Temperature, humidity, and ionisation effect of iodine oxoacid nucleation

Andrea Baccarini, Imad El Haddad, Lubna Dada, Houssni Lamkaddam

Iodine oxoacids are recognised for their significant contribution to the formation of new particles in marine and polar atmospheres. Nevertheless, to incorporate the iodine oxoacid nucleation mechanism into global simulations, it is essential to comprehend ...

Development of C-C and C-O bond cleavage catalysts for the depolymerization of plastics

Wei-Tse Lee

Chemical recycling of plastics provides more flexibility for materials circulation than landfill disposal or incineration. Intensive research efforts have been devoted to maximizing the efficiency of chemical recycling through catalyst development. The fro ...

MoMuCAMS – A newly developed Helikite-based modular platform for aerosol and trace gas vertical measurements

Julia Schmale, Andrea Baccarini, Roman Pohorsky

MoMuCAMS (Modular, Multiplatform-Compatible Air Measurement System) is a newly developed system for aerosol and trace gas measurements in the lower atmosphere, which offers possibilities for detailed analysis at the interface of the boundary layer and free ...

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, ...

Evolution of microstructural changes in cement paste during environmental drying

Karen Scrivener, Fabien Jacques Michel Georget, Hamed Maraghechi, Wioletta Soja

Exposure of concrete to the atmosphere changes the microstructure of the cement paste. However, knowledge about the alteration of the porosity due to drying is typically not considered in deterioration processes of the hardened cement paste. The purpose of ...

Three-dimensional radiative transfer effects on airborne and ground-based trace gas remote sensing

Alexis Berne, Dominik Brunner, Thomas Wagner

Air mass factors (AMFs) are used in passive trace gas remote sensing for converting slant column densities (SCDs) to vertical column densities (VCDs). AMFs are traditionally computed with 1D radiative transfer models assuming horizontally homogeneous condi ...

Space debris that re-enter the Earth's atmosphere can be partially or fully ablated along the trajectory path after hitting the atmosphere layers, once these become denser (approximately below 82 km). This paper combines re-entry survival analysis to by-pr ...
