Formic acid above the Jungfraujoch during 1985–2007: observed variability, seasonality, but no long-term background evolution
Formic acid the Jungfraujoch 1985–2007 background evolution
2010/11/3
This paper reports on daytime total vertical column abundances of formic acid (HCOOH) above the Northern mid-latitude, high altitude Jungfraujoch station (Switzerland; 46.5° N, 8.0° E, 3580 m alt.). T...
Influence of vortex dynamics and atmospheric turbulence on the early evolution of a contrail
vortex dynamics atmospheric turbulence the early evolution of a contrail
2010/8/12
This study describes three-dimensional numerical simulations of the evolution of an aircraft contrail during the first 30 min following the emission of exhausts. The wake is modeled as a vortex pair d...

Diurnal evolution cloud base heights convective cloud fields MSG/SEVIRI
2009/3/13
This study shows that it is possible to retrieve the temporal evolution of cloud base heights in convective broken cloud fields from data of the SEVIRI instrument onboard the geostationary satellite M...
Laboratory investigation of photochemical oxidation of organic aerosol from wood fires 1: measurement and simulation of organic aerosol evolution
photochemical oxidation organic aerosol wood fires organic aerosol evolution
2009/3/13
Experiments were conducted to investigate the effects of photo-oxidation on organic aerosol (OA) emissions from flaming and smoldering hard- and soft-wood fires under plume-like conditions. This was d...
An investigation of processes controlling the evolution of the boundary layer aerosol size distribution properties at the Swedish background station Aspvreten
processes controlling boundary layer aerosol size distribution properties Swedish background station Aspvreten
2009/3/10
Aerosol size distributions have been measured at the Swedish background station Aspvreten (58.8° N, 17.4° E). Different states of the aerosol were determined using a novel application of cluster analy...

Evolution of organic inorganic components of aerosol Saharan dust episode French Alps
2009/3/10
A Saharan dust event was observed in a rural area in the Maurienne Valley (French Alps) in summer 2000. Detailed data on PM10, particle numbers, and aerosol chemistry (ionic species and Elemental Carb...
Columnar modelling of nucleation burst evolution in the convective boundary layer – first results from a feasibility study Part IV: A compilation of previous observations for valuation of simulation results from a columnar modelling study
nucleation burst convective boundarylayer feasibility study
2009/1/15
In the preceding Papers I, II and III a revised columnar high-order modelling approach to model gas-aerosol-turbulence interactions in the convective boundary layer (CBL) was proposed, and simulation...
