Title 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.

Abstract The Invasive Species Forecasting System (ISFS) is a partnership between NASA and The US Geological Survey (USGS). The ISFS combines NASA Earth observations and statistical models to enhance USGS capabilities to map, monitor and predict the spread of significant invasive plant species. This video shows the habitat suitability for a Tamarisk invasion in the state of California. Tamarisk spreads quickly along riverbeds and when it's leaves shed, they secrete salt on the soil, which can hinder other plant growth. Red indicates areas that are highly suitable. Yellow indicates areas which are less suitable, and grey are areas which are not suitable.

Title Antarctic Plumbing: Lake Englehardt's Subglacial Hydraulic System
Abstract ICESat satellite laser altimeter elevation profiles from 2003-2006 collected over West Antarctica reveal numerous regions of temporally varying elevation. MODIS satellite imagery over roughly the same time period collaborates where these subglacial fluctuations have occurred. These observations have led scientists to conclude that subglacial water movement is happening in this lake region, revealing a widespread, dynamic subglacial water system that could provide important insights into ice flow and the mass balance of Antarctica's ice.

Title Heatwaves and Cold Weather Across Europe
Description While Southern Europe languished in extreme heat, Northern Europe was chilled with cool, fall-like temperatures during the first week of July. Over 30 people died from heat-related illnesses as temperatures soared up to 40 degrees Celsius in Greece, Romania, and Macedonia. During the same period, unseasonably cold weather dominated much of Northern Europe. In Germany?s Bavarian Alps, the thermometer plummeted to -6 Celsius as snow fell in the mountains and high valleys. The contrast between the cold north and the hot south is played out in the above image, which shows an average of daytime land surface temperatures for July 3 through July 10, 2004. A strip of yellow from Romania on the western shores of the Black Sea to the Iberian Peninsula marks out the regions experiencing the highest temperatures. Cooler red and purple covers the rest of Europe, with the coldest temperatures across Scandinavia and Great Britain. Europe?s major mountain ranges separate hot from cold. The Alps cut across northern Italy, their snow-capped peaks forming a line of blue that divides the yellow heat of Italy from the red and purple chill of the lands to the north. In the east, the Carpathian Mountains curve between the red and yellow zones that cover Eastern Europe and the Balkan States, respectively. In the west, a bold red line divides Spain on the Iberian Peninsula and France to its east. The image was created from land surface temperature measurements taken by the Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) onboard NASA?s Aqua and Terra satellites.

Hurricane Daniel
Title Hurricane Daniel
Description Hurricane Daniel formed in the eastern Pacific Ocean on July 16, 2006, off the Mexican coast south of Baja California. The tropical depression strengthened to storm status in the next day, and as the fourth storm in the Eastern Pacific, was named Daniel. By early morning on July 18, winds in the storm reached 120 kilometers per hour (75 miles per hour), bringing Daniel to hurricane strength, just as the previous three storms of the Eastern Pacific had already done in 2006. Like most hurricanes that form in this region, Daniel tracked out into the Pacific farther away from land. It headed west-northwest, where there is little in the way of barriers to its gathering strength, but also little prospect for it to strike inhabited areas. 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 July 18, 2006, at 2:10 p.m. local time (21:10 UTC). Daniel has a very well-defined spiral shape and active thunderstorm systems close to the eyewall. At the time the Aqua satellite passed overhead, Daniel had a closed eye: the center of the storm still had cloud cover. Open-eye hurricanes are generally well-developed and powerful systems, a status that Daniel had not yet achieved, though forecasts called for the hurricane to continue to grow in size and strength over the next few days. Sustained winds in the storm system were estimated to be around 120 kilometers per hour (75 miles per hour) around the time the image was captured, according to the University of Hawaii's Tropical Storm Information Center, [ http://www.solar.ifa.hawaii.edu/Tropical/tropical.html ] very similar to its strength earlier in the day when it first achieved hurricane status. By July 20, though, the apparent pause in the storm's gathering power was long over, and sustained winds were reported to be 200 km/hr (125 mph).

Hurricane Henriette
Title Hurricane Henriette
Description Only the third hurricane of the relatively quiet 2007 eastern Pacific hurricane season, Hurricane Henriette was also the first hurricane of the season to make landfall. Henriette skimmed up the Mexican coastline as it developed between August 30 and September 4, 2007. The National Hurricane Center [ http://www.nhc.noaa.gov/ ] predicted that the storm would come ashore over Baja California on September 4 as a strengthening Category 1 hurricane before traveling north through Mexico and into the United States. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image of Henriette at 2:10 p.m. local time (21:10 UTC) on September 3. At that time Henriette was still a tropical storm with sustained winds of 110 kilometers per hour (70 miles per hour). Though not as powerful as Hurricane Felix, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14483 ] which was pounding Central America from the Caribbean, Henriette had caused at least six deaths in Mexico before coming ashore. The outer bands of the storm inundated Acapulco with heavy rain that caused deadly flooding and landslides, reported the Associated Press on September 4. You can download a 250-meter-resolution KMZ file of Hurricane Henriette [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Sep2007/henriette_amo_2007246.kmz ] suitable for use with Google Earth.

Hurricane Henriette
Title Hurricane Henriette
Description The eastern Pacific hurricane season had been relatively quiet when Hurricane Henriette formed in late August of 2007. Henriette traveled offshore from the Mexican Pacific coast from August 30 to September 4, gradually becoming a Category 1 [ http://www.nhc.noaa.gov/aboutsshs.shtml ] hurricane. The storm had just come ashore over Cabo San Lucas, Baja California, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite acquired this photo-like image at 1:55 p.m. local time (20:55 UTC) on September 4, 2007. Just a few hours before MODIS observed the storm, the National Hurricane Center estimated Henriette's sustained winds to be over 110 kilometers per hour (75 miles per hour), consistent with their Category 1 prediction. The satellite image shows Henriette to have only a loosely wound spiral arm structure and only traces of a central eye. This is consistent with a low-strength hurricane.

Hurricane John
Title Hurricane John
Description As of September 1, 2006, Hurricane John had been lashing Mexico's Pacific coast for several days. The storm system center remained offshore, and forecasts predicted that it would only briefly come ashore as it clipped the southern tip of Mexico's Baja California on its track up the Pacific coast. It is unusual for an eastern Pacific hurricane to come ashore without breaking apart into a lesser storm system because of prevailing wind patterns and cold water upwelling along the coast. Hurricane John, however, managed to run parallel to the Mexico coast for several days. The most powerful hurricane-force winds were not over land, but the Category Four hurricane [ http://www.nhc.noaa.gov/aboutsshs.shtml ] was large enough to bring strong winds and heavy surf to the coastal areas. 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 31, 2006, at 2:10 p.m. local time (20:10 UTC). Hurricane John at the time of this image had a well-defined if widespread shape, spiral-arm structure, and a cloud-filled ("closed") eye. Hurricane John had sustained winds of around 165 kilometers per hour (105 miles per hour) at the time this satellite image was acquired, according to the University of Hawaii's Tropical Storm Information Center. [ http://www.solar.ifa.hawaii.edu/Tropical/tropical.html ] This stregnth was somewhat less powerful than two days earlier when Category 4-strength winds were measured in the central parts of the hurricane.

Hurricane Kenneth
Title Hurricane Kenneth
Description Hurricane Kenneth is just one of a series of tropical storms which have formed in the middle of September 2005 off the coast of Baja California. At the time of this image, it was bracketed by Hurricane Jova to the west and Tropical Storm Max to the east. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image of Kenneth at 3:25 p.m. local time. Kenneth had sustained wind speeds of 210 kilometers per hour (130 miles per hour) and a well-organized spiral structure that is quite apparent in this satellite image.

Hurricane Kenneth
Title Hurricane Kenneth
Description This unusual mosiac of storms shows three well-formed tropical storms in the eastern Pacific off the coast of Baja California, Mexico. They are, from left to right, Hurricane Jova, Hurricane Kenneth, and Tropical Storm Max. Also shown is an intensifying tropical depression which later developed into Tropical Storm Norma, though it had not quite earned the name at the time the Moderate Resolution Imaging Spectrometer (MODIS) made this series of observations. None of the storms are predicted to affect land. The mosaic combines observations spanning the eastern Pacific from Mexico almost all the way to Hawaii. It was created by merging data obtained by both the Terra and Aqua MODIS instruments from two seperate satellite passes each. Small gray gaps show where the MODIS swaths did not quite overlap. These data were obtained by the two MODIS instruments on September 21, 2005, between 11:25 a.m. and 2:35 p.m. Pacific Daylight Time. The high resolution image linked to above is at 500 meter resolution. NASA image created by Jesse Allen, Earth Observatory, using data obtained courtesy of the MODIS Rapid Response team.
