High altitude mountaintop observatories provide the opportunity to study aerosol properties
in the free troposphere without the added expense and difficulty of making airborne …

Among the worldwide existing long-term aerosol monitoring sites, the Jungfraujoch (JFJ)
belongs to the category where both free tropospheric (FT) conditions and influence from …

A hygroscopicity tandem differential mobility analyzer (HTDMA) was used to measure the
water uptake (hygroscopicity) of secondary organic aerosol (SOA) formed during the …

Improving our understanding of the spatial pattern of the urban heat island (UHI) effect is an
important aspect of current studies on the urban thermal environment. In this study, we …

Current research on the surface urban heat island (SUHI) effect rarely address the
discussion of what exactly is the 'island'of urban surface thermal environment. Given this …

Given the sensitivity of the Arctic climate to short-lived climate forcers, long-term in situ
surface measurements of aerosol parameters are useful in gaining insight into the …

In order to assess the evolution of aerosol parameters affecting climate change, a long-term
trend analysis of aerosol optical properties was performed on time series from 52 stations …

This paper presents the light-scattering properties of atmospheric aerosol particles
measured over the past decade at 28 ACTRIS observatories, which are located mainly in …

In this study, we present results from 12 years of black carbon (BC) measurements at 14
sites around the Helsinki metropolitan area (HMA) and at one background site outside the …

Currently many ground-based atmospheric stations include in-situ measurements of aerosol
physical and optical properties, resulting in more than 20 long-term (> 10 yr) aerosol …
