Constraining Global Carbon Budget Using Vertically-Integrated CO₂ Measurements


Yang, Zhonghua (2008) Constraining Global Carbon Budget Using Vertically-Integrated CO₂ Measurements. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/3XR2-7185.


I demonstrate that high precision measurements of the vertical-average dry volumn-mixing-ratio of atmospheric carbon dioxide (CO2 ) can be obtained from ground-based solar spectra. Oxygen measurements from the same spectra can be used to calibrate CO2 retrievals across different instruments, enabling a global network of column CO2 observations to be constructed. I also illustrate that this new type of data, together with aircraft profile CO2 observations, provide new constraints on global carbon fluxes.
