Assimilation of N2O in the Upper Atmosphere Using a Kalman Filter: N2O Mixing Ratio |
| Abstract |
This series of animations shows assimilation of N2O in the upper atmosphere using observations from the Cryogenic Limb Etalon Spectrometer (CLAES) on the Upper Atmosphere Research Satellite (UARS). Winds were provided by the Goddard EOS Data Assimilation System (GEOS-DAS). Flow is at the 850K isentropic level. N2O mixing ratio is expressed in parts per billion volume (ppbv). |

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. |

Viewing the ISAMS and CLAES Instruments on UARS |
| Abstract |
Key to understanding the chlorine chemistry in the polar stratosphere is the measurement of polar stratospheric clouds, chlorine monoxide, and the reservoir gas chlorine nitrate. Polar stratospheric clouds are seen by the Improved Stratospheric and Mesospheric Sounder, ISAMS, and chlorine nitrate has been measured by the Cryogen Limb Array Etalon Spectrometer, CLAES. Both ISAMS and CLAES make measurements by looking at infrared emission from cloud particles and trace gases. |

Chemical Model Animation of O3 Absorbing Low-energy UV |
| Abstract |
Ozone is a strong absorber of lower energy ultraviolet radiation which can kill living organisms. This radiation is absorbed by the ozone layer when it breaks the ozone bonds. An oxygen atom is released, but the atom quickly re-combines with another oxygen molecule to regenerate ozone. |

Chemical Model Animation of Chlorine Release from Reservoir Gases over Antarctica |
| Abstract |
Over the Antarctic continent, ice clouds form in the cold winter darkness. On the surface of the cloud particles, chlorine nitrate and hydrogen chloride react and release chlorine. The chlorine then reacts with ozone forming chlorine monoxide and starting the catalytic ozone destruction cycle. The massive ozone loss results in the development of the Antarctic ozone hole. |

Water Vapor Measurements from HALOE (1992-1997) |
| Abstract |
An animated graph showing HALOE measurements of the water vapor amounts in the upper stratosphere, illustrating that it takes about 5 years for CFCs to reach the upper atmosphere. Tropical water vapor changes slowly with seasonal cycles. These changes, shown here as thick bands, were found to slowly ascend. These measurements tell us how fast the CFCs and other pollutants rise into the stratosphere. |

| Title |
HALOE Measurements of HCl in the Stratosphere (1992 - 1998) |
| Abstract |
HALOE was designed to carefully monitor hydrogen fluoride and hydrogen chloride, byproducts of CFC destruction in the stratosphere. HALOE operates by observing the absorption of infrared radiation by these molecules against the rising and setting sun. When UARS was first launched, measurements by HALOE showed that CFC byproducts were still increasing in the stratosphere. But the newest HALOE measurements now show that CFC by-products are no longer increasing. UARS has shown that the stratosphere is starting to respond to the international ban on CFC manufacture. |

Tropical Winds in the Stratosphere from HRDI (1991-1996) |
| Abstract |
The High Resolution Doppler Interferometer (HRDI) measures winds in both the stratosphere and mesosphere. The tropical winds in the stratosphere undergo a slow two year variation called the quasibianunual oscillation. This oscillation controls mixing throughout the stratosphere and HRDI has given us much detail on wind changes associated with this oscillation. The animation indicates the line of zero wind speed in the zonal tropical winds, the height at which the winds change from eastward to westward. |

Chemical Model Animation of O3 Losing an Oxygen Atom to a Radical |
| Abstract |
Ozone is very reactive. It easily loses the third oxygen atom in the presence of other highly reactive compounds called radicals, which contain chlorine, hydrogen, nitrogen, or bromine. Minute quantities of these radicals can cause large decreases in ozone because they are not consumed in the reaction. This is called a catalytic cycle. |
