The composition of nucleation and aitken modes particles during coastal nucleation events: evidence for marine secondary organic contribution
(Copernicus GmbH, 2006-10-12)
Newly-formed nanometer-sized particles have been observed at coastal and marine environments world wide. Organic species have so far not been detected in those newly-formed nucleation mode particles. In this study, we ...
Modelling the formation of organic particles in the atmosphere
(Copernicus GmbH, 2004-07-06)
Particle formation resulting from activation of inorganic stable clusters by a supersaturated organic vapour was investigated using a numerical model. The applied aerosol dynamic model included a detailed description of ...
General overview: european integrated project on aerosol cloud climate and air quality interactions (eucaari) – integrating aerosol research from nano to global scales
(Copernicus GmbH, 2011-12-21)
In this paper we describe and summarize the main achievements of the European Aerosol Cloud Climate and Air Quality Interactions project (EUCAARI). EUCAARI started on 1 January 2007 and ended on 31 December 2010 leaving a ...
Organic aerosol components derived from 25 ams data sets across europe using a consistent me-2 based source apportionment approach
(Copernicus GmbH, 2014-06-23)
Organic aerosols (OA) represent one of the major constituents of submicron particulate matter (PM1) and comprise a huge variety of compounds emitted by different sources. Three intensive measurement field campaigns to ...
The effect of physical and chemical aerosol properties on warm cloud droplet activation
(Copernicus GmbH, 2006-07-05)
The effects of atmospheric aerosol on climate forcing may be very substantial but are quantified poorly at present; in particular, the effects of aerosols on cloud radiative properties, or the "indirect effects" ...
Eucaari ion spectrometer measurements at 12 european sites – analysis of new particle formation events
(Copernicus GmbH, 2010-08-25)
We present comprehensive results on continuous atmospheric cluster and particle measurements in the size range similar to 1-42 nm within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions ...
Hygroscopic and chemical characterisation of po valley aerosol
(Copernicus GmbH, 2014-02-12)
Continental summer-time aerosol in the Italian Po Valley was characterised in terms of hygroscopic properties and the influence of chemical composition therein. Additionally, the ethanol affinity of particles was analysed. ...
The regional aerosol-climate model remo-ham
(Copernicus GmbH, 2012-11-01)
REMO-HAM is a new regional aerosol-climate model. It is based on the REMO regional climate model and includes most of the major aerosol processes. The structure for aerosol is similar to the global aerosol-climate model ...
Ubiquity of organic nitrates from nighttime chemistry in the european submicron aerosol
(Wiley-Blackwell, 2016-07-28)
In the atmosphere nighttime removal of volatile organic compounds is initiated to a large extent by reaction with the nitrate radical (NO3) forming organic nitrates which partition between gas and particulate phase. Here ...
Explaining global surface aerosol number concentrations in terms of primary emissions and particle formation
(Copernicus GmbH, 2010-05-26)
We synthesised observations of total particle number (CN) concentration from 36 sites around the world. We found that annual mean CN concentrations are typically 300-2000 cm(-3) in the marine boundary layer and free ...
