This is the metadata for: MUMBA_SMPS_2013-01-16_2013-02-18 (doi:10.1594/PANGAEA.872000)


Measurement: Particle number size distribution (~14 nm to ~660 nm)
Instrument: TSI Scanning Mobility Particle Sizer (SMPS, Model 3080) with long Differential Mobility Analyser (DMA, TSI 3071A) and CPC (TSI 3010) (64 channels) 
Owner: CSIRO
Campaign: MUMBA
Location: Main measurement site - Nissan Hut Kids Campus / Campus East, Wollongong (-34.3972, 150.8996)
Dates of operation: 16-Jan-2013 to 15-Feb-2013
Original measurement time resolution: samples for ~2.5 minutes every 5 minutes
Averaging time: 1 hour
Units: 	diameter: nm
	particle concentrations: dN/dLogDp particles cm-3 

Inlet/Installation detail: Air was sampled through an 8 m copper bypass running at a flow rate of ~15L/minute. Inlet height was ~10m. This bypass was shared between the CPC, CCNC and SMPS instruments.
Data/sample collection detail: aerosol flow was 0.30 +- 0.03 L/minute and sheath flow was 3.0 +- 0.3 L/minute 
Calibration: Sizing accuracy of the SMPS system was checked using PolyStyrene Latex (PSL) solution with errors being less than 2 % 


Issues: The instrument was shut down due to excessive heat on 18-20-Jan-2013
Corrections: 	Original timestamp of data collected from 16-Jan-2013 until 18-Jan-2013 was corrected from GMT+11 to GMT+10
		Data was corrected for inlet flow rates (20%) and inlet losses (0.9 transmission factor) and filtered for logged poor periods.

Uncertainty: +-10% (Wiedensohler et al 2012)
