We have two particle size distribution data sets available for plotting and/or downloading.

1. A "wet" (RH=55%) DMPS measured particle number size distributions in the diameter range of 0.003 to 0.57 microns during Nauru99.
   ( File: NAURU99_nsd_dmps_wet.csv )

2. A "wet" APS measured particle number size distribution in the aerodynamic diameter range of 0.54 to 10 microns during Nauru99. (Here aerodynamic diameter means that the particle has the aerodynamic drag force equivalent to a unit density particle of that diameter.)

The following files are available for downloading. Please note: one data file may cover more than one time period, thus,some files may be listed more than once. All files are in csv (comma separated value) format. After several lines of general information each file starts with a first row that contains the particle diameter in microns for that column. The first column contains the date/time in Day-of-Year, DOY. DOY 32.5 is 1200 noon UTC on 1-February. All data are in units of dN/dlog10(Dp), N/cm^3. Missing data are designated by a -99 or a -999.
