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: yyyy.mm.dd HH:MM
HDOP: horizontal dillusion of precision, uncertainty of the GPS position
Number of particles [#/ccm]
Average particle diameter [nm]
LDSA: lung deposited surface area [um2 /cm3]
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:
