Dataset for Measurement report: New particle formation and aerosol properties at a newly founded atmospheric observatory at the Finnish Baltic Sea coast

These files contain aerosol, meteorological, and trace gas data used in the manuscript "Measurement report: New particle formation and aerosol properties at a newly founded atmospheric observatory at the Finnish Baltic Sea coast" measured at the Tvärminne zoological station in 2022-2024. The file contents are listed below. File "tzsEventClassification2023withHituV20240618.xlsx" Column 1: date Column 2: 1 if NPF event class for Tvärminne data is Class I Column 3: 1 if NPF event class for Tvärminne data is Class II Column 4: 1 if NPF event class for Tvärminne data is Undefined Column 5: 1 if NPF event class for Tvärminne data is Non-event Column 6: 1 if size distribution data for this date in Tvärminne was not usable Column 7: 1 if NPF event class for Hyytiälä data is Class I Column 8: 1 if NPF event class for Hyytiälä data is Class II Column 9: 1 if NPF event class for Hyytiälä data is Undefined Column 10: 1 if NPF event class for Hyytiälä data is Non-event Column 11: 1 if size distribution data for this date in Hyytiälä was not usable Column 12: 1 if event at both sites simlutaneously File 'tvarminneData20250801.xlsx' contains time series data for different variables used in the boz plots and correlation analysis of the manuscript. Column: Columns 1 to 5: year, month, day, hour, minute Column 6: number concentration of negative sub-2 nm ions (cm^-3) Column 7: number concentration of negative 2-2.3 nm ions (cm^-3) Column 8: number concentration of negative 2-7 nm ions (cm^-3) Column 9: number concentration of negative 7-25 nm ions (cm^-3) Column 10: number concentration of 10-25 nm particles (cm^-3) Column 11: number concentration of 25-100 nm particles (cm^-3) Column 12: number concentration of 100-1000 nm particles (cm^-3) Column 13: number concentration of 1000-20 000 nm particles (cm^-3) Column 14: Condensation sink (s^-1) Column 15: Wind speed (m/s) Column 16: Wind direction (degrees) Column 17: Ambient temperature (K) Column 18: Total incident radiation (W m^-2) Column 19: Relative humidity (%) Column 20: Carbon monoxide (ppb) Column 20: Ozone (ppb) Column 20: Sulfur dioxide (ppb) Column 20: Nitrogen oxide (ppb) Column 20: Nitrogen dioxide (ppb) File: 'tvarminneSizeDistributionData20250713.xlsx' contains size distribution data that was used for the calculation of condensation sink and particle number concentrations in different size ranges. The first five columns contain the time (year, month, day, hour, minute) and the rest of the columns starting from the seventh column indicate the particle concentration in dN/dlog dp in size bin indicated by the first row.
