The Dataset's Variables and Attributes

Row Type	Variable Name	Attribute Name	Data Type	Value
attribute	NC_GLOBAL	cdm_data_type	String	Trajectory
attribute	NC_GLOBAL	cdm_trajectory_variables	String	trajectory_id
attribute	NC_GLOBAL	comment	String	Particle number size distributions from 0.02 to 0.6 um were measured with a TSI 3071 Differential Mobility Analyzer (DMA) (Quinn et al., 1998b) with the number concentration in each bin measured with a TSI 3760 CPC. The resulting number mobility distributions were inverted to a number size distribution by using the manufacturer-provided algorithm (Keady et al., 1983) and assuming that a Fuchs-Boltzman equilibrium charge distribution resulted from a Kr85 charge neutralizer (TSI model 3077) on the inlet of the DMA. The number concentration was corrected for the counting efficiency of the CPC (Zang et al., 1991) and diffusion losses in the DMA (Reineking et al., 1986). The sample air passed through a diffusion drier to reduce the RH to less than 25%.
