  In this proceeding we report initial studies into the big data set acquired
by the Cloud Condensation Nuclei (CCN) counter of the Basic Environmental
Observatory (BEO) Moussala over the whole 2016 year at a frequency of 1 Hz.
First, we attempt to reveal correlations between the results for CCN number
concentrations on the timescale of a whole year (2016) as averaged over 12
month periods with the meteorological parameters for the same period and with
the same time step. Then, we zoom into these data and repeat the study on the
timescale of a month for two months from 2016, January and July, with a day
time step. For the same two months we show the CCN size distributions averaged
over day periods. Finally, we arrive at our main result: typical, in terms of
maximal and minimal number concentrations, CCN size distributions for chosen
hours, one hour for each month of the year, hence 24 distributions in total.
These data show a steady pattern of peaks and valleys independent of the
concrete number concentration which moves up and down the number concentrations
(y-axis) without significant shifts along the sizes (x-axis).
