Sex-specific patterns of symptom burden, psychological distress, and work productivity impairment in post-acute sequelae of COVID-19: a 10-month dynamic cohort study

Abstract Background A considerable proportion of patients experience post-acute sequelae of COVID-19 (PASC). Increasing evidence suggests sex-related differences, yet systematic longitudinal analyses remain limited. This study aimed to examine sex-specific differences in symptoms...

Detectability of solid particle injections into the stratosphere with satellite solar occultation instruments

Stratospheric aerosol injections (SAI) have been proposed as a potential climate intervention to mitigate some effects of global warming. This method involves the idea of injecting sulphur dioxide into the stratosphere. Other ideas include the injection of solid particles, like a...

Dust radiative effects and impact on energy production over the Mediterranean Basin

Abstract. Atmospheric aerosols are among the key factors affecting the Earth’s radiation budget, playing a fundamental role in understanding climate forcing, feedback mechanisms, and their impact on future climate projections and on solar energy systems. More specifically, dust a...

Widespread thermophilization but weak link to climate warming in Europe’s summit plant communities

Abstract Recent changes in alpine vegetation are often attributed to climate warming, particularly community composition shifts towards more warmth-associated species, or thermophilization. Here we assess the link between thermophilization and warming across 53 European mountain...

Middle atmosphere chemical and dynamical effects in the CCMI-2022 stratospheric aerosol injection scenario

Abstract. Stratospheric aerosol injection (SAI) could slow surface warming, however, potential side effects include changes in stratospheric ozone and changes in regional surface temperatures and precipitation resulting from tropical lower stratospheric warming. Previous multi-mo...

How ice apron loss and permafrost degradation promoted the Platteikogel rock slope failure: a thermo-mechanical reconstruction

Abstract. The Alpine cryosphere changes at unprecedented speed, affecting the thermal, hydrological, and mechanical state and behaviour of rock slopes. While numerous studies investigated singular drivers for progressive rock slope failures, the knowledge of hydro-thermo-mechanic...

Long range transport of Canadian wildfire smoke to Europe in 2023: aerosol properties and spectral features of smoke particles

Abstract. The Canadian wildfires of 2023 had an unprecedented biomass burning season spanning from mid-April to late October. Towards the end of this long biomass burning season, there was a rare observation of smoke properties that occurred in about a week interval, that were di...
