Abstract

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 CO ₂ columns were calibrated against integrated aircraft profiles obtained during the TWP-ICE campaign in Januaryg-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 CO ₂ 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.
