This paper deals with the composition and chemical processes occurring in the neutral
atmosphere of Venus. Since the last synthesis, observers as well as modellers have …

The HITRAN database is a compilation of molecular spectroscopic parameters. It was
established in the early 1970s and is used by various computer codes to predict and …

This paper describes the status of the 2008 edition of the HITRAN molecular spectroscopic
database. The new edition is the first official public release since the 2004 edition, although …

The updated 2009 edition of the spectroscopic database GEISA (Gestion et Etude des
Informations Spectroscopiques Atmosphériques; Management and Study of Atmospheric …

The multiphase oxidation of SO2 to sulfate in aerosol particles is a key process in
atmospheric chemistry. However, there is a large gap between the observed and simulated …

The TROPOspheric Monitoring Instrument (TROPOMI) onboard the Copernicus Sentinel-5
Precursor (S-5P) platform will measure ultraviolet earthshine radiances at high spectral and …

Venus Express measurements of the vertical profiles of SO and SO2 in the middle
atmosphere of Venus provide an opportunity to revisit the sulfur chemistry above the middle …

We present here three-dimensional simulations of the Venus photochemistry and clouds
from the ground to the bottom of the thermosphere. For that purpose, we have implemented …

Starting on 3 May 2018, a series of eruptive fissures opened in Kīlauea Volcano's lower East
Rift Zone (LERZ). Over the course of the next 3 months, intense degassing accompanied …

Identification of unambiguous signals of volcanic unrest is crucial in hazard assessment.
Processes leading to phreatic and phreatomagmatic eruptions remain poorly understood …
