A. Wiedensohler,A. Wiesner,Kay Weinhold,Wolfram Birmili,Markus Hermann,Maik Merkel,Thomas Müller,Sascha Pfeifer,A. Schmidt,Thomas Tuch,Fernando Velarde,Paul Quincey,Stefan Seeger,Andreas Nowak +13 more
TL;DR: The mobility particle size spectrometers (MPSS) belong to the essential instruments in aerosol science that determine the particle number size distribution (PNSD) in the submicrometer size range as discussed by the authors.

TL;DR: In this article, the authors provide the widest effort so far to document variability of climate-relevant in situ aerosol properties (namely wavelength dependent particle light scattering and absorption coefficients, particle number concentration and particle number size distribution) from all sites connected to the Global Atmospheric Watch network.
Journal ArticleDOI
Frequent nucleation events at the high altitude station of Chacaltaya (5240 m a.s.l.), Bolivia
Clémence Rose,Karine Sellegri,Fernando Velarde,Isabel Moreno,M. Ramonet,Kay Weinhold,Radovan Krejci,Patrick Ginot,Marcos Andrade,A. Wiedensohler,Paolo Laj +10 more
TL;DR: In this article, the authors detected and analyzed at the highest measurement site in the world, Chacaltaya (5240m a.s.l.), Bolivia between January 1 and December 31 2012, using a Neutral Aerosol and Ion Spectrometer (NAIS) that detects clusters down to 0.4nm.
Journal ArticleDOI
CCN production by new particle formation in the free troposphere
Clémence Rose,Karine Sellegri,Isabel Moreno,Fernando Velarde,Michel Ramonet,Kay Weinhold,Radovan Krejci,Marcos Andrade,Alfred Wiedensohler,Patrick Ginot,Paolo Laj +10 more
TL;DR: In this paper, the authors focused on the impact of particle formation on cloud condensation nuclei (CCN) population and evaluated the contribution of new particle formation relative to the transport and growth of pre-existing particles to CCN size.
Journal ArticleDOI

TL;DR: In this article, the authors identify and attribute the most important common data quality issues in Bolivian and Peruvian temperature and precipitation datasets, and find that a large fraction of these issues can be traced back to measurement errors by the observers.
