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 …

Civil aviation is fast-growing (about+ 5% every year), mainly driven by the developing
economies and globalisation. Its impact on the environment is heavily debated, particularly …

Interest in green chemistry and clean processes has grown so much in recent years that
topics such as fluorous biphasic catalysis, metal organic frameworks, and process …

In situ measurements of the chemical composition of individual aerosol particles at altitudes
between 5 and 19 kilometers reveal that upper tropospheric aerosols often contained more …

We provide an overview of geoengineering by stratospheric sulphate aerosols. The state of
understanding about this topic as of early 2008 is reviewed, summarizing the past 30 years …

To better represent the indirect effect of aerosols on climate, a size‐resolved simulation of
aerosol microphysics, size distributions, number and mass concentrations has been …

Aerosol surface area distributions inferred from satelliteborne 1‐μm extinction
measurements are used as input to a two‐dimensional model to study the effects of …

During the 20th century, the world's transportation system has changed dramatically with the
gradual emergence of a large fleet of commercial aircraft. Today, thousands of aircraft carry …

Stratospheric aerosol, noted after large volcanic eruptions since at least the late 1800s, were
first measured in the late 1950s, with the modern continuous record beginning in the 1970s …

Cirrus cloud formation is believed to be dominated by homogeneous freezing of
supercooled liquid aerosols in many instances. Heterogeneous ice nuclei such as mineral …
