TL;DR: In this paper, a regional chemistry transport model (WRF-Chem) was used to evaluate processes controlling the regional distribution of tropospheric ozone over Western Siberia for late-spring and summer in 2011.
Journal ArticleDOI
Impacts of volatilisation on light scattering and filter-based absorption measurements: a case study
TL;DR: In this paper, a short field campaign with two groups of equipment measuring in parallel for six days in April 2009 at the SMEAR III station in Helsinki was studied during a short-term experiment.
Journal ArticleDOI
Real-time detection of arsenic cations from ambient air in boreal forest and lake environments

TL;DR: In this paper, the first observation of airborne organic and inorganic arsenic cations, detected in real time within the boreal forest in Hyytiala, Finland, and over nearby Lake Kuivajarvi, was presented.
Journal ArticleDOI

TL;DR: In this article, the average charging state of aerosol populations was determined using an Ion-DMPS in Helsinki, Finland between December 2008 and February 2010, and the ion-induced nucleation fraction was estimated to be around 1.3 % ± 0.4 % at 2 nm and 1.5 % at 1.4 nm, on average.

TL;DR: In this paper, the authors investigated the dependence of the aerosol number size distribution, mass concentration and chemical composition on the daytime mixing layer height (MLH) in urban Beijing and explored the size distribution and chemical compositions-resolved dry aerosol light extinction.
