Nitrogen Dioxide concentration over China from September 24, 2004, to November 7, 2004 |
| Abstract |
Nitrogen dioxide, NO2, is a traffic-related pollutant. Emmisions are generally highest in urban rather than rural areas. Annual mean concentrations of nitrogen dioxide in urban areas are generally in the range 10-45 ppb, and lower in rural areas. Levels vary significantly throughout the day, with peaks generally occurring twice daily as a consequence of rush hour traffic. Concentrations can be as high as 200 ppb. Particulate matter is very fine and can be carried deep into the lungs where they can cause inflammation and a worsening of the condition of people with heart and lung disease. Further, the problem is not necessarily concentrated in the inner cities. Because many major road / motorway interchange complexes are situated in semi-rural areas, under conditions of near-stationary traffic, a rapid build-up of engine exhaust pollution can occur, which if the low-level atmospheric conditions are correct, will not be dispersed. |

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. |
