AB: Atmospheric CO is a major precursor of tropospheric ozone and the main sink for tropospheric OH, the dominant atmospheric oxidant. Inverse modelling of measurements of CO has emerged as a powerful means for quantifying surface emissions of CO. We report results from the first inverse modelling of measurements of CO from the TES instrument, launched on the Aura satellite. Using a Bayesian synthesis inversion approach, we examine the constraints on estimates of the emissions of CO provided by TES. We conduct a global inversion analysis, with a particular focus on Asian sources of CO. We also compare the constraints offered by TES with those from the MOPITT instrument. Recently, studies have explored integrating space-based and aircraft measurements. We examine here the utility of integrating observations from the two satellite instruments in the inversion analysis. The MOPITT and TES data sets are incorporated separately and together in the inversion to quantify the consistency and complementarity of the two data sets toward quantifying the CO emissions.
