| Zusammenfassung |
| The Orbiting Carbon Observatory, scheduled to launch early in 2009, will make spatially
resolved measurements of the column averaged CO2 dry air mole fraction, XCO2, with
precisions of 1 ppm to distinguish their spatial and temporal gradients of CO2. Achieving this
goal requires implementation of non-Voigt line shape models, line mixing and improved
molecular line parameters for near infrared absorption bands of O2 (near 760 nm), and CO2
(near 1600 and 2060 nm) . The first interval is dominated by the absorptions of the O2
A-band while the others contain strong CO2 features, as well as weak transitions of water and
methane. The OCO linelist is composed of results from numerous new laboratory studies
undertaken to improve experimental precisions and to characterize line mixing effects. The
sources and accuracies of the new linelist for the three OCO channels1 will be
described.
The research described in this paper was performed at the Jet Propulsion Laboratory,
California Institute of Technology, under contract with The National Aeronautics and Space
Administration. |
