This Review aims to summarize the current understanding of bulk tropospheric aqueous-
phase chemistry. Because a complete review of all developments in this area would be …

In the past 40 years, atmospheric chemists have come to realize that halogens exert a
powerful influence on the chemical composition of the troposphere and through that …

Massive Australian wildfires lofted smoke directly into the stratosphere in the austral summer
of 2019/20. The smoke led to increases in optical extinction throughout the midlatitudes of …

The nitrate radical, NO3, is photochemically unstable but is one of the most chemically
important species in the nocturnal atmosphere. It is accompanied by the presence of …

Sea spray aerosol (SSA) is the largest natural source of aerosols in the troposphere, and
has profound potential significance for climate change, visibility, and human health. It has …

Halogen chemistry is well known for ozone destruction in the stratosphere, however reactive
halogens also play an important role in the chemistry of the troposphere. In the last two …

Sea spray aerosol particles (SSA), formed through wave breaking at the ocean surface,
contribute to natural aerosol particle concentrations in remote regions of Earth's atmosphere …

Our understanding of the processes that control the burden and budget of tropospheric
ozone has changed dramatically over the last 60 years. Models are the key tools used to …

Reactive uptake of dinitrogen pentaoxide (N2O5) into aqueous aerosols is a major loss
channel for NOx in the troposphere; however, a quantitative understanding of the uptake …

A workshop was held in the framework of the ACCENT (Atmospheric Composition Change–
a European Network) Joint Research Programme on" Aerosols" and the Programme on" …
