  <dc:description>Ultrafine Particle Dataset Collected by the OpenSense Zurich Mobile Sensor Network

This dataset contains one year (2012/04- 2013/04, ~11Mio. samples) worth of ultra-fine particle (UFP) concentration measurements collected by a mobile senor network. The sensors are mounted on top of 10 streetcars in the city of Zurich, Switzerland.


	Ultrafine particle sensor: MiniDiSC (see also: Martin Fierz et al. Design, Calibration, and Field Performance of a Miniature Diffusion Size Classifier. Aerosol Science and Technology, Volume 45, 2011.)
	GPS receiver: u-blox EVK-6p

*.csv column format:

	Time of day: HH:MM
	Latitude WGS84
	Longitude WGS84
	HDOP: horizontal dillusion of precision, uncertainty of the GPS position
	Tram ID
	Number of particles [#/ccm]
	Average particle diameter [nm]
	LDSA: lung deposited surface area [um2 /cm3]

Data quality:
The data has been post-processed by performing a periodic null-offset calibration and  filtering samples during malfunction.

The dataset has been used and is described in more detail in the following publications:
