Abstract


  • Abstract. This paper presents a validation study of SCanning

    Imaging Absorption spectroMeter for Atmospheric

    CHartographY (SCIAMACHY) carbon monoxide (CO) total

    column measurements from the Iterative Maximum Likelihood

    Method (IMLM) algorithm using ground-based spectrometer

    observations from twenty surface stations for the

    five year time period of 2003–2007.

    Overall we find a good agreement between SCIAMACHY

    and ground-based observations for both mean values as well

    as seasonal variations. For high-latitude Northern Hemisphere stations absolute

    differences between SCIAMACHY and ground-based measurements

    are close to or fall within the SCIAMACHY CO

    2 precision of 0.2×1018 molecules/cm2 (10%) indicating

    that SCIAMACHY can observe CO accurately at high

    Northern Hemisphere latitudes.

    For Northern Hemisphere mid-latitude stations the validation

    is complicated due to the vicinity of emission sources

    for almost all stations, leading to higher ground-based measurements

    compared to SCIAMACHY CO within its typical

    sampling area of 8 ×8.

    Comparisons with Northern Hemisphere mountain stations

    are hampered by elevation effects. After accounting

    for these effects, the validation provides satisfactory results
