Emergence of representative signals for sudden stratospheric warmings beyond current predictable lead times

Major sudden stratospheric warmings (SSWs) are extreme wintertime circulation events of the Arctic stratosphere that are accompanied by a breakdown of the polar vortex and are considered an important source of predictability of tropospheric weather on subs ...

Impact of warm air mass intrusions on atmospheric chemistry and microphysics: Observations during MOSAiC

Julia Schmale, Ivo Fabio Beck, Lubna Dada

Arctic winter is dominated by anthropogenic haze, while pollution transport from mid-latitudes decreases in summertime. As a result, aerosol concentrations reach a maximum in winter and drop to minimum in summer. What happens during the season transition, ...

Regimes of primary production and their drivers in Alpine streams

Tom Ian Battin, Amber Joy Ulseth, Marta Boix Canadell, Mélanie Clémençon

Primary production is a fundamental ecosystem process that influences nutrient and carbon cycling, and trophic structure in streams. The magnitude and timing of gross primary production (GPP) are typically controlled by hydrology, light, nutrient availa ...

Degradation study on molecules released from laser-based jet injector

Christophe Moser, Jan Krizek, Barbora Lavickova

Development of needle-free methods to administer injectable therapeutics has been researched for a few decades. We focused our attention on a laser-based jet injection technique where the liquid-jet actuation mechanism is based on optical cavitation. This ...

Stream temperature and discharge evolution in Switzerland over the last 50 years: annual and seasonal behaviour

Michael Lehning, Wolf Hendrik Huwald, Adrien Michel, Bettina Schaefli, Tristan Jonas Brauchli

Stream temperature and discharge are key hydro- logical variables for ecosystem and water resource management and are particularly sensitive to climate warming. Despite the wealth of meteorological and hydrological data, few studies have quantified observe ...

Daily entropy of dissolved oxygen reveals different energetic regimes and drivers among high‐mountain stream types

Tom Ian Battin, Mélanie Clémençon

High‐resolution time series of dissolved oxygen (DO) have revealed different ecosystem energetics regimes across various stream types. Ecosystem energetic regimes are relevant to better understand the transformation and retention of nutrients and carbon in ...

Biomass burning aerosol as a modulator of the droplet number in the southeast Atlantic region

Athanasios Nenes

The southeastern Atlantic (SEA) and its associated cloud deck, off the west coast of central Africa, is an area where aerosol–cloud interactions can have a strong radiative impact. Seasonally, extensive biomass burning (BB) aerosol plumes from southern Afr ...

Spatiotemporal Drivers of CO2 Dynamics and Evasion Fluxes from Mountain Streams

Asa Lovisa Viktoria Horgby

Inland waters are key components of the global carbon cycle, emitting a substantial amount of carbon dioxide (CO2) to the atmosphere. Climate change and global warming affect mountain catchments significantly, leading to glacier retreat and changing precip ...
