Vertical sensitivityEstimates of water vapor concentrations from thermal infrared satellite observations are most sensitive to H2O variability between 825 and 300 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 H2O profiles and degrees of freedom for signal (DOFS) or column AK for total column H2O.
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 H2O below the clouds.
UncertaintyProfiles levels have approximately 20% observational error (does not include vertical smoothing error).
Validation StageStage 4 according to NASA guidelines
Retrieval Levels17 levels: from surface to top-of-atmosphere
