Effect of ambient atmosphere on the formation and evolution of conjugated structure of pre-oxidized polyacrylonitrile

open access: yesMaterials Research Express, 2022
The ambient atmosphere has the remarkable effect on the chemical reaction mechanism and the formation of characteristic chemical structures and conjugated structures for pre-oxidized polyacrylonitrile (PAN).

Boundary layer new particle formation over East Antarctic sea ice – possible Hg-driven nucleation? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Aerosol observations above the Southern Ocean and Antarctic sea ice are scarce. Measurements of aerosols and atmospheric composition were made in East Antarctic pack ice on board the Australian icebreaker Aurora Australis during the spring of 2012.

Added Value of Atmosphere-Ocean Coupling in a Century-Long Regional Climate Simulation

open access: yesAtmosphere, 2019
A twentieth century-long coupled atmosphere-ocean regional climate simulation with COSMO-CLM (Consortium for Small-Scale Modeling, Climate Limited-area Model) and NEMO (Nucleus for European Modelling of the Ocean) is studied here to evaluate the added ...

Soaring energetics and glide performance in a moving atmosphere

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2016
Here, we analyse the energetics, performance and optimization of flight in a moving atmosphere. We begin by deriving a succinct expression describing all of the mechanical energy flows associated with gliding, dynamic soaring and thermal soaring, which ...

Transformer-based Atmospheric Density Forecasting [PDF]

open access: yesarXiv, 2023
As the peak of the solar cycle approaches in 2025 and the ability of a single geomagnetic storm to significantly alter the orbit of Resident Space Objects (RSOs), techniques for atmospheric density forecasting are vital for space situational awareness.
