- yr : 4-digit year (UTC)
- mo : 2-digit month (UTC)
- dy : 2-digit day (UTC)
- hr : 2-digit hours (UTC)
- mn : 2-digit minutes (UTC)
- sc : 2-digit seconds (UTC)
- Pex : absolute pressure in the DMA loop (hPa)
- Tex : temperature in the DMA loop (K)
- RHsh : relative humidity in the DMA loop (%)
- TGrad : non used
- nb : number of bins (unitless)
- Dbeg : particle diameter of the first bin of the scan (nm)
- Dend : particle diameter of the last bin of the scan (nm)
- concTotal : total concentration (#/cm ^3^ )
- conc : nb columns of size concentration for each bin, dN/dLog format (#/cm ^3^ )

The diameters are logathmically distributed. As a consequence, it is not necessary to save the full diameter list since it is easy to [[Build_the_list_of_diameters]].
