Douglas Nilsson Bolin Centre Database 2022 Datafile Atmosphere Aerosols Sea spray production Salinity Temperature Surface bubble spectra Earth science > Atmosphere > Aerosols Julika Zinke 2022-06-20T14:47:49+00:00 English 3 The dataset includes six xlsx spreadsheet files: ##### Salinity experiments The file *salinity-experiments.xlsx* contains two worksheets for the two sets of salinity experiments. The size distributions, that were measured with a differential mobility particle sizer (DMPS) and optical particle size spectrometer (OPSS), were combined at 350 nm and averaged for each salinity, and are given in the form dN/dlogDp. ##### Bubble density The file *bubble-density.xlsx* provides averaged bubble densities in the field of view at each salinity. ##### Temperature ramps at distinct salinities The file *temperature-ramps.xlsx* contains four work sheets with averaged particle size distributions (in the form dN/dlogDp) for the temperature ramps at the salinities 35 g/kg , 17 g/kg and 6 g/kg (the temperature ramp at salinity 35 g/kg was repeated). The measured diameters are dry diameters and were shape corrected using a dynamic shape factor calculated according to Zieger et al. (2017). ##### Raw data The files *DMPS_data_raw.xlsx* and *OPSS_data_raw.xlsx* contain each two work sheets with the raw data over the entire periods of both sets of experiments (in the form dN/dlogDp), that were measured by the differential mobility particle sizer (DMPS) and optical particle size spectrometer (OPSS). The time frames of each experiment are given in the file *time_frames.xlsx*. Size-resolved particle concentrations were measured with a custom-built differential mobility particle sizer (DMPS) that measures particles with diameter 15 nm < Dp < 900 nm and an optical particle size spectrometer (OPSS) that measures particles 300 nm < Dp < 10 μm. These size distributions were combined at a diameter of 350 nm. Additionally, the total number concentration was measured with a condensation particle counter. The bubble size distribution at the water surface was determined photographically. #### Version history ##### Version 3 The files *salinity-experiments.xlsx* and *temperature-ramps.xlsx* have been updated. We have now loss-corrected the entire size distribution resulting from the combination of DMPS and OPSS data. ##### Version 2 The files *salinity-experiments.xlsx* and *temperature-ramps.xlsx* have been updated. The size distribution measured from the DMPS was loss-corrected for particle-sizes < 100 nm where density effects are negligible. Furthermore, we have corrected the data for an offset in the OPSS calibration between the experiments. Lastly, the size distribution of the DMPS and OPSS were combined at 350 nm instead of 500 nm to avoid multiple charging effects in the DMPS that can occur at particle sizes around 500 nm. ##### Version 1 Initial release.
