Airborne mineral dust particles can act as natural seeds for cirrus clouds in the upper
troposphere. However, the atmospheric abundance of dust is unconstrained in cirrus …

Cirrus clouds are ubiquitous, long-lived, high-level ice clouds that exert a considerable
global radiative effect on the climate system. This review assesses recent observational and …

The microphysical and radiative properties of cirrus clouds continue to be beyond
understanding and thus still represent one of the largest uncertainties in the prediction of the …

This study presents airborne in situ and satellite remote sensing climatologies of cirrus
clouds and humidity. The climatologies serve as a guide to the properties of cirrus clouds …

Cirrus ice crystals are produced heterogeneously on ice‐nucleating particles (INPs) and
homogeneously in supercooled liquid solution droplets. They grow by uptake of water …

The number concentration of cloud particles is a key quantity for understanding aerosol–
cloud interactions and describing clouds in climate and numerical weather prediction …

The radiative role of ice clouds in the atmosphere is known to be important, but uncertainties
remain concerning the magnitude and net effects. However, through measurements of the …

Despite their proven importance for the atmospheric radiative energy budget, the effect of
cirrus on climate and the magnitude of their modification by human activity is not well …

Atmospheric ice formation in cirrus clouds is often initiated by aerosol particles that act as ice-
nucleating particles. The aerosol–cloud interactions of soot and associated feedbacks …

Ice crystal submicron structures have a large impact on the optical properties of cirrus clouds
and consequently on their radiative effect. Although there is growing evidence that …
