Vertical sensitivityPAN has sensitivity between approximately 800 hPa and the tropopause. Only a vertically integrated quantity should be used, as values at individual pressures do not contain independent information.
Data qualityThe data have undergone a pre-quality check, which involves checks for retrieval convergence. 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 PAN below the clouds.
UncertaintyUncertainties on vertically-averaged PAN values between 825.4 and 215.4 hPa are estimated at 0.17 ppb for a single sounding.
Validation StageStage 2 according to NASA guidelines
Retrieval Levels16 levels: from surface to top-of-atmosphere
