10/3/96 |
| Description |
This image shows ocean surface wind speeds and directions over the Pacific Ocean on September 21, 1996, as they were measured by the NASA Scatterometer onboard Japan's Advanced Earth Observing Satellite. The background color indicates wind speed with blue being low winds, red is moderate winds, and yellow is high winds. The white arrows show the direction of the wind. The yellow- orange spiral features in the upper left near Japan are typhoons Violet and Tom. Typhoon Tom is in the open ocean. Typhoon Violet is just south of Japan. After these data were taken, Typhoon Violet struck the east coast of Japan, causing damage and deaths. Strong winter storm activity is also shown in orange in the southern hemisphere. NSCAT provides continuous measurements of ocean surface wind speeds and direction from space, which gives forecasters better information to predict the behavior of storms such as Violet and Tom. Data like these are being used by the National Weather Service, an agency of the National Oceanic and Atmospheric Administration in their global forecast models. NSCAT was launched August 16, 1996. The mission represents the first major collaboration in Earth remote sensing between the two nations. JPL developed, built and manages the NSCAT instrument for NASA's Mission to Planet Earth program. This "first look" image is still uncalibrated, but images like this will be routinely available after completion of the calibration validation phase on the project's World Wide Web site at http://www.jpl.nasa.gov/winds. ##### |

MLS/water vapor
This image shows differences
…
3/3/98
| Date |
3/3/98 |
| Description |
This image shows differences in atmospheric water vapor relative to a normal (average) year in the Earth's upper troposphere about 10 kilometers (6 miles) above the surface. These measurements were made by the Microwave Limb Sounder (MLS) instrument aboard NASA's Upper Atmosphere Research Satellite (UARS). This image, obtained on February 22, 1998, shows that high levels of atmospheric water vapor (red) continue to persist above the warm water pool, commonly referred to as El Niño, in the eastern equatorial Pacific Ocean. This image also shows high levels of atmospheric moisture above Southern California. The extent of this high moisture area along the equator has slightly decreased since late January, which corresponds to the shrinking volume of the warm water pool on the ocean's surface. During El Niño, the warmer ocean water off the coast of Peru evaporates at a higher rate, and the resulting warm moist air rises, forming tall cloud towers. In the tropics, the warm water and the resulting tall cloud towers typically produce large amounts of rain. These data show a new formation of high levels of moisture off the coast of Japan in an area that is the typical breeding ground for winter storms. Storms produced off the coast of Japan normally migrate eastward toward the western United States. During this El Niño condition, the southern tropical jet stream has shifted northward, bringing additional moisture from the tropics. When these two sources of moisture converge near California, they produce storms with higher-than-normal rainfall. |

Chikurachki Volcano
| Title |
Chikurachki Volcano |
| Description |
Off Russia's east coast, The Kuril Islands run in a southwesterly arc between the Kamchatka Peninsula and the northernmost island of Japan, Hokkaido. Located where the Pacific tectonic plate (covered by the Pacific Ocean) is being forced underneath the Eurasian tectonic plate (on which Russia, China, Japan, and Europe all sit), the twenty islands in the Kuril chain all have volcanoes in residence, 45 in all. This true-color MODIS image of the southern tip of the Kamchatka Peninsula and the northern Kuril Islands shows the region shrouded in clouds, but roughly in the center of the image, a dark brown ash plume from the Chikurachki Volcano on Paramushir Island has punctured the cloud layer and casts its gray shadow to the northwest. Chikurachki began erupting on January 25. This image was made from data acquired on February 24, 2002.

Chilean Lake Disappears
| Title |
Chilean Lake Disappears |
| Description |
In May 2007, the Chilean Forestry Corporation discovered that a lake in the Southern Patagonia Icefield in the Chilean Andes had disappeared. Chilean glaciologists had observed the 20,000-square-meter (roughly 215,000-squre-foot) lake, which was located between the tongues of the Glaciar Témpanos and Glaciar Bernardo, in March. (Glaciar is Spanish for "glacier.") Two months later, nothing remained except a 30-meter- (100-foot-) deep crater and some stranded ice that had once floated on the water's surface. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite captured the top image on June 23, 2007, showing a crater that the lake had occupied. In this image, the crater lies mostly in shadow, due to the low angle of the Sun during the Southern Hemisphere's winter. Despite the shadows, contour lines around the lake show where the ground level is lower than the surroundings. East of the drained lake, water still appears near the tongue of Glaciar Bernardo. In this image, made from a combination of visible and infrared light detected by ASTER, red indicates vegetation, and patches of red peek through the snow cover. ASTER acquired the bottom image on April 4, 2007, when the lake was still in place. In this imageacquired in the Chilean autumnboth the lake and a nearby tributary appear full, shown by the blue-tinted water. Vibrant red, lush vegetation covers the landscape. Although the sudden draining of a lake is rare, it is not unheard of. One explanation that scientists proposed was an earthquake in the region that measured 6.2 on the Richter scale. Earthquakes can open up fissures in the rock, giving water an escape route. Another explanation was more prosaic: melting. Blocks of ice dam many glacial lakes, and when the ice melts, the lake can drain away. Sometimes a lake can drain in a rapid deluge, known as a glacial lake outburst flood. After flying over the region in late June 2007, scientists from Centro de Estudios Cientificos (CECS) and the Chilean Navy concluded that the likely culprit for the lake's disappearance was such a flood. Dr. Andrés Rivera, a glaciologist from CECS, described the flow. "The lake's water flowed to the north along the western margin of Glaciar Bernardo and into a big hole, [ http://www.imaginaccion.cl/cecs.html ] where the water went down into a glacier tunnel in the direction to Bernardo Fjord," he said. Bernardo Fjord empties into the Pacific Ocean.

China Dust over the Pacific
| Title |
China Dust over the Pacific |
| Description |
Springtime winds whip across the Gobi Desert of Northern China and send dust flying east over the populated North China Plain. These regular dust storms are sometimes powerful enough to reach across the Pacific Ocean and dim skies over North America. In late April 2005, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) flying on the OrbView-2 satellite detected a large dust storm over China. Over the week that followed, SeaWiFS tracked the dust over the Pacific Ocean. SeaWiFS collects imagery as it orbits the Earth from pole to pole. The above images were created by piecing together the strips from each orbit. Each strip measures approximately 1,500 kilometers across, and black wedges show where no data were collected. In the top image, acquired on April 29 and April 30, 2005, northern Japan is entirely obscured by a thick cloud of dust, and a tan streamer of dust stretches east over the Pacific. The lower image was taken on May 4 and May 5, 2005. By this time, the dust had reached about two-thirds of the way across the Pacific, well on its way to North America. Intermediate images are provided in the links below. In both images, the sun's reflection off the surface of the ocean forms a series of bright spotssunglint just north of the Equator. SeaWiFS images courtesy the SeaWiFS Project [ http://seawifs.gsfc.nasa.gov/SEAWIFS.html ], NASA/Goddard Space Flight Center, and ORBIMAGE [ http://www.orbimage.com/ ].

In late April 2005, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) flying on the OrbView-2 satellite detected a large dust storm over China. Over the week that followed, SeaWiFS tracked the dust over the Pacific Ocean. SeaWiFS collects imagery as it orbits the Earth from pole to pole. The above images were created by piecing together the strips from each orbit. Each strip measures approximately 1,500 kilometers across, and black wedges show where no data were collected. In the top image, acquired on April 29 and April 30, 2005, northern Japan is entirely obscured by a thick cloud of dust, and a tan streamer of dust stretches east over the Pacific. The lower image was taken on May 4 and May 5, 2005. By this time, the dust had reached about two-thirds of the way across the Pacific, well on its way to North America. Intermediate images are provided in the links below. In both images, the sun's reflection off the surface of the ocean forms a series of bright spotssunglint just north of the Equator.
