Determining stages of cirrus evolution: a cloud classification scheme [PDF]

Atmospheric Measurement Techniques, 2017
Cirrus clouds impose high uncertainties on climate prediction, as knowledge on important processes is still incomplete. For instance it remains unclear how cloud microphysical and radiative properties change as the cirrus evolves. Recent studies classify

Factors controlling contrail cirrus optical depth

, 2009
Aircraft contrails develop into contrail cirrus by depositional growth and sedimentation of ice particles and horizontal spreading due to wind shear.

PROPERTIES OF GALACTIC CIRRUS CLOUDS OBSERVED BY BOOMERANG [PDF]

The Astrophysical Journal, 2010
The physical properties of galactic cirrus emission are not well characterized. BOOMERanG is a balloon-borne experiment designed to study the cosmic microwave background at high angular resolution in the millimeter range. The BOOMERanG 245 and 345GHz channels are sensitive to interstellar signals, in a spectral range intermediate between FIR and ...

An overview of the microphysical structure of cirrus clouds observed during EMERALD-1

, 2004
High-resolution ice microphysical, turbulence, heat and water vapour flux data in cirrus clouds were collected by the Airborne Research Australia’s (ARA) Egret Grob 520T research aircraft during the first EgretMicrophysics with Extended Radiation and ...

Chemical composition of ambient aerosol, ice residues and cloud droplet residues in mixed-phase clouds: single particle analysis during the Cloud and Aerosol Characterization Experiment (CLACE 6) [PDF]

, 2009
Two different single particle mass spectrometers were operated in parallel at the Swiss High Alpine Research Station Jungfraujoch (JFJ, 3580 m a.s.l.) during the Cloud and Aerosol Characterization Experiment (CLACE 6) in February and March 2007.

Wildebeest movement responses to electric conservation fencing in the African Savannah ecosystem

Conservation Science and Practice, EarlyView.
These findings provide GPS‐based empirical evidence of how a newly constructed electric conservation fence alters migratory wildebeests, and show that effects are context‐dependent across habitat type, time of day, and distance to the boundary. While such fences can reduce human–wildlife conflict and support conservation goals, they must be carefully ...

Ice nucleation under cirrus cloud conditions [PDF]

, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

Situated Attention and Strategic Leadership Interfaces: The Role of CEO Humility and Digital Transformation Urgency for Corporate Venture Capital Investments

Journal of Management Studies, EarlyView.
Abstract Integrating the attention‐based view with the strategic leadership interfaces perspective, we propose a theoretical model of situational urgency mechanisms influencing the allocation of CEOs' attention towards responsive actions. Specifically, we theorize upon the role of humility, which leads CEOs towards embracing interfaces and makes them ...
