. The large image provided above has a resolution of 250 meters per pixel. The image is available in additional resolutions from the MODIS Rapid Response Team.

Hurricane Ophelia
| Title |
Hurricane Ophelia |
| Description |
Tropical Storm Ophelia gathered strength and size off the Atlantic Coast of Florida for several days. During this time, it brought winds and rain over a growing area including the Florida coast, though the storm's center remained offshore. By September 8, it briefly reached hurricane strength, though this status lasted only a few hours before the storm lost some intensity and was again classified as a tropical storm. It is unusual for a storm system to build just offshore in this fashion, especially as having rain bands over land tends to break up the storm formation. It is also unusual to have so many storms in such a short time: the 2005 Atlantic hurricane season looks likely to go into the record books as the most active season on record yet. Ophelia is the earliest "O" named storm since the storm naming system was devised. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 2:15 p.m. local time, on September 8, 2005. At that time, Ophelia had peak sustained wind speeds of around 120 kilometers per hour (75 miles per hour). The large image provided above has a spatial resolution of 250 meters per pixel. It is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2005251-0908/Ophelia.A2005251.1815 ] from the MODIS Rapid Response Team.

Hurricane Rita
| Title |
Hurricane Rita |
| Description |
After the immense devastation brought by Hurricane Katrina, all eyes were on Hurricane Rita as it passed over the Florida Keys and the Gulf of Mexico. Rita formed from a tropical disturbance east of the Turks and Caicos Islands into a depression (TD #18) on September 17, 2005. The system moved west through the Caicos and strengthened into a tropical storm on the 18th before entering into the southern Bahamas. Category 2 Hurricane Rita was passing between the Florida Keys and Cuba when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 2:35 p.m. Eastern time on September 20, 2005. At the time, Rita had peak sustained winds of 160 kilometers per hour (100 miles per hour), with hurricane-strength winds extending well away from the storm's center, including settlements in the Key Islands and in Cuba's capital, Havana. The large image provided above has a resolution of 250 meters per pixel. The image is available in additional resolutions from the MODIS Rapid Response Team.

Hurricane Wilma |
| Description |
*Hurricane Wilma* Hurricane Wilma had just crossed Florida when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on October 24, 2005, at 2:25 p.m. Eastern Daylight Time. The storm made landfall eight hours earlier, at about 6:30 a.m., near Naples, Florida. At the time, Wilma was a strong Category 3 storm with winds gusting to 200 kilometers per hour (125 miles per hour). The storm weakened as it crossed Florida, but regained strength as it re-emerged over the Atlantic. By the time this image was taken, Wilma was back up to Category 3 status with winds of 185 km/hr (115 mph) and gusts to 210 km/hr (130 mph). Early news reports say that Wilma has brought widespread coastal flooding and wind damage to southern Florida. The large image provided above has a resolution of 250 meters per pixel, MODIS' maximum resolution. The image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2005297-1024/Wilma.A2005297.1825 ] from the MODIS Rapid Response Team.

| Title |
Sahara Dust Cloud |
| Original Caption Released with Image |
"" Dust Particles Click on the image for Quicktime movie from 7/15-7/24 A continent-sized cloud of hot air and dust originating from the Sahara Desert crossed the Atlantic Ocean and headed towards Florida and the Caribbean. A Saharan Air Layer, or SAL, forms when dry air and dust rise from Africa's west coast and ride the trade winds above the Atlantic Ocean. These dust clouds are not uncommon, especially during the months of July and August. They start when weather patterns called tropical waves pick up dust from the desert in North Africa, carry it a couple of miles into the atmosphere and drift westward. In a sequence of images created by data acquired by the Earth-orbiting Atmospheric Infrared Sounder ranging from July 15 through July 24, we see the distribution of the cloud in the atmosphere as it swirls off of Africa and heads across the ocean to the west. Using the unique silicate spectral signatures of dust in the thermal infrared, AIRS can detect the presence of dust in the atmosphere day or night. This detection works best if there are no clouds present on top of the dust, when clouds are present, they can interfere with the signal, making it much harder to detect dust as in the case of July 24, 2005. In the Quicktime movie, the scale at the bottom of the images shows +1 for dust definitely detected, and ranges down to -1 for no dust detected. The plots are averaged over a number of AIRS observations falling within grid boxes, and so it is possible to obtain fractional numbers. "" Total Water Vapor in the Atmosphere Around the Dust Cloud Click on the image for Quicktime movie The dust cloud is contained within a dry adiabatic layer which originates over the Sahara Desert. This Saharan Air Layer (SAL) advances Westward over the Atlantic Ocean, overriding the cool, moist air nearer the surface. This burst of very dry air is visible in the AIRS retrieved total water vapor product as a region of depressed water vapor (brown in the images) migrating slowly Westward toward the Caribbean. The SAL phenomenon inhibits the formation of tropical cyclones and thus has given the West Indies and the East Coast of the US a respite from hurricanes. 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. JPL is a division of the California Institute of Technology in Pasadena. |

"" Dust Particles Click on the image for Quicktime movie from 7/15-7/24 A continent-sized cloud of hot air and dust originating from the Sahara Desert crossed the Atlantic Ocean and headed towards Florida and the Caribbean. A Saharan Air Layer, or SAL, forms when dry air and dust rise from Africa's west coast and ride the trade winds above the Atlantic Ocean. These dust clouds are not uncommon, especially during the months of July and August. They start when weather patterns called tropical waves pick up dust from the desert in North Africa, carry it a couple of miles into the atmosphere and drift westward. In a sequence of images created by data acquired by the Earth-orbiting Atmospheric Infrared Sounder ranging from July 15 through July 24, we see the distribution of the cloud in the atmosphere as it swirls off of Africa and heads across the ocean to the west. Using the unique silicate spectral signatures of dust in the thermal infrared, AIRS can detect the presence of dust in the atmosphere day or night. This detection works best if there are no clouds present on top of the dust, when clouds are present, they can interfere with the signal, making it much harder to detect dust as in the case of July 24, 2005. In the Quicktime movie, the scale at the bottom of the images shows +1 for dust definitely detected, and ranges down to -1 for no dust detected. The plots are averaged over a number of AIRS observations falling within grid boxes, and so it is possible to obtain fractional numbers. "" Total Water Vapor in the Atmosphere Around the Dust Cloud Click on the image for Quicktime movie The dust cloud is contained within a dry adiabatic layer which originates over the Sahara Desert. This Saharan Air Layer (SAL) advances Westward over the Atlantic Ocean, overriding the cool, moist air nearer the surface. This burst of very dry air is visible in the AIRS retrieved total water vapor product as a region of depressed water vapor (brown in the images) migrating slowly Westward toward the Caribbean. The SAL phenomenon inhibits the formation of tropical cyclones and thus has given the West Indies and the East Coast of the US a respite from hurricanes. 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. JPL is a division of the California Institute of Technology in Pasadena. |
