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 …

Low-level (cloud tops below 2 km) mixed-phase clouds are important in amplifying warming
in the Arctic region through positive feedback in cloud fraction, water content and phase. In …

Northern lakes are considered a major source of atmospheric methane (CH4), a potent
GHG,. However, large uncertainties in their emissions (7–26 Tg CH4 yr–1; ref.) arise from …

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 …

Clouds are assumed to play an important role in the Arctic amplification process. This
motivated a detailed investigation of cloud processes, including radiative and turbulent …

The main in situ database for numerical weather prediction currently relies on radiosonde
and airliner observations, with large systematic data gaps: horizontally in certain countries …

Direct measurements of NO x, CO and aromatic volatile organic compound (VOC)(benzene,
toluene, C 2-benzenes and C 3-benzenes) flux were made for a central area of Beijing using …

The Earth's surface is heterogeneous at multiple scales owing to spatial variability in various
properties. The atmospheric responses to these heterogeneities through fluxes of energy …

For research in the atmospheric boundary layer and in the vicinity of wind turbines, the
turbulent 3D wind vector can be measured from fixed-wing unmanned aerial systems (UAS) …

The Arctic marine climate system is changing rapidly, which is seen in the warming of the
ocean and atmosphere, decline of sea ice cover, increase in river discharge, acidification of …
