Particle flux–gradient relationships in the high Arctic: emission and deposition patterns across three surface types Open
The Arctic is experiencing a warming much faster than the global average and aerosol–cloud–sea–ice interactions are considered to be one of the key features of the Arctic climate system. It is therefore crucial to identify particle sources…

Evolution of the size and composition of ice nucleating particles within the synoptic context of the Arctic melt onset Open
The Arctic region is undergoing rapid changes caused by a warming climate and positive radiative feedback loops associated with rapidly-declining sea ice. Clouds play a key role in melt onset timing and annual extent of sea ice loss by mod…

Influence of free tropospheric aerosols on the microphysical properties of a coupled low-level cloud in the central Arctic: a case study from the ARTofMELT expedition.  Open
Low-level mixed-phase clouds (LLMPCs) containing both ice and supercooled liquid water are ubiquitous in the Arctic and play a crucial role for radiative fluxes. Mixed-phase clouds are inherently instable due to the competition over water …

Identification Of A Regionally Coherent Subseasonal Signal Of Stable Isotopes In Tropical Andean Precipitation Open
Limited observations and the lack of comprehensive understanding of the controls on the isotopic content of precipitation severely limit paleoclimate reconstructions in the outer tropical Andes. This study examines four years of daily obse…

Modelling the impact of atmospheric heat accumulation on glacier mass balance Open
Air temperature (Ta) is ubiquitous in empirical modelling of future glacier extent. However, we argue that this long-held convention should be overturned in favour of the equivalent temperature Te, because the latter is proportional to the…
