New Data from Aura's Microwave Limb Sounder (MLS) Nitric Acid |
| Abstract |
The Microwave Limb Sounder (MLS) measures the chemistry of the lower stratosphere and upper troposphere. Nitric Acid is a corrosive, non-volatile, and inorganic acid. In the atmosphere it is formed by the conversion of nitrogen monoxide into nitrogen dioxide, and ultimately into nitric acid. |

New Data from Aura's Microwave Limb Sounder (MLS) Ozone |
| Abstract |
The Microwave Limb Sounder (MLS) measures the chemistry of the lower stratosphere and upper troposphere. Ozone that is present in the troposphere is mostly a result of anthropogenic pollution and therefore higher concentrations are found in urban areas. |

New Data from Aura's Microwave Limb Sounder (MLS) Hydrochloric Acid |
| Abstract |
The Microwave Limb Sounder (MLS) measures the chemistry of the lower stratosphere and upper troposphere. Hydrogen Chloride, is a covalent bonded nonflammable gas and ionizes almost completely when dissolved in water. When dissolved in water, hydrogen chloride forms a strong acid, hydrochloric acid. |

New Data from Aura's Microwave Limb Sounder (MLS) Water Vapor |
| Abstract |
The Microwave Limb Sounder (MLS) measures the chemistry of the lower stratosphere and upper troposphere. Measuring concentration of water vapor and other chemicals. Approximately 50 percent of the atmosphere's moisture lies within about 1.84 km of the earth's surface, and only a minute fraction of the total occurs above the tropopause. |

New Data from Aura's Microwave Limb Sounder (MLS) Chlorine Monoxide |
| Abstract |
The Microwave Limb Sounder (MLS) measures the chemistry of the lower stratosphere and upper troposphere. Measuring concentration of chlorine monoxide and other chemicals. Chlorine monoxide (CIO) is formed by the photolysis of CFCs in the stratosphere and the subsequent destruction of an ozone molecule, these radicals can act as a catalyst in the destruction of ozone while not being destroyed themselves. |

Dust blowing off West Africa
| Title |
Dust blowing off West Africa |
| Description |
This true-color image shows a large cloud of Saharan Desert dust (tan pixels) blowing westward over Niger, Mali, and Mauritania in northwestern Africa. The dust can also be seen extending westward over the Atlantic ocean in this scene. The bright feature in the eastern Atlantic (image bottom center) is sunglint, caused when the Sun's rays are reflected off the surface of the ocean directly back at the satellite. This image was acquired on October 11, 2004, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite. The high-resolution copy available here is 250 meters per pixel. NASA image by Jesse Allen, Earth Observatory, using data courtesy the MODIS Rapid Response team at Goddard Space Flight Center |

Mount St. Helens
| Title |
Mount St. Helens |
| Description |
Believe it or not, Mount St. Helens was an erupting volcano when the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER [ http://asterweb.jpl.nasa.gov/ ]) acquired this image on December 12, 2005. It may not be spouting ash and steam, but Mount St. Helens is steadily pushing a column of rock into its crater. Throughout 2005, the dome in the volcano's crater grew by an average of two cubic meters per second as magma pushed its way steadily up. In this image, snow and shadow mask the growing dome, which is on the southeast side of the crater. There are several types of volcanic eruptions [ http://pubs.usgs.gov/gip/volc/eruptions.html ] ranging from violent explosions to oozing lava, and Mount St. Helens has demonstrated many of them. In 1980, the volcano erupted violently, sending up a cloud of ash and volcanic gas and blasting pyroclastic flows—fast-moving clouds of rock fragments, ash, and gases—down the mountain. The most recent eruption [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12489 ] started with a swarm of earthquakes on September 23, 2004. By October 1, the volcano has breathed out a plume of ash and steam, and then settled into its dome-building eruption on October 11, 2004. Fourteen months later, the dome-building eruption continued, punctuated by small earthquakes that shake the mountain every minute and a half as magma rises in the dome. Mount St. Helens is the youngest and most frequently active of all of the volcanoes in the Cascade Range of the northwestern United States. The Cascades Volcano Observatory [ http://vulcan.wr.usgs.gov/Volcanoes/MSH/framework.html ] provides daily updates and photos of the eruption.

Fires in Northern Australia
| Title |
Fires in Northern Australia |
| Description |
Several large fires and many scattered smaller ones were burning in Northern Territory, Australia, on October 11, 2004. This image of the fires (actively burning areas marked in red) shows the area imaged by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite. Large-scale fires (dark brown terrain shows what has burned) are not uncommon for the tropical savannas and woodlands of northern Australia for this time of year, at the transition from dry to wet season. Sometimes the fires occur naturally through lightning strikes, and sometimes they are intentional, land management burns. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team. |

Fires on Borneo and Sumatra
| Title |
Fires on Borneo and Sumatra |
| Description |
Since mid-August, fires have been burning off and on in southern Borneo, and a blanket of smoke has been drawn over the island. Most of the island is occupied by the Kalimantan region of Indonesia, with the southern coastal areas originally home to lowland rainforests, peat swamp forests, and wetland areas. Degradation of these landscapes through unregulated and illegal logging, as well as intentional and accidental fire is a severe environmental and social problem for the country. In this image captured on October 11, 2004, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite, thick smoke nearly hides the southern part of the island, and active fires detected by MODIS are marked in red. NASA image created by Jesse Allen, Earth Observatory, using data provided by the MODIS Rapid Response team. |

Fires on Cape York Peninsula and New Guinea |
| Description |
Across the lowlands of southern New Guinea, numerous fires (marked in red) were burning on October 11, 2004, when this image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite. The island is occupied by two different nations: the western (left) half by the Indonesian territory of Irian Jaya and the eastern (right) half by Papua New Guinea. The image is roughly centered on the boundary between the two, and fires are burning across both countries. Both countries are struggling to control illegal logging. The Website of the Food and Agriculture Organization [ http://www.fao.org/forestry/foris/webview/forestry2/index.jsp?siteId=5081&sitetreeId=18927&langId=1&geoId=0 ] of the United Nations reports that some estimates suggest that 40 to 60 percent of the industrial roundwood in Indonesia is not legally harvested. In Papua New Guinea, logging continues, despite an official ban on logging exports, according to information from the U.S. State Department. [ http://www.state.gov/r/pa/ei/bgn/2797.htm ] Whether these particular fires are related to illegal logging is unknown, but often fire is used by timber operators and tree plantation owners to degrade undisturbed rainforest in the hopes of gaining concessions to the land.
