Elucidating the mechanisms of atmospheric new particle formation in the highly polluted Po Valley, Italy

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 2423-2441 (2024)

New particle formation (NPF) is a major source of aerosol particles and cloud condensation nuclei in the troposphere, playing an important role in both air quality and climate. Frequent NPF events have been observed in heavily polluted urban environm

Analysis of atmospheric particle growth based on vapor concentrations measured at the high-altitude GAW station Chacaltaya in the Bolivian Andes

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 1315-1328 (2024)

Early growth of atmospheric particles is essential for their survival and ability to participate in cloud formation. Many different atmospheric vapors contribute to the growth, but even the main contributors still remain poorly identified in many env

Arctic observations of hydroperoxymethyl thioformate (HPMTF) – seasonal behavior and relationship to other oxidation products of dimethyl sulfide at the Zeppelin Observatory, Svalbard

Autor: K. Siegel, Y. Gramlich, S. L. Haslett, G. Freitas, R. Krejci, P. Zieger, C. Mohr

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 7569-7587 (2023)

Dimethyl sulfide (DMS), a gas produced by phytoplankton, is the largest source of atmospheric sulfur over marine areas. DMS undergoes oxidation in the atmosphere to form a range of oxidation products, out of which sulfuric acid (SA) is well known for

Effect of Long‐Range Transported Fire Aerosols on Cloud Condensation Nuclei Concentrations and Cloud Properties at High Latitudes

Publikováno v: Geophysical Research Letters, Vol 51, Iss 6, Pp n/a-n/a (2024)

Abstract Active vegetation fires in south‐eastern (SE) Europe resulted in a notable increase in the number concentration of aerosols and cloud condensation nuclei (CCN) particles at two high latitude locations—the SMEAR IV station in Kuopio, Finl

Revealing the chemical characteristics of Arctic low-level cloud residuals – in situ observations from a mountain site

Autor: Y. Gramlich, K. Siegel, S. L. Haslett, G. Freitas, R. Krejci, P. Zieger, C. Mohr

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 6813-6834 (2023)

The role aerosol chemical composition plays in Arctic low-level cloud formation is still poorly understood. In this study we address this issue by combining in situ observations of the chemical characteristics of cloud residuals (dried liquid cloud d

Measurement report: Molecular-level investigation of atmospheric cluster ions at the tropical high-altitude research station Chacaltaya (5240 m a.s.l.) in the Bolivian Andes

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 4559-4576 (2023)

Air ions are the key components for a series of atmospheric physicochemical interactions, such as ion-catalyzed reactions, ion-molecule reactions, and ion-induced new particle formation (NPF). They also control atmospheric electrical properties with
