• Modeling atmospheric aging of small-scale wood combustion emissions : distinguishing causal effects from non-causal associations 

  Leinonen, Ville; Tiitta, Petri; Sippula, Olli; Czech, Hendryk; Leskinen, Ari; Isokääntä, Sini; Karvanen, Juha; Mikkonen, Santtu (Royal Society of Chemistry (RSC), 2022)

  Small-scale wood combustion is a significant source of particulate emissions. Atmospheric transformation of wood combustion emissions is a complex process involving multiple compounds interacting simultaneously. Thus, an ...

• Effect of fuel composition on the conversion of fuel-N to nitrogen oxides in the combustion of small single particles 

  Hämäläinen, Jouni (1995)

  Older fuels produce more N₂O in fluidized bed combustion than younger fuels. In this study the effect of fuel composition on the formation of nitrogen oxides was examined with solid fuels and model compounds at 1073 K, the ...

• Effect of stratospheric aerosol injection strategy on radiative forcing and precipitation 

  Miettinen, Liisa (2023)

  Tutkielmassa tarkastellaan yläilmakehän rikki-injektioihin perustuvaa vakio- ja vuodenajan mukaan vaihtelevaa ilmastonmuokkausstrategiaa. Vakiostrategiassa rikkiä lähetetään jatkuvasti päiväntasaajalle, ja vaihtelevassa ...

• Natural Marine Precursors Boost Continental New Particle Formation and Production of Cloud Condensation Nuclei 

  de Jonge, Robin Wollesen; Xavier, Carlton; Olenius, Tinja; Elm, Jonas; Svenhag, Carl; Hyttinen, Noora; Nieradzik, Lars; Sarnela, Nina; Kristensson, Adam; Petäjä, Tuukka; Ehn, Mikael; Roldin, Pontus (American Chemical Society, 2024)

  Marine dimethyl sulfide (DMS) emissions are the dominant source of natural sulfur in the atmosphere. DMS oxidizes to produce low-volatility acids that potentially nucleate to form particles that may grow into climatically ...

• Predicting hygroscopic growth of organosulfur aerosol particles using COSMOtherm 

  Li, Zijun; Buchholz, Angela; Hyttinen, Noora (Copernicus, 2024)

  Organosulfur (OS) compounds are important sulfur species in atmospheric aerosol particles, due to the reduction of global inorganic sulfur emissions. Understanding the physicochemical properties, such as hygroscopicity, ...
