Cover Story: For the example of AVHRR aerosol optical depth (AOD) retrieval, a thorough analysis of the retrieval operator and its sensitivities to the used input and auxiliary variables is undertaken to quantify the different contributions to AOD uncertainties. Uncertainties are then propagated from measured reflectances to geophysical retrieved AOD datasets at different product levels. The propagation uses uncertainty correlations of separate uncertainty contributions from the FIDUCEO easyFCDR level1b input and other major effects in the retrieval. The uncertainties are statistically validated against true error estimates versus AERONET ground-based AOD. The study demonstrates the benefits of new recipes for uncertainty characterization from the Horizon 2020 project FIDUCEO. View this paper
