(a) Comparison of monthly LSR estimates from Aeolus versus LER estimates for Sahara (uncertainties are taken from the standard deviations of monthly estimates within the region of interest; LERTRO uncertainties are omitted for better visibility of the plot; they are very similar to LERGOM uncertainties). Intercomparison of mean estimates of (b) LERGOM vs LERTRO, (c) LSR Aeolus vs LERTRO. All the comparisons were performed at the 2.5° × 2.5° grid resolution for 2018.09–2019.08 in (b,c), 1 month of additional data (September 2019) was added for (a). In (a), LER estimates were taken from climatologies, which means that the same LER climatological estimates were used for September 2018 and September 2019. Note that the color bar reflects the number of occurrences plotted in the form of log-normal. Note that Aeolus June 2019 data were not used in this study (see Sect. "Filtering out attenuating features from LSR observations" for the detailed explanation).
