Abstract:
This data set contains in-situ analysis of individual particles measured during HALO-(AC)³ in March/April 2022. Using the single particle aerosol mass spectrometer ALABAMA, particle size and chemical composition of single particles were analyzed onboard of the research aircraft Polar 6. The data provides time, location, particle size (if available), an integer value inlet_pos as indicator for the position of the ALABAMA inlet switch (2: CVI inlet, 4: standard aerosol inlet) as well as counts of different cluster types for each analyzed particle. The 38 clusters were determined by using a fuzzy-c-means algorithm, a method for grouping data points with similar signal pattern. The key chemical species of each cluster are given in the longname version of the cluster variables in the data files. A detailed description of the data processing will be done in an upcoming data paper.

Comment:
For RF04, no ALABAMA data are available due to an instrumental failure.
