MLS Looking at the Limb
| Title |
MLS Looking at the Limb |
| Abstract |
The chemistry of ozone destruction involves very small quantities of stratospheric gases which change rapidly with altitude. UARS is able to determine the altitude variation of these gases by looking at the atmosphere edge on. This is called limb sounding. The Microwave Limb Sounder (MLS) measures microwave emission from ozone and chlorine monoxide, a major ozone destroying radical. |

| Full Description |
Designed by the astronaut crewmembers, the STS 48 patch represents the Space Shuttle Orbiter Discovery in orbit about the Earth after deploying the Upper Atmospheric Research Satellite (UARS) depicted in block letter style. The stars are those in the Northern Hemisphere as seen in the fall and winter when UARS will begin its study of Earth's atmosphere. The color bands on Earth's horizon, extending up to the UARS spacecraft, depict the study of Earth's atmosphere. The triangular shape represents the relationship among the three atmospheric processes that determine upper atmospheric structure and behavior: chemistry, dynamics and energy. In the words of the crewmembers, This continuous process brings life to our planet and makes our planet unique in the solar system.? |

Eruption of Anatahan
| Title |
Eruption of Anatahan |
| Description |
Explosive volcanic eruptions inject gases and ash into the Earth?s atmosphere, creating hazardous conditions for passing aircraft and the potential for climate effects. By the end of April 2005, two largest explosive eruptions had occurred at Manam (Papua New Guinea) on January 27-28, 2005, and at Anatahan (Mariana Islands) on April 5-6, 2005. These eruptions were of similar magnitude and both occurred on small islands causing major damage and evacuations on Manam island (which is inhabited) and concern over ashfall on islands south of Anatahan (which is uninhabited), respectively. The above image of Anatahan shows sulfur dioxide concentrations in the atmosphere on April 7, 2005, over 30 hours after the eruption. Sulfur dioxide (SO2) emissions from the eruption were measured by the Ozone Monitoring Instrument (OMI) on NASA?s EOS/Aura satellite. OMI detects the total column amount of SO2 between the sensor and the Earth?s surface and maps this quantity as it orbits the planet. A new perspective on the vertical distribution of the SO2 is revealed by combining the OMI data with coincident measurements made by the Microwave Limb Sounder (MLS), also part of the Aura mission. The MLS data crisscross the OMI image and clearly show that some, but not all, of the SO2 measured by OMI east of the volcano was in the upper troposphere or above. At these altitudes, sulfur dioxide?and the sulfate aerosols that form from it?can stay in the atmosphere and affect the climate for a longer period of time. A weaker SO2 signal was also measured in the same region during the nighttime MLS overpass, which crosses the image from upper right to lower left. The daytime data, running from upper left to lower right, coincide with the OMI measurements. The MLS data west of Anatahan show no significant SO2 signal, indicating that the SO2 measured by OMI in this region was in the lower troposphere. MLS measures thermal emissions from the Earth?s limb, so unlike the OMI sensor it also collects data at night. It is designed to measure vertical profiles of atmospheric gases that are important for studying the Earth?s ozone layer, climate, and air quality, such as SO2. These images, derived from preliminary, unvalidated OMI and MLS data, show MLS SO2 columns (filled circles) measured every 165 km along the Aura orbit, plotted over the OMI SO2 map. The MLS SO2 columns shown here are derived from profile measurements made from the upper troposphere into the stratosphere (~215 ? 0 hPa or ~12 km altitude and above), and the circles do not represent the actual size of the MLS footprint, which is roughly 165 kilometers by 6 kilometers. The Manam image, from January 28, 2005, shows larger SO2 amounts measured by MLS and OMI, though these data were collected only approximately 14 hours after the eruption on January 27-28. For both eruptions, peak SO2 amounts were measured by MLS at or just above the likely tropopause altitude, at the lowermost boundary of the stratosphere. Sulfate particles (aerosols) that form from sulfur gases in the stratosphere have a cooling effect on the Earth?s surface. The principal source of sulfate particles is large explosive volcanic eruptions, and the remaining sulfates in the atmosphere are believed to come from carbonyl sulfide, a gas emitted from marshes, soils, forests, and some industrial processes. Recent studies suggest, however, that there must be some other source of sulfates in the stratosphere, carbonyl sulfide concentrations are too small to account for observed sulfates. Could smaller, but more frequent volcanic eruptions, such as those at Anatahan and Manam, be contributing to this "excess" background sulfate aerosol? OMI offers much improved spatial resolution and sensitivity to SO2 compared to its predecessor, the Total Ozone Mapping Spectrometer (TOMS), and Aura's MLS is a major technological advance over the older MLS flown on the Upper Atmosphere Research Satellite (UARS) since 1991. The Aura mission will therefore allow scientists to investigate the source of sulfate aerosols in far greater detail. The OMI instrument is a Dutch-Finnish Instrument, provided to the EOS/Aura mission by The Netherlands and Finland. NIVR (the Dutch space agency) is the overall program manager, in coordination with FMI (the Finnish Meteorological Institute). The Royal Netherlands Meteorological Institute (KNMI) is the Principal Investigator institute.

Microwave Limb Sounder/El Niño Watch - February thru December, 1997 |
| Original Caption Released with Image |
This series of six images shows the movement of atmospheric water vapor over the Pacific Ocean during the formation of the 1997 El Niño condition. Higher than normal ocean water temperatures increase the rate of evaporation and the resulting warm moist air rises into the atmosphere altering global weather patterns. Data obtained by the Microwave Limb Sounder (MLS) on NASA's Upper Atmosphere Research Satellite (UARS), from late February 1997 to late December 1997, show the movement from the western Pacific to the eastern Pacific of high levels of water vapor (red) at 10 kilometers (6 miles) above the surface. Areas of unusually drier air (blue) appear over Indonesia. December 1997 data also show a rapid increase of water vapor off the coast of South America, the result of very high water temperatures in that region. |

Microwave Limb Sounder/El Niño Watch - December, 1997 |
| Original Caption Released with Image |
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. The measurements were taken by the Microwave Limb Sounder (MLS) instrument aboard NASA's Upper Atmosphere Research Satellite (UARS). These data, collected in late December 1997, show higher than normal levels of water vapor (red) over the central and eastern Pacific which indicates the presence of an El Niño condition. At the same time, the western Pacific (blue) is much drier than normal. The unusually moist air above the central and eastern Pacific is a consequence of the much warmer-than-normal ocean waters which occur during El Niño. Warmer water evaporates at a higher rate and the resulting warm moist air rises and forms tall cloud towers. In the tropics, the warm water and the resulting tall cloud towers typically produce large amounts of rain. These data show significant increases in the amount of atmospheric moisture off the coast of Peru and Ecuador since measurements were made in November 1997. The maximum water temperature in the eastern tropical Pacific, as measured by the National Oceanic and Atmospheric Administration (NOAA), is still higher than normal and these high ocean temperatures are likely responsible for an increase in evaporation and the subsequent rise in humidity. |

his series of six images shows the evolution of atmospheric water vapor over the Pacific Ocean during the 1998 El Niño condition. Higher than normal ocean water temperatures increase the rate of evaporation, and the resulting warm moist air rises into the atmosphere, altering global weather patterns. Data obtained by the Microwave Limb Sounder (MLS) on NASA's Upper Atmosphere Research Satellite (UARS) during January and February 1998 show a decrease in the extent of high levels of water vapor (red) over the eastern equatorial Pacific and an increase in water vapor (yellow to red) over the northwestern Pacific off the coast of Japan. This area is a breeding ground for winter storms that move eastward toward North America. 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.

| Original Caption Released with Image |
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. |

| Description |
Grappled by the remote manipulator system (RMS) end effector, the Upper Atmosphere Research Satellite (UARS) undergoes STS-48 pre-deployment checkout above the payload bay (PLB) of the earth-orbiting Discovery, Orbiter Vehicle (OV) 103. The UARS solar array unfolds below the RMS end effector and the Cryogenic Limb Array Etalon Spectrometer (CLAES) appears above it. An outrigger truss (far right), the Particle Environment Monitor (PEM) Zenith Energetic Particle System (ZEPS) (to left of truss), and PEM Nadir Energetic Particle System (NEPS) magnetometer (lower right) are visible. This view was taken using an electronic still camera (ESC) as part of Development Test Objective (DTO) 648, Electronic Still Photography. The digital image was stored on a removable hard disk or small optical disk, and could be converted to a format suitable for downlink transmission. |

STS-48 ESC closeup of extended UARS solar array (SA) during pre-deploy check |
| Description |
The leading edge of the Upper Atmosphere Research Satellite (UARS) solar array (SA), fully deployed, is recorded by the electronic still camera (ESC). UARS, grappled by the remote manipulator system (RMS) end effector (out of frame), is undergoing STS-48 pre-deployment checkout above the payload bay (PLB) of the earth-orbiting Discovery, Orbiter Vehicle (OV) 103. A hinge and the pyrotechnic bolts that enable the SA to deploy can be seen in this crisp image. This view demonstrates the capabilities of the ESC to provide high resolution views of hardware for review by ground controllers. This ESC image was documented as part of Development Test Objective (DTO) 648, Electronic Still Photography. The digital image was stored on a removable hard disk or small optical disk, and could be converted to a format suitable for downlink transmission. |
