Nanoion 2010-11

The dataset includes results of a measurement campaign started at 1 April 2010 and finished at 8 November 2011. The full mobility range was logarithmically uniformly divided into 16 fractions. 10 of these fractions include the intermediate ions and 6 include the small ions. The dataset presents unique information about nanoparticles up to 7.4 nm in diameter in the atmospheric air.

The author acknowledges Kaupo Komsaare for taking care of the instrument, Sander Mirme for presenting the meteorological data, and Urmas Hõrrak for general arrangements and discussions. The dataset contains files: Ø nanoion2010_11data.pdf – information about the origin of data and structure of the data files, Ø nanoion2010_11instrument.pdf – description of the instrument SIGMA used for measuring nanoparticle mobility and size distribution, Ø nanoion2010_11hours.xls – hourly averages of nanoparticle distribution according to their mobility and size, complemented with meteorological data, Ø nanoion2010_11records.xls – five minute averages of nanoparticle distribution according to mobility and size, Ø nanoion2010_11diagrams.ppt – contour plots of nanoparticle size distribution evolution during 147 days, Ø nanoion2010_11.zip – compressed package of files for download and offline use on a personal computer.
