The eruption of the Hunga Tonga–Hunga Ha'apai volcano on 15 January 2022 offered a
good opportunity to explore the early impacts of tropical volcanic eruptions on stratospheric …

Chemical processes involving chlorine nitrate (ClONO2) at the surface of stratospheric
aerosols are crucial to ozone depletion. Herein, we show a reaction route for the formation of …

The adsorption of atmospheric gas molecules and the low-dimensional TiO 2 species are
relevant for the atmospheric photochemistry and energy-related photoelectrochemistry. In …

It is well-known that the aqueous-phase processing of chlorine nitrate (ClONO2) plays a
crucial role in ozone depletion. However, many of the physical and chemical properties of …

We retrieved lower stratospheric vertical profiles of O 3, HNO 3, and HCl from solar spectra
taken with a ground-based Fourier transform infrared spectrometer (FTIR) installed at Syowa …

Abstract The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) was a
limb-viewing infrared Fourier transform spectrometer that operated from 2002 to 2012 …

Abstract The Montreal Protocol has banned the production of long-lived halogen-containing
molecules such as chlorofluorocarbons (CFCs) that are responsible for the widespread …

The direct radiative forcing (RF) from halocarbons is reasonably well characterized.
However, the forcing due to polyatomic halogen reservoir and halocarbon breakdown …

We use ground-based spectroscopic remote sensing measurements of the stratospheric
trace gases O3, HCl, ClO, BrO, HNO3, NO2, OClO, ClONO2, N2O and HF, along with …

Computational models of atmospheric composition are not always physically consistent. For
example, not all models respect fundamental conservation laws such as conservation of …
