Vertical sensitivityEstimates of carbon monoxide concentrations from thermal infrared satellite observations are most sensitive to CO variability between 850 and 200 mb. However, sensitivity depends on observed scene parameters such as thermal contrast and can be variable. Users should assess individual retrieval sensitivity using the averaging kernel (AK) for CO profiles and degrees of freedom for signal (DFS) or column AK for total column CO.
Data qualityThe L2 Standard data products have undergone a pre-quality check, which involves checks for retrieval convergence and measurement sensitivity. There are no checks for clouds or land versus ocean as we do not find these to substantively affect the quality of the retrieval as long as the retrieval has converged. Note that retrievals over thick clouds will not be sensitive to CO below the clouds.
UncertaintyProfiles levels have approximately 7% observational error (does not include vertical smoothing error).
Validation StageStage 3 according to NASA guidelines
Retrieval Levels14 levels: from surface to top-of-atmosphere
