This review focuses on the observed characteristics of atmospheric new particle formation
(NPF) in different environments of the global troposphere. After a short introduction, we will …

New particle formation (NPF) represents the first step in the complex processes leading to
formation of cloud condensation nuclei. Newly formed nanoparticles affect human health, air …

Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere,
central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as …

Homogeneous nucleation and subsequent cluster growth leads to the formation of new
aerosol particles in the atmosphere. The nucleation of sulfuric acid and organic vapours is …

Iodine is an essential element in the human diet and a deficiency can lead to a number of
health outcomes collectively termed iodine deficiency disorders (IDD). The geochemistry of …

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 …

The atmospheric chemistry of iodine is important in diverse ways. First, it provides the route
for iodine, which is an essential dietary element for mammals, to be transported from its …

Vanadium is special in at least two respects: on the one hand, the tetrahedral anion
vanadate (v) is similar to the phosphate anion; vanadate can thus interact with various …

Iodine was discovered as a novel element in 1811 during the Napoleonic Wars. To
celebrate the bicentennial anniversary of this event we reflect on the history and highlight …

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 …
