New particle formation and its effect on cloud condensation nuclei abundance in the summer Arctic: a case study in the Fram Strait and Barents Sea [PDF]

Atmospheric Chemistry and Physics, 2019
In a warming Arctic the increased occurrence of new particle formation (NPF) is believed to originate from the declining ice coverage during summertime.

Bayesian Calibration of a Large‐Eddy Resolving Model Towards Campaign Measurements With an Ensemble Kalman Smoother

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Large‐eddy simulations (LES) are commonly employed to study small‐scale weather phenomena and to validate coarser models. Like larger‐scale weather and climate models, they contain weakly constrained parameters and use physical inputs with associated uncertainties, such as initial conditions or forcing. This study assesses the viability of the

‘EINEN FILM DREHEN’: TECHNOPOLITICAL TURNS AND THE RENDERING OPERATIONAL OF SUBJECTIVITY IN FAROCKI'S LEBEN–BRD (1990) AND PETZOLD'S BARBARA (2012)

German Life and Letters, Volume 79, Issue 3, Page 396-418, July 2026.
ABSTRACT This article analyses the ‘Gestus’ of turning in films by Harun Farocki and Christian Petzold, in light of a central claim of Andrew Webber's esteemed theoretical work on film: that film has the power to uncover unconscious processes through which subjects come into being and are made operational for political regimes.

Response of mixed-phase cloud microphysics to aerosol perturbations at the contrasting sites of Limassol, Cyprus, and Punta Arenas, Chile [PDF]

EPJ Web of Conferences
Based on combined lidar-radar observations, two mixed-phase cloud cases from Limassol and Punta Arenas are studied. While the mixed-phase cloud observed over Limassol was embedded in a dust plume, the case over Punta Arenas was associated with ...

The sensitivity of the colour of dust in MSG-SEVIRI Desert Dust infrared composite imagery to surface and atmospheric conditions [PDF]

Atmospheric Chemistry and Physics, 2019
Infrared “Desert Dust” composite imagery taken by the Spinning Enhanced Visible and InfraRed Imager (SEVIRI), onboard the Meteosat Second Generation (MSG) series of satellites above the equatorial East Atlantic, has been widely used for more than a ...

Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

What Is Triggering Ice in Mixed‐Phase Clouds: A Process Analysis With ECHAM6.1‐HAM2.3 Using the Factorial Method

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Mixed‐phase clouds can be found at temperatures between 0 and −38° ${}^{\circ}$C and consist of supercooled cloud droplets and ice crystals. The phase of mixed‐phase clouds is crucial for the radiation budget, which determines the atmosphere's energy balance.
