Samples were collected with a Sigma-2 sampler (Waza et al., 2019) during the SAMUM-2 campaign (Heintzenberg, 2009; Kandler et al., 2009) 2 m above ground between 12 may 2006 and 06 June 2006. The geographical coordinates are N 30.2378° and W 5.6079°, height is approximately 680 m above sea level.Samples were subject to automated scanning electron microscopy with coupled X-ray analysis (Kandler et al., 2018). This data set contains the results of a sample re-analysis with more modern instrumentation in 2017.Note that not all daily samples could be analyzed, as some were totally overloaded during dust wind situations. This corresponds to the missing numbers and gaps in the time line.Each data file is one sample (approximately diurnal collection), an overview with meta data is given in the sample list file. Please refer to the description files for more details.
