Description
This work reports the first statistical analysis of multi-annual data on tropospheric aerosols from the German
Ultrafine Aerosol Network (GUAN). Compared to other networks worldwide, GUAN with 17 measurement locations
has the most sites equipped with particle number size distribution (PNSD) and equivalent black carbon
(eBC) instruments and the most site categories in Germany ranging from city street/roadside to High Alpine. As
we know, the variations of eBC and particle number concentration (PNC) are influenced by several factors such
as source, transformation, transport and deposition. The dominant controlling factor for different pollutant
parameters might be varied, leading to the different spatio-temporal variations among the measured parameters.
Currently, a study of spatio-temporal variations of PNSD and eBC considering the influences of both site categories
and spatial scale is still missing. Based on the multi-site dataset of GUAN, the goal of this study is to
investigate how pollutant parameters may interfere with spatial characteristics and site categories.
