Abstract


  • Column-averaged dry-air mole fraction of CO

    (XCO) measurements are obtained from two ground-based

    Fourier transform infrared (FTIR) spectrometer networks:

    the Total Carbon Column Observing Network (TCCON) and

    the Network for the Detection of Atmospheric Composition

    Change (NDACC). In this study, the differences between the

    TCCON and NDACC XCO measurements are investigated

    and discussed based on six NDACC–TCCON sites using data

    over the period 2007–2017. A direct comparison shows that

    the NDACC XCO measurements are about 5.5 % larger than

    the TCCON data at Ny-Ålesund, Bremen, and Izaña (Northern Hemisphere), and the absolute bias between the NDACC

    and TCCON data is within 2 % at Saint-Denis, Wollongong

    and Lauder (Southern Hemisphere). The hemispheric dependence of the bias is mainly attributed to their smoothing errors. The systematic smoothing error of the TCCON XCO

    data varies in the range between 0.2 % (Bremen) and 7.9 %

    (Lauder), and the random smoothing error varies in the range

    between 2.0 % and 3.6 %.
