| Zusammenfassung |
| An automated Fourier Transform Spectroscopic (FTS) solar observatory was
established in Darwin, Australia in August 2005. The laboratory is part of
the Total Carbon Column Observing Network, and measures atmospheric column
abundances of CO2 and O2 and other gases. Measured CO2
columns were calibrated against integrated aircraft profiles obtained during
the TWP-ICE campaign in January–February 2006, and show good agreement with
calibrations for a similar instrument in Park Falls, Wisconsin. A clear-sky
low airmass relative precision of 0.1% is demonstrated in the CO2
and O2 retrieved column-averaged volume mixing ratios. The 1%
negative bias in the FTS XCO2 relative to the World Meteorological
Organization (WMO) calibrated in situ scale is within the uncertainties of
the NIR spectroscopy and analysis. |
