Nighttime removal of NOx in the summer marine boundary layer [PDF]

, 2004
The nitrate radical, NO3, and dinitrogen pentoxide, N2O5, are two important components of nitrogen oxides that occur predominantly at night in the lower troposphere. Because a large fraction of NO2 reacts to form NO3 and N2O5 during the course of a night,

Cleaner fuels for ships provide public health benefits with climate tradeoffs

Nature Communications, 2018
Aerosol pollution from shipping contributes to cooling but also leads to premature mortality and morbidity. Here the authors combine emission inventories, atmospheric models and health risk functions to show how cleaner marine fuels will reduce premature

Effects of temperature and salinity on bubble-bursting aerosol formation simulated with a bubble-generating chamber [PDF]

Atmospheric Measurement Techniques, 2022
A new bubble-generating glass chamber with an extensive set of aerosol production experiments is presented. Compared to the experiments described in the literature since the ground-setting works of Edward C.​​​​​​​ Monahan et al.

The Association between Vessel Departures and Air Pollution in Helsinki Port Area 2016–2021

Atmosphere, 2023
European ports are struggling to install enough shore power connections to follow the European Commission initiative, which insists ships that lie alongside to be plugged in and have their auxiliary engines off in EU ports by 2030.

Prediction of size-resolved number concentration of cloud condensation nuclei and long-term measurements of their activation characteristics

Scientific Reports, 2017
Atmospheric aerosol particles acting as cloud condensation nuclei (CCN) are key elements in the hydrological cycle and climate. To improve our understanding of the activation characteristics of CCN and to obtain accurate predictions of their ...

The local ship speed reduction effect on black carbon emissions measured at a remote marine station [PDF]

Atmospheric Chemistry and Physics
Speed restrictions for ships have been introduced locally to reduce the waves and turbulence causing erosion, and safety hazards, and to mitigate the air and underwater noise emissions. Ship speed restrictions could be used to minimize the climate impact

Inverse modeling of black carbon emissions over China using ensemble data assimilation [PDF]

Atmospheric Chemistry and Physics, 2016
Emissions inventories of black carbon (BC), which are traditionally constructed using a bottom-up approach based on activity data and emissions factors, are considered to contain a large level of uncertainty.

PLAM – a meteorological pollution index for air quality and its applications in fog-haze forecasts in North China [PDF]

Atmospheric Chemistry and Physics, 2016
Using surface meteorological observation and high-resolution emission data, this paper discusses the application of the PLAM/h index (Parameter Linking Air-quality to Meteorological conditions/haze) in the prediction of large-scale low visibility and ...
