Hurricane Isidore
Description Hurricane Isidore
Full Description A view of Hurricane Isidore from the Atmospheric Infrared Sounding System (AIRS) on Aqua. At the time Aqua 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 before gathering strength again. This is a visible/near-infrared image, made with the AIRS instrument. Its 2 km resolution shows fine details of the cloud structure, and can be used to help interpret the other images. For example, some relatively cloud-free regions in the eye of the hurricane can be distinguished. This image was made with wavelengths slightly different than those seen by the human eye, causing plants to appear very red. In the near future, weather data derived from these images will allow us to improve our forecasts and track the paths of hurricanes more accurately. The AIRS sounding system provides 2400 such images, or channels, continuously. 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. *Image Credit:* NASA/JPL

Title Aqua/AIRS Water Vapor near southern California #2
Abstract This visualization shows 3D volumetric water vapor data from the Aqua/Atmospheric Infrared Sounder (AIRS) instrument. As the camera moved down and around the data set, the low data values are faded out revealing only the highest concentrations of water vapor data. This version (#2) ends with a slightly lower threshold than the original version - showing more of the highest water vapor concentrations. The color and opacity at each 3D voxel are driven by the water vapor data. The data set was obtained by Aqua on January 1, 2003. Only data from the sea level to about 10km are shown. This visualization was created to support a JPL press release about how assimilated AIRS data is improving global atmospheric simulation model forecasts by about 6 hours (from about 5 days to about 5 days and 6 hours).

Fires in Greece as seen by A …
Title Fires in Greece as seen by Aqua/AIRS
Abstract A series of fires across Greece in August of 2007 burned 469,000 acres and claimed the lives of 65 people. The fires, in which an estimated 4,000 people lost their homes, mostly occurred in the southern part of of the country. In this visualization, the carbon monoxide signature from the fires in Greece is revealed in data retrieved by the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua spacecraft. Forest fires create large amounts of carbon monoxide. AIRS provides daily global maps of carbon monoxide from space, allowing scientists to follow the global transport of this gas day-to-day. This visualization shows the amount of Carbon monoxide that has risen 2 to 8 kilometers (6,500 ft to 26,200 ft altitude) from August 24-28, 2007. More carbon monoxide generally means more pollution, either natural from wildfires or from industrial and domestic sources. Beginning August 24, a significant plume emanates from the extensive fires burning in Greece. This plume moves southeast across the Mediterranean Sea and over North Africa from August 24 to 28. It crosses to Africa and arcs westward over the Sahara Desert and continues to curl around over the Eastern Mediterranean toward Sardinia and Corsica.

Hurricane Celia
Title Hurricane Celia
Description The image above shows Tropical Storm Celia on July 21, 2004, in visible light, as you would perceive it from space. Located in the eastern north Pacific Ocean off the coast of Mexico, Celia has a small eye with an 80-90 percent closed eyewall. Celia briefly reached hurricane status on July 22 when sustained winds reached 75 miles per hour and gusts reached 92 mph, making it the first hurricane of the eastern north Pacific season. This image was acquired by the Atmospheric Infrared Sounder (AIRS). 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.

Hurricane Isabel
Title Hurricane Isabel
Description This animation, generated with data from the Atmospheric Infrared Sounder experiment on NASA's Aqua spacecraft, depicts changes in the temperature of Hurricane Isabel as the storm moved across the Atlantic Ocean. The thermal structure of the storm is visualized as three surfaces of equal temperature, or isotherms. The temperature of each isotherm is represented by its color: red is warmest at 62 degrees Fahrenheit (17 degrees Celsius), orange is the freezing level of 32 degrees Fahrenheit, or 0 degrees Celsius, and yellow represents very cold temperatures of -10 degrees Fahrenheit, or -23 degrees Celsius. The animation tracks the hurricane from September 6, 2003, when Isabel formed off the west coast of Africa, through September 18, 2003, when it made landfall on the on the east coast of the United States. AIRS made fifteen observations of the hurricane during this period. The storm maintains a coherent shape throughout most of its life. This shape features a distinct "hump" in all three isotherms, corresponding to cooling of air as it is uplifted in Isabel's thunderstorms. This hump undergoes a distinct spreading as the storm moves westward, being much wider on Sept. 17 than on Sept. 14. The storm winds were significantly more powerful on Sept. 14, but the winds were apparently concentrated over a relatively smaller area. Also seen on the final day is the beginning of the end of the storm. The hump in the -10 degrees Fahrenheit (-23 degrees Celsius) isotherm has disappeared in the last image, suggesting that Isabel's thunderstorms had begun to weaken as the hurricane dissipated over land.

Eruption of Soufriere Hills …
Title Eruption of Soufriere Hills Volcano
Description In the early morning hours of May 20, 2006, the eruption at the Soufriere Hills Volcano on Montserrat Island in the Caribbean escalated from intermittent ash plumes to an explosive eruption as the volcano's collapsing lava dome shed about 90 million cubic meters of rock in less than three hours, reported the Montserrat Volcano Observatory. Avalanches of ash, mud, and rock mingled with heavy rain and rushed down river valleys into the ocean. The eruption also sent a cloud of ash and volcanic gas nearly 17 kilometers (55,000 feet) into the atmosphere. Flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, the Atmospheric Infrared Sounder (AIRS) tracked the cloud as it drifted west over the Caribbean Sea and Central America. Among the gases mixed in the ash cloud was sulfur dioxide, one of the gases that AIRS detects as it measures the composition of the atmosphere. AIRS measured high levels of sulfur dioxide west of the volcano as the sensor passed over the region during three consecutive overpasses on May 21, May 22, and May 23. In this image, the highest concentrations of sulfur dioxide are red, while the lowest concentrations are pale purple. (The scale is logarithmic, in which the numbers represent an exponential increase in concentration. On this scale, the exponential increase makes the sulfur dioxide concentrations at the top end of this scale not just 4.5 times bigger than the concentration at the low end, but more than 33 times bigger.) Though the gas slowly dissipated between measurements, the center of the cloud still contained a high concentration of sulfur dioxide on May 23. Aside from irritating the eyes and nose, making breathing difficult, and having a strong smell, sulfur dioxide can impact climate. Once in the atmosphere, chemical reactions (oxidation) turn sulfur dioxide into sulfate aerosol particles that create a bright haze that reflects sunlight back into space. Since less sunlight reaches the Earth, the sulfate aerosols have a cooling effect on the climate. The effect is typically regional, but if enough of the gas reaches high into the stratosphere, the part of the atmosphere that is 20 to 50 kilometers above the surface of the Earth, temperatures around the world can drop. AIRS was built to help scientists gain a better understanding of weather and climate, including how gases like sulfur dioxide and the aerosols they produce impact temperatures and weather patterns. The instrument measures air temperature, humidity, clouds, surface temperature, and atmospheric composition—all components of the atmosphere that influence weather and climate.

Original Caption Released with Image Figure 1: click on image for larger AIRS microwave image At 1:30 a.m. local time this morning, the remnants of (now Tropical Depression) Katrina were centered on the Mississippi-Tennessee border. This microwave image from the Atmospheric Infrared Sounder instrument on NASA's Aqua spacecrat shows that the area of most intense precipitation was concentrated to the north of the center of activity. The infrared image shows how the storms look through an AIRS Infrared window channel. Window channels measure the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures are associated with high, cold cloud tops that make up the top of the hurricane. The infrared signal does not penetrate through clouds, so the purple color indicates the cool cloud tops of the storm. In cloud-free areas, the infrared signal is retrieved at the Earth's surface, revealing warmer temperatures. Cooler areas are pushing to purple and warmer areas are pushing to red. The microwave image (figure 1) reveals where the heaviest precipitation in the hurricane is taking place. The blue areas within the storm show the location of this heavy precipitation. Blue areas outside of the storm where there are moderate or no clouds are where the cold (in the microwave sense) sea surface shines through.

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., This image shows Hurricane Frances as captured by instruments onboard two different satellites: the AIRS infrared instrument onboard Aqua, and the SeaWinds scatterometer onboard QuikSCAT. Both are JPL-managed instruments. AIRS data are used to create global three-dimensional maps of temperature, humidity and clouds, while scatterometers measure surface wind speed and direction over the ocean. The red vectors in the image show Frances' surface winds as measured by SeaWinds on QuikSCAT. The background colors show the temperature of clouds and surface as viewed in the infrared by AIRS, with cooler areas pushing to purple and warmer areas are pushing to red. The color scale on the right gives the temperatures in degrees Kelvin. (The top of the scale, 320 degrees Kelvin, corresponds to 117 degrees Fahrenheit, and the bottom, 180 degrees K is -135 degrees F.) The powerful circulation of this storm is evident from the combined data as well as the development of a clearly-defined central "eye". The infrared signal does not penetrate through clouds, so the light blue areas reveal the cold clouds tops associated with strong thunderstorms embedded within the storm. In cloud-free areas the infrared signal comes from Earth's surface, revealing warmer temperatures. The power of the SeaWinds scatterometer data set lies in its ability to generate global maps of wind speed and direction, giving us a snapshot of how the atmosphere is circulating. Weather prediction centers, including the Tropical Prediction Center - a branch of NOAA that monitors the creation of ocean-born storms, use scatterometer data to help it "see" where these storms are brewing so that warnings can be issued and the storms, with often erratic motions, can be tracked. While the SeaWinds instrument isn't designed to gather hurricane data, having difficulty seeing the surface in heavy rain, it's data can be used in combination with other data sets to give us an insight into these storms. In this combination image, the AIRS infrared data reveals the temperature of the atmosphere around the storm, but doesn't tell us about the wind direction or relative intensity. The directional vectors of the SeaWinds data set show how the air is circulating around the storm. Scatterometers measure surface wind speed and direction by bouncing microwave pulses off the ocean's surface. The SeaWinds instruments measure the backscattered radar energy from wind-generated ocean waves. By making multiple measurements from different looks at the same location, we can infer the vector wind averaged over each 25 km resolution cell. The primary mission objective of the SeaWinds and QuikSCAT scatterometers is to obtain long-term, global coverage of the ocean vector winds for oceanographic and climate research. While not specifically designed for detailed mapping and tracking of hurricanes, both instruments have been found to be useful resources for operational forecasters. The Atmospheric Infrared Sounder

Title Tropical Storm Bonnie as Observed by NASA's Spaceborne Atmospheric Infrared Sounder (AIRS)
Original Caption Released with Image This image of tropical storm Bonnie was captured on August 11 at 1:30am CDT. Located in the Gulf of Mexico, the center of the storm is positioned about 280 miles south-southwest of the mouth of the Mississippi River. Bonnie is a small tropical storm with wind speeds sustained at 45 mph and extending 30 miles from the storm center. It is moving northward at 5 mph. About the Movies The major contribution to radiation (infrared light) that AIRS infrared channels sense comes from different levels in the atmosphere, depending upon the channel wavelength. To create the movies, a set of AIRS infrared channels were selected which probe the atmosphere at progressively deeper levels. If there were no clouds, the color in each frame would be nearly uniform until the Earth's surface is encountered. The tropospheric air temperature warms at a rate of 6 K (about 11 F) for each kilometer of descent toward the surface. Thus the colors would gradually change from cold to warm as the movie progresses. Clouds block the infrared radiation. Thus wherever there are clouds we can penetrate no deeper in infrared. The color remains fixed as the movie progresses, for that area of the image is "stuck" to the cloud top temperature. The coldest temperatures around 220 K (about -65 F) come from altitudes of about 10 miles. We therefore see in a 'surface channel' at the end of the movie, signals from clouds as cold as 220 K and from Earth's surface at 310 K (about 100 F). The very coldest clouds are seen in deep convection thunderstorms over land. Images August 11, 2004 Infrared image. August 10, 2004 Daylight snapshot from AIRS visible/near-infrared sensor.

Original Caption Released with Image Microwave Image These infrared, microwave, and visible images were created with data retrieved by the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite. Infrared Image Because infrared radiation does not penetrate through clouds, AIRS infrared images show either the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the storm. In cloud-free areas the AIRS instrument will receive the infrared radiation from the surface of the Earth, resulting in the warmest temperatures (orange/red). Microwave Image In the AIRS microwave imagery, deep blue areas in storms show where the most precipitation occurs, or where ice crystals are present in the convective cloud tops. Outside of these storm regions, deep blue areas may also occur over the sea surface due to its low radiation emissivity. On the other hand, land appears much warmer due to its high radiation emissivity. Microwave radiation from Earth's surface and lower atmosphere penetrates most clouds to a greater or lesser extent depending upon their water vapor, liquid water and ice content. Precipitation, and ice crystals found at the cloud tops where strong convection is taking place, act as barriers to microwave radiation. Because of this barrier effect, the AIRS microwave sensor detects only the radiation arising at or above their location in the atmospheric column. Where these barriers are not present, the microwave sensor detects radiation arising throughout the air column and down to the surface. Liquid surfaces (oceans, lakes and rivers) have "low emissivity" (the signal isn't as strong) and their radiation brightness temperature is therefore low. Thus the ocean also appears "low temperature" in the AIRS microwave images and is assigned the color blue. Therefore deep blue areas in storms show where the most precipitation occurs, or where ice crystals are present in the convective cloud tops.

Title Typhoon Ioke in the Western Pacific
Original Caption Released with Image These infrared, microwave, and visible images were created with data retrieved by the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite. Infrared Image Because infrared radiation does not penetrate through clouds, AIRS infrared images show either the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the storm. In cloud-free areas the AIRS instrument will receive the infrared radiation from the surface of the Earth, resulting in the warmest temperatures (orange/red). Microwave Image In the AIRS microwave imagery, deep blue areas in storms show where the most precipitation occurs, or where ice crystals are present in the convective cloud tops. Outside of these storm regions, deep blue areas may also occur over the sea surface due to its low radiation emissivity. On the other hand, land appears much warmer due to its high radiation emissivity. In the AIRS microwave imagery, deep blue areas in storms show where the most precipitation occurs, or where ice crystals are present in the convective cloud tops. Outside of these storm regions, deep blue areas may also occur over the sea surface due to its low radiation emissivity. On the other hand, land appears much warmer due to its high radiation emissivity. Microwave radiation from Earth's surface and lower atmosphere penetrates most clouds to a greater or lesser extent depending upon their water vapor, liquid water and ice content. Precipitation, and ice crystals found at the cloud tops where strong convection is taking place, act as barriers to microwave radiation. Because of this barrier effect, the AIRS microwave sensor detects only the radiation arising at or above their location in the atmospheric column. Where these barriers are not present, the microwave sensor detects radiation arising throughout the air column and down to the surface. Liquid surfaces (oceans, lakes and rivers) have "low emissivity" (the signal isn't as strong) and their radiation brightness temperature is therefore low. Thus the ocean also appears "low temperature" in the AIRS microwave images and is assigned the color blue. Therefore deep blue areas in storms show where the most precipitation occurs, or where ice crystals are present in the convective cloud tops. Outside of these storm regions, deep blue areas may also occur over the sea surface due to its low radiation emissivity. Land appears much warmer due to its high radiation emissivity.

At the time the data were taken from which these images were made, the Typhoon Saomai was nearly on-shore in China with winds of 130mph, and the storm has a well developed eye. 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.

Title Sulfur Dioxide Plume from Mt. Etna Eruption 2002 as Detected with AIRS Data
Original Caption Released with Image Mt. Etna, a volcano on the island of Sicily, erupted on October 26, 2002. Preliminary analysis of data taken by the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite on October 28 shows the instrument can provide an excellent means to study the evolution and structure of the sulfur dioxide plume emitted from volcanoes. These data also demonstrate that AIRS can be used to obtain the total mass of sulfur dioxide injected into the atmosphere during a volcanic event, information that may help us to better understand these dangerous natural occurrences in the future. The image clearly shows the sulfur dioxide plume. This image was created by comparing data taken at two different frequencies, or channels, and creating one image that highlights the differences between these two channels. Both channels are sensitive to water vapor, but one of the channels is also sensitive to sulfur dioxide. By subtracting out the common water vapor signal in both channels, the sulfur dioxide feature remains and shows up as an enhancement in the difference image.
