    "abstract": "These files contain measurements of the particle number size distribution (PNSD) taken with a suite of instruments explained below, as well as gas phase sulfuric acid (H2SO4), gas phase sulfuric acid (H2SO4 dimer), and oxygenated organic molecules (OOMs) as measured by Nitrate CIMS (Chemical Ionisation Mass Spectrometer).\r\n\r\nThe data were taken at five urban site across Europe. At an urban background site in Manchester, UK (MAN_UB), one at an urban background site and one at a roadside site in Leipzig, Germany (LEJ_UB, LEJ_RS ), one at an urban background site and one at a roadside site in Barcelona, Spain (BCN_UB, BCN_RS).",

The PNSD data were collected across multiple instruments, data inversion was performed and the data were corrected for line-losses and multiple charges where appropriate. Where multiple columns were used and there were discrepanacies between the magnitudes of the size distribution in the regions with overlap (e.g., long and nanoSMPS), the nanoSMPS was corrected to the longSMPS, and the integrated counts of the resultant PNSD were compared with a CPC if available.\r\n\r\nThe LongSMPS, NanoSMPS, and CPC instruments were intercompared and calibrated at the World Calibration Centre for Aerosol Physics (WCCAP) before deployment in Leipzig, Germany.\r\n\r\nThe CIMS data were mass calibrated, background corrected, and the peak widths were established, and the peak fits were consequently performed in ToFware 3.2.5.",
