Characterization of equivalent black carbon (ebc) at a regional backgound site in Central Europe: Variability and source identification
Mbengue, Saliou ; Šerfözö, Norbert ; Holubová Šmejkalová, Adéla ; Holoubek, Ivan
Black carbon (BC) is recognized to play an important role on adverse public health and in the Earth’s climate system (Bond et al., 2013). It is the most efficient light-absorbing aerosol species in the visible spectrum emitted as primary pollutant from a variety of combustion related sources. Although measurements of Equivalent Black Carbon (EBC) with multiple wavelength aethalometer have been used to provide insights regarding the influence of fossil fuel (traffic emissions) and wood smoke in ambient air (Sandradewi et al., 2008, Vaishya et al 2017), scarce studies have been reported in Eastern Central Europe using real-time EBC measurements.\nThis study focuses on the seasonal, diurnal and weekly trends of EBC at a regional background site in Central Europe during a 5-year measurement. Our aim is to identify the potential sources of EBC, especially the influence from fossil fuel and biomass burning.

Seasonal, weekly and diurnal variability of elemental and organic carbon at a rural background site in Central Europe, a four years of measurement
Mbengue, Saliou ; Fusek, M. ; Schwarz, Jaroslav ; Vodička, Petr ; Holubová, Adéla ; Holoubek, Ivan
Atmospheric organic (OC) and elemental (EC) carbon play an important role in\natmospheric chemistry, climate change and public health. There have been relatively\nfew studies dealing with EC and OC in rural background sites which are less influenced\nby urban and industrial emissions. Nevertheless, measurements at background areas are\nimportant for understanding the transport and transformation characteristics of\nanthropogenic air pollutants, and their effects on various aspects of regional and global\nenvironment changes. This work is one of the rare studies using a semi-continuous\nmeasurement technique to focus on long-term (4 years) measurements of EC and OC at\nregional background site in Europe. It focuses on the factors or phenomena influencing\nboth diurnal and weekly variability of EC and OC concentrations during various seasons\nat rural background area.

Highly time resolved measurement of atmospheric elemental and organic carbon at a typical background site in Central Europe.
Mbengue, Saliou ; Fusek, M. ; Schwarz, Jaroslav ; Holoubek, Ivan
Atmospheric organic (OC) and elemental (EC) carbon play an important role in atmospheric chemistry, climate change and public health. There have been relatively few studies dealing with EC and OC in rural background sites which are less influenced by urban and industrial emissions. Nevertheless, measurements at background areas are important for understanding the transport and transformation characteristics of anthropogenic air pollutants, and their effects on various aspects of regional and global environment changes. In this study, we focus on variability of EC and OC concentrations (considering various day categories and seasons) from a rural background site which is representative for Central European rural areas.\n
