This viewgraph presentation describes the scientific challenges along with the chemical and dynamic processes that govern tropospheric ozone. The contents include: 1) The challenge and why; 2) The how to do 'it'; 3) Did 'it' work; 4) What we are trying to do with 'it'; 5) What else is happening; and 6) What next.

This Algorithm Theoretical Basis Document (ATBD)describes the algorithms used to retrieve all Tropospheric Emission Sprectometer (TES) Standard Data Products.
TES V5 CH4 captures latitudinal gradients, regional variability and interannual variation in the free troposphere. V5 joint retrievals offer improved sensitivity to lower troposphere. Time series extends from 2004 to present. V5 reprocessing in progress. Upper tropospheric bias. Mitigated by N2O correction. Appears largely spatially uniform, so can be corrected. How to relate free-tropospheric values to surface emissions.
Many of the chemicals involved in the formation and destruction of tropospheric ozone are quite short-lived (seconds to a few months).
This slide presentation is a programmatic overview covering some of the highlights of the mission and serve as an introduction to the accompanying presentations at the workshop. It reviews the goals and the products of the TES experiment, a simplified chemistry of ozone in both the stratosphere and troposphere, a description of the instrument, and the TES operational modes. Included are graphs showing some of the results of TES analysis of the key constituents of the tropospheric chemistry and the inter-regional transport.
A descope of the EOS program now requires that all EOS platforms after AM1 be launched on DELTA-class vehicles, which results in much smaller platforms (and payloads) than previously envisaged. A major part of the TES hardware design effort has therefore been redirected towards meeting this challenge. The development of the TES concept continues on a schedule to permit flight on the EOS CHEM platform in 2002, where it is planned to be accompanied by HIRDLS and MLS.

This slide presentation reviews the use of the Troposhperic Emission Spectrometer (TES) which uses Fourier Transform Spectroscopy to conduct atmospheric science from space on board the Aura spacecraft. The topics are: the Aura mission, mission and instrumentation, the TES instrument, specifications, and the calibration of the instrument.
