Effects of marine fuel sulfur restrictions on particle number concentrations and size distributions in ship plumes in the Baltic Sea [PDF]

Atmospheric Chemistry and Physics, 2021
Exhaust emissions from shipping are a major contributor to particle concentrations in coastal and marine areas. Previously, the marine fuel sulfur content (FSC) was restricted globally to 4.5 m/m%, but the limit was changed to 3.5 m/m% at the beginning ...

In-depth characterization of submicron particulate matter inter-annual variations at a street canyon site in northern Europe [PDF]

Atmospheric Chemistry and Physics, 2021
Atmospheric aerosols play an important role in air pollution. Aerosol particle chemical composition is highly variable depending on the season, hour of the day, day of the week, meteorology, and location of the measurement site.

Applications and limitations of constrained high-resolution peak fitting on low resolving power mass spectra from the ToF-ACSM [PDF]

Atmospheric Measurement Techniques, 2016
The applicability, methods and limitations of constrained peak fitting on mass spectra of low mass resolving power (m∕Δm50 ∼ 500) recorded with a time-of-flight aerosol chemical speciation monitor (ToF-ACSM) are explored. Calibration measurements as well
