Coupling an aerosol box model with one-dimensional flow: a tool for understanding observations of new particle formation events

Autor: Niku Kivekäs, Jimmie Carpman, Pontus Roldin, Johannes Leppä, Ewan O’Connor, Adam Kristensson, Eija Asmi

Publikováno v: Tellus: Series B, Chemical and Physical Meteorology, Vol 68, Iss 0, Pp 1-14 (2016)

Field observations of new particle formation and the subsequent particle growth are typically only possible at a fixed measurement location, and hence do not follow the temporal evolution of an air parcel in a Lagrangian sense. Standard analysis for

Publikováno v: Oceanologia, Vol 58, Iss 1, Pp 1-12 (2016)

In this study, we evaluated 10 months data (September 2009 to June 2010) of atmospheric aerosol particle number size distribution at three atmospheric observation stations along the Baltic Sea coast: Vavihill (upwind, Sweden), Utö (upwind, Finland),

Source Contributions to Rural Carbonaceous Winter Aerosol in North-Eastern Poland

Autor: Adam Kristensson, Stina Ausmeel, Julija Pauraite, Axel Eriksson, Erik Ahlberg, Steigvilė Byčenkienė, Anna Degórska

Publikováno v: Atmosphere, Vol 11, Iss 3, p 263 (2020)

Concentrations of aerosol particles in Poland and their sources are rarely discussed in peer-reviewed journal articles despite serious air quality issues. A source apportionment of carbonaceous aerosol particles was performed during winter at a rural

No Particle Mass Enhancement from Induced Atmospheric Ageing at a Rural Site in Northern Europe

Autor: Erik Ahlberg, Stina Ausmeel, Axel Eriksson, Thomas Holst, Tomas Karlsson, William H. Brune, Göran Frank, Pontus Roldin, Adam Kristensson, Birgitta Svenningsson

Publikováno v: Atmosphere, Vol 10, Iss 7, p 408 (2019)

A large portion of atmospheric aerosol particles consists of secondary material produced by oxidation reactions. The relative importance of secondary organic aerosol (SOA) can increase with improved emission regulations. A relatively simple way to st

Usage of long-term forest research networks to advance understanding of ecosystem services – CLIMB-FOREST

Autor: Holger Lange, Jaana Bäck, Georg Jocher, Natascha Kljun, Anne Klosterhalfen, Alexander Knohl, Natalia Kowalska, Adam Kristensson, Corinna Rebmann, Teresa Saura-Yera, Alberto Vilagrosa

Utilizing forest ecosystems to mitigate climate change effects and to preserve biodiversity requires detailed insights into the feedbacks between forest type, climatic and soil conditions, and in particular forest management history and practice. Ana

Soot, or black carbon (BC), aerosol is a major climate forcer with severe health effects. The impacts depend strongly on particle number concentration, size and mixing state. This work reports on two field campaigns at nearby urban and rural sites, 6
