Cirrus are high altitude clouds composed of ice crystals. They are the first tropospheric
clouds that can scatter incoming solar radiation and the last which can trap outgoing …

Two airborne field campaigns focusing on observations of Arctic mixed-phase clouds and
boundary layer processes and their role with respect to Arctic amplification have been …

Understanding the formation and evolution of ice in clouds requires detailed information on
the size, shape, mass, and optical properties of individual cloud hydrometeors and their bulk …

Ice fog is a natural, outdoor cloud laboratory that provides an excellent opportunity to study
ice microphysical processes. Ice crystals in fog are formed through similar pathways as …

Airborne in-situ cloud measurements were carried out over the northern Fram Strait between
Greenland and Svalbard in spring 2019 and summer 2020. In total, 815 minutes of low-level …

Abstract The Arctic CLoud Observations Using airborne measurements during polar Day
(ACLOUD) campaign was carried out north-west of Svalbard (Norway) between 23 May and …

Marine cold-air outbreaks (MCAOs) strongly affect the Arctic water cycle and, thus, climate
through large-scale air mass transformations. The description of air mass transformations is …

The lack of quantitative characterization of aerosol particles and their loading in the
atmosphere is one of the greatest uncertainties in climate-change science. Improved …

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 …

Mean properties of individual contrails are characterized for a wide range of jet aircraft as a
function of age during their life cycle from seconds to 11.5 h (7.4–18.7 km altitude,− 88 to …
