      abstract     = {Observations of aerosol chemical composition in Cabauw, the
                      Netherlands, are presented for two intensive measurement
                      periods in May 2008 and March 2009. Sub-micron aerosol
                      chemical composition was measured by an Aerodyne Aerosol
                      Mass Spectrometer (AMS) and is compared to observations from
                      aerosol size distribution measurements as well as
                      composition measurements with a Monitor for AeRosol and
                      GAses (MARGA) based instrument and a Thermal-Desorption
                      Proton-Transfer-Reaction Mass-Spectrometer (TD-PTR-MS). An
                      overview of the data is presented and the data quality is
                      discussed. In May 2008 enhanced pollution was observed with
                      organics contributing $40\%$ to the PM1 mass. In contrast
                      the observed average mass loading was lower in March 2009
                      and a dominance of ammonium nitrate $(42\%)$ was observed.
                      The semi-volatile nature of ammonium nitrate is evident in
                      the diurnal cycles with maximum concentrations observed in
                      the morning hours in May 2008 and little diurnal variation
                      observed in March 2009. Size dependent composition data from
                      AMS measurements are presented and show a dominance of
                      organics in the size range below 200 nm. A higher O:C ratio
                      of the organics is observed for May 2008 than for March
                      2009. Together with the time series of individual tracer
                      ions this shows the dominance of OOA over HOA in May 2008.},
